I have no brand biasness and just want to get some honest pro / cons on each product. I just want to make the right choice. I plan on getting an exhaust system, TBE or catback, and an intake if needed (probably not, just a high-flow filter). I recently got the Delta Dash product, and it is ABSOLUTELY AMAZING. I wish the Honda ECU had a similar product. Sheesh!

I know the delta dash will allow you to tune the ecutek once have your ecu reflashed.

I thought both are user tunable, if you so desire (and able to :) )

Not sure how much ECUTEC reflash will cost for the STi.
It is like $6-700 for the WRX.

Plus the UTEC is out and ECUTEC is not so right now UTEC is on top. ;)

Agreed, but ECUTEK is releasing in May. I'm not in too big of a hurry. We can compare the two on normal WRX's if needed to get comparision data.

Some of you have been around long enough to know better.

The tuner is more important than the tool.

My point was since you already have the delta dash you might think about going with the ecutek since I hear the price is going to be 650. Ends up being cheaper for you. should be able to do the same things, some things that utec can't do yet like rev limiter and stuff.

you need to consider the thrid option which has both

cobb access tuner .. reflash technology and full user adjustability

If you add the cost of the ecutek or cobb access port. both are about $650. Then you have to buy the tuner package for both. You already have the delta dash that can be used so it would be cheaper to stick with that. But there are other options like cobb and utec. Just going to cost you more. They all have different features pros and cons

I'm waiting for the AccessPORT to be released. This product seems to be the bang for the buck for my modest needs on the STi with room to expand if needed.

Hydra- don't forget the Hydra.

No idea if it will pan out, but looks really cool with loads of features.

I think the UTEC has too much for me to screw with and I could blow things up.

Whatever I get will get tuned on a dyno by a pro.

UTEC scares me, don't know enough about tuning to start futzing with it

ecutek equals nice, safe plugged in power, good enough for me

The user tune resolutions of the ECUTEK in NO WAY compare to the tunability of the UTEC.

seriously, people need to realize that the tuner capabilities of the DD are no where near that of a UTEC. DD lets you adjusts boost and over all , across the board fuel/timing. also there are two WASTEGATE maps, NOT fuel maps.

However I will agree with turboICE, it's more the tuner than the tuning tool most of the time.

for real. you can do very little "tuning" with a user-tune ECUTek reflash. i have had one of them. It's a joke really the amount of tuning you can do.

Do you mean its less tunable AFTER the tuner has tweaked it on a dyno? Or that the tuner has less tools available for a good tune? Because honestly, after the car is adjusted on a dyno, i'm not going to be playing around with it that much.

Can you also explain the key differences in the ECUTEK having selectable wastegate maps vs the UTEC fuel maps. Thanks

ECUtek is not really "user" tunable in the sense that UTEC is. DeltaDash gives you some basic timing controls, etc. but nothing like DeltaECU.

It's amazing how much stuff you can control with a real ECUtek console... per-cell control in all the maps, total authority over the running state of the motor. It's secksay. :D

sound like you're having fun with your toy:p

No it is just les tunable than a UTEC. If you get ECUTEK and dont want to play with it and trust your tuner, then there's really no point to get DD.

With the UTEC you have X amount of maps. these maps contain boost, fuel and timing maps. with the map switching feature you can change between them on the fly.

With ECUTEK, the tuner can program two wastegate maps. One for "normal" max performance, and one for lower boost, even just wastegate pressure. You must tell you tuner what you want on the second map though.

Here's the catch, in DD you can adjust wastegate duty cycle. so you can dial in more or less boost, but it effect BOTH maps. So if you pull your WDC down to 0% (which will give you WG pressure of about 7-9psi) this will happen in both maps. making you build no boost, no matter what map you are in. Kinda silly i think.

Plan your car. Make your mods. Get a dyno-tuned reflash. Drive your car.

With the ecutek software you to global changes, meaning, if the fuel map is designed to run a fuel curve of say 10.8:1 at 5000 RPM and 11:1 at 7000 RPM, you can only pull direct percentages of fuel across the ENTIRE map.

I.E.

FUEL: -30%
TIMING: +5
BCSDC: +20%

No where did I have the chance of saying "only take out 30% on the top, and only 20% at 5000 RPM).

You have to pray your tuner had a proper curve outright, or your going to have issues quick with broad changes like that.

I can adjust a UTEC every 250 RPM across almost a dozen load columns.

For absolute clarity here, Jorge is talking about the User-Tune functionality via DeltaDash performed on an EcuTek reflashed ECU (just for those who don't know).

You have to pray your tuner had a proper curve outright, or your going to have issues quick with broad changes like that.
What issues? A goofy knock correction table and the car running fine with lower than optimal power?

The 'Open-Loop Fueling' adjustments in User-Tune-enabled EcuTek reflashes are very pointedly for very minor adjustments. Adjustments on the order of 30% are not even possible with a properly configured reflash done by a responsible tuner.

Any solution is capable of making good safe power in the hands of a good tuner. There are about 10 different questions one should be answering before picking one or the other solution.

A: exactly.. and that ultimately translates to drivability issues. Or worse. I've seen situations where the ignition correction grid was setup wrong, and crusing around causes positive ignition correction to be applied in certain places in the map, especially at VE peak, to have user tune screw it up by leaning out causing knock issues... sure, the IC system will eventually re-adjust it's grid value to handle it, but it was AUDIBLE knock while it was happening. That scares me... quite a bit.

B: Agreed on both counts!

sooo true

I really don't know the persistance for poeple to know what the BEST engine management is out there. There is just no REAL and CORRECT answer. The minute you say this is the BETTER products other people are already thinking of the CONS for it. Bottom line is the actual specific purpose of your application, that will drive you specific needs.

For the enthusiast and average spirited-driving Joe the ECUtek re-flash (DeltaECU) (or COBB's AccessECU) wins hans down. Assuming you get a good tune by a professional tuner. Remember DeltaDash is not a tuning software. Luckily they throw in those 2 or 3 items we can play with.

If you are a tweaker and have boat loads of $$$ OR are a rich mom's and papa's little boy and therefore can afford to buy an SR50, then decide si not enough for you so is time to buy a GT35R then discover thre is too much lag so lets now put in a GREEN turbo. Then a product such as UTEC is the correct product for you.

No offense but I really don't like people like the guy that just months ago spend a furtune buying parts for his STi, he even bought a crazzy a$$ expensive MOMO steering wheel with all these electronics gizmos and now he is selling everything. WHAT A WASTE!!! :mad:

I really don't know the persistance for poeple to know what the BEST engine management is out there.
Personally, I just saw it as a new STI owner, who doesn't have a history of knowing the ins and outs of the UTEC's feature list, wanting to know more about the two solutions in comparison so that he can make a judgment for his planned mods.

Not everybody has been reading the technical forums everyday for a few years to know what the UTEC's history or EcuTek's history has been with WRX owners.

*shrug*

Ozy said:I have no brand biasness and just want to get some honest pro / cons on each product. I just want to make the right choice

If I ever get some sort of aftermarket retune, I don't care if its mounted rat brains in a nutrient solution or a custom piece from an formula 1 custom builder.. as long as it gets the job done, gives me what I want and keeps my poor toy from stuffing its pistons..

And.. yes yes yes.. the tuner is more important than the device being tuned. And to the guy who said, dyno tune it and drive it I say (assuming you have a good tuner) dyno tune it and then road tune it and then drive it. Dyno tunes a nice but the road aint a dyno. No one drives a car like it's tuned on the dyno.

Ecutek for the STI will be the right EM for most users. Taking advantage of Subaru’s 4 patients for revolving ignition advance is the advantage over any system that runs constant timing. I have driven many Subarus with Ecutek and I have always been amazed at the smooth OEM performance and drivability. Yes you can have your cake and eat it too.

Subarus make most power with ignition advance over runing alot of boost and lean A/Fs.

IMHO, This is worth waiting for.
Eric

I agree with some of the comments, it is only as good as the tuner. Once you can find a really good tuner, it doesn't matter what software it is, the tuner will make it happen.

I strongly disagree with this statement. The way you make power on ALL turbocharged cars is to cram more air into the cylinders.

Trying to make significant power increase with just ignition timing leads to some pretty nasty peak cylinder pressures and can cause all sorts of problems.

Subaru can keep their patents on the ignition advance. Ever see the power and torque curves on the dyno with the stock ECU? They're all over the place because the stock ECU keeps changing timing and eventually advancing it the the point of detonation and then pulling it back again losing serious power.

With the UTEC in it's current state of tune, I've ecountered no knock on the STi. If you look at the dyno charts for my car, the the UTEC curves are extremely consistent, where as my stock ECU curves were all over (not to mention at least 38 WHP/50ft lbs less).

Stock = poop

A reflash is not "the stock ECU" anymore.

Compare apples to apples.

Utec is the best way to go and those guys are turboxs are very helpful.

Well I guess I have to clear up my statment then. :D

Subarus make the most reliable power runing at max ignition advance before detonation. Runing them leaner just makes them run hotter and and not alow you to run enough igntion advance to make repetable power or IMHO reilable power. Now yes you can cram a larger turbo in and run More Boost and as long as you have enough fuel or octain or both to support the boost you can make alot of power. But Drivablity is affected with lag and Octain when you factor in daily drivable on pump gas.

Why would Subaru go throw the whole trouble of developing revolving ignation advance?

Simple because on the Subaru motor runing high amounts of boost is not possiable with our pump gas octain limits. So instead they try to run Max alowable ignation advance.

For most users again the Ecutek is a great option. Simple because they will not go over the limits of bolt on turbos and mostly run on pump gas unless they drag race. Most track drivers will run a pump gas Map and may and throw in a few gals. of race gas for a extra margin of safty.

The UTEC is very neat but Stock computer with the right tuner behind works very well.

Bottom line if your going to be Modding the crap out of your ride you need a user tunable computer. If your going to throw in a few bolt ons your better of with the stock computer reflashed.

Again IMHO

yeah, yeah, I concurr with above...:rolleyes:

Again I disagree.

I think what you intend to say is that you should stop pushing advance before you get to detonation. This I agree with, but it is far better to drastically increase average cylinder pressure rather then peak cylinder pressures if you are looking for reliability.

Again, I am not suggesting that you should lean out the car to make more power either. If you lean out to the point of detonation your cylinder pressure raises an order of magnitude and all sorts of nasty things happen.

Now let’s deal with the idea of Subaru’s ignition patents. It is clear that Subaru, patents and all, let this car out of the factory in a condition that causes it to detonate. The rise in cylinder pressures from detonation can be catastrophic. If their ignition advance system worked as it should, we all wouldn’t really need any EMS solution beyond a SAFC. If I leave the stock ECU in control of ignition advance, and allow it to decide when to pull back the timing, how long exactly do you expect my motor to last? Ask the guys that have been blowing up on Emanages or Unichips about the knock control system.

When you get to the last degree before detonation, you are really having an impact on your peak cylinder pressure. This last degree may make the “last hp” you can get out of your system, but there is little reason to push the car to this point. I’d go further and say that it is at this last degree where you start getting into the unreliable power zone.

I don’t discount that a re-flash is a good product and I’ve recommended them to our customers who I felt would be better served by them. In the case of the STI, I’d like to know how exactly they are changing the logic of the factory ECU for how it recognizes detonation. We all accept that the factory ECU will run the car into detonation conditions over and over and over. Is the solution with the re-flash to limit the amount of advance that the car can run (which frankly isn’t much different then the UTEC solution) or is it to change the logic for how the factory ECU recognizes and reacts to detonation?

My UTEC limits our STI to the last degree of advance I feel comfortable running. On the dyno I can watch the impact an extra degree or two have on the curve. Before you get to the point of detonation, you end up seeing gains as low as 1-2hp per degree of ignition advance. At this point your only real solution to increasing HP is to add more air to the charge.

What he said...

To quote Clark Turner.... Timing and fuel are not a knob for power. There is one correct fuel curve, and one correct timing curve for a set of aspiration mods.

Just like there is one correct boost curve to maximize and achieve that balance of compressor efficiency and BP/EP ratio.

Each and every tuner has their own style of what they'd like to see while tuning, and what they're willing to sacrifice here and there to achieve >THEIR< ideal setup for a car. But in the end, those of us who've done this enough know that it's all about compromise and blend.

Somewhere in that blend is a swing to either an aggressive blend, or a conservative blend, but a blend nonetheless.

Good stuff too bad its so limited... maybe if they had an online class.

I have ECUTek and it runs like a dream. Of course I only have a vf34 stage4 setup, but for 300 more dollars you can get software for a laptop and you can change whatever you want in your ecu. So that is a total of 950 which is pretty much a Utec. I know, I know what if you don't have a laptop? Well then maybe that isn't the way to go if you like tuning yourself. I personally will never tune my car, but I do have a laptop :) I would say go with whatever you like. If you are not planning on tuning it yourself go with whatever the nearest dyno tuner uses. I would much rather have my ecu pull timing and reduce my power if my engine detonates then just riding through it.

In the grand scheme of daily driving you are not always going to be running in ideal conditions so you need an ecu that can adapt. I am not saying the utec can't, because I really don't know I am just stating that ECUTek can.

Without getting into all the back and forth on the rest (delivered knocking STi's etc) - this is a completely unfair comment/comparison regarding the timing system and very biased and misleading to readers.

By adjusting the MAF signal you are completely misleading the ECU as to the true load the engine is under. To claim a timing system is broken because people have used a tool that causes the ECU to be in completely the wrong load zone in its timing maps is very flawed at best.

The very reason tuning with UTEC's historical piggy back fueling has been so successful with high power applications over other piggyback fuel controllers is because it takes over timing - unadjusted timing maps with the significant MAF adjustment can not be reasonably expected to work properly. The signifcant adjustments you are sending the ECU for instance when you are using larger injectors makes it think its loads are much lower than they really are - you definitely would not want to run the stock timing maps with such misleading MAF readings as would be sent to it otherwise.

When EcuTek is properly tuned with fuel and timing maps based on the modifications to the car and load is properly reported to the timing maps - the timing methodology works extremely well.

True. No question about it. The statement was at best biased. However the car does knock in stock form does it not? Is detonation EVER good?

It should also be noted that the UTEC does not currently piggyback off the stock ECU for fuel control.

In my own experience, if you make advance available to the stock ECU it will make use of it. With this in mind, I’d suggest that most successful ecutek tuners are in fact limiting the advance that the stock ecu CAN run and then providing a high det timing map to operate below that cap. A properly tuned ecutek should not have the authority to advance the car into detonation. To claim that it is better because it can run on the edge of knock and pull itself back in order to get the last reliable HP is ridiculous given that the car detonates in stock form. Detonation (in an EJ motor) is never a good thing.

ECUtek mild tune

250 - 270 whp from 5000 to 6900 peak whp 270

average whp 260

boost @ 265 whp 13.8 psi in 6500 RPM range

A/F 9.8 to 10.2

These engines have the ability to produce power, but you need to make sure that you have the correct components installed. If all your components are matched you can create power very easily, but if your components dont compliment each other then you could very well lose power or not make power efficently.

But back to the point the ECUtek can make efficent power as you can see by the above numbers but the key is

If you want to be your own master tuner then get the UTEC.
If you want an OEM type tune then get the ECUtek,

as someone pointed out both solutions has there pro and cons. You need to identify your need and select accordingly.

That software you are referring to is the DeltaECU produced by ECUTek and is not sold to the public. It is available to professionals only. The Delta Dash is also produced by ECUTek. That piece of software is what is sold to the public. It is a very capable logging tool with the ability to change idle speed and remove up to 5% of advance. That software also has limited capability to change some other parameters of an ECU that has been reflashed by the DeltaECU software. You can learn about both at: www.ecutek.com

Please answer this, I'll be very curious if the answer is yes.

Also the list of "matched" components would be helpful too...

I have been away for a few days and the answer is yes.

It starts with your exhaust components. I was able to go from
170whp to 216 with just bolt on exhaust, no tune piggy back, just the stock ecu, with that I could make a lot of power with very little effort.

This is what I got
HKS headers, turboxs up and down, 5zigen exhaust , greddy fmic, 518g sti injectors. wabro pump. 91 octane
thats all.

Oh and a good tune

WRXzard

I missed the question asking if it was a STi and that answer is no.

2002 EJ20, no head work stock engine just bolt all the bolt on stuff.

WRXzard

Oh and a good tune And a high-reading dyno.

I agree... I'm not calling BS becuse I know all to well what one dyno will show off another, but my biggest concern isn't so much the accuracy of the numbers, so much as the accuracy of your AFR.

That is stupidly rich... For a bunch of reasons, not limited to oil contamination, poor fuel economy, and others.

You talk about efficiency and making reference to subaru's programming philosophy.

This from the same company that decided to program the '04 ECU to sustain stoich while under a WOT transition to reduce emissions... and let's be honest... it's ONLY for emissions. There sure is no performance benefit to it.

They dump fuel like mad and cut the wastegate solenoid signal after 6000 RPM to run you at spring pressure so you don't ever have a chance of blowing the motor up.

I'm willing to understand that the majority of the people here understand that the relationship of HP production and engine life are diametric opposites. It's just a matter of choosing your venom.

Even the best tuned 300WHP car is not going to run 200k miles of abuse. If anything, running it TOO rich will cause it to implode quicker due to oil contamination and eventual premature wear.

Trust me there is no insecurity here. I know what I got. What I see. But, I think you guys are the guru's and this is you guy's world and I think it's well deserved.

Well that's all that matters. If it works for you, so be it. ;)

hello mis-information! delta dash cannot change ANYTHING in the ECU, just boost,timing,fueling ACROSS THE BOARD!

meanwhile with the utec you can change those things at load/rpm intervals.


DD != UTEC.

Yeah, we covered it. This has been beaten to death... again. ;)

and again and again :)

Well from someone (me) who is neither a rocket scientist or a mechanic, but rather an enthusiast who likes to DRIVE rather than tinker...I have gathered from this thread that (at this time) that Ecutek is MY best option and probably the best oiption for others in my boat. I want a plug and play solution that is trouble free. Since my technical knowledge is limited in this respect, my IMPRESSION of each product (which could be wrong in fact) but it is the impression I'm getting is the People who are throwing around a lot of numbers and people interested in ABSOLUTE Peak HP are endorsing UTEC as well as those BIAS ones that sell it. On the other hand, Ecutek' is giving me an impression that it is a solution that is more "user friendly" and perhaps more reliable over the long haul. (Just impressions here). So wheather wrong or right, based on this thread I'm strongly leaning towatrd Ecutek.

I'm as pro UTEC and TurboXS as possible.

But even I can tell you, as would TurboXS, that the UTEC is defineately not a product for you based on what you just said.

A flash is defineately something that would suit you better.

^^ Exactly. But from what I have gathered from the thread thus far all the UTEC zealots are very onesided against Ekutek. Are these two products THAT much different?

I don't really think that UTEC users are really against the DeltaECU. They just happen to be two different types of modifiers. I think that the DeltaECU users are more of a set and forget crowd. The UTEC crowd is probably more of the never done type (Jorge). When I'm done I probably won't be done. Of course there will be the exceptions to the rule. The UTEC user that looking for the stage setup and the DeltaECU folks that doesn't mind a visit to the tuner every four or five months for the next level of modifications.

I think its basicly different strokes for different folks. Some like utec and the openess it gives you. Others like ecutek/accessecu... some like full stand alones. I like the people that go with both reflash and utec... best of both worlds, no? :lol:

You do realize that you can re-scale the knock sensor rpm ranges with ECUtek so that it listens to the sensor even at high rpm? All the way out to 8000rpm if you want and higher. Sensitivity is also programmable.

DeltaECU is a pretty amazing tool, I'll have to post some screenshots when I get a chance this week.

Ya, but isnt there a down side to running it higher? I know the jdm stis run it higher then the wrx does...

As of what revision of the flash2k2 software has sensativity been adjustable, and what ROM file is that for?

Ozy:

If you have the patience, wait another month for the Cobb AccessPort. With the limited mods you spoke of, a Cobb stage 2 map seems right up your alley. Cobb has a great reputation for making good, safe, no hassle power gains for lightly modded WRX's.

Ecutek sounds cool to me, my buddy has it and likes it.

My bad on the misinformation on the deltaECU or whatever, but if that is deltaDash that is the laptop software my tuner is selling for 300 bucks then it seems fine. I would rather have the tuner do the hardcore stuff anyways so I don't blow up my motor trying to make more power. I will have to invest most of my time into my job so I will leave it to the pros to make my car go fast :p
Up to 252hp on a dyno dynamics so far. Next comes the built motor and the serious crap once I get some finances :)
