Yeah I know I'm about to start a war.

Who has the most users.
Who has the most/best support.
Is there pre-made maps for either.
Price wise looks like Hydra would be the winer.
And last what separates the two from each other or what makes one better than the other.
(If you have any other questions please ADD them)

Now I know that UTEC, ECUTEK, AND AP users are going to suggest to just use your respective EM system, however they all have some thing I don't like, so I'm looking for some thing different.

Two words:
Phil Grabow
or
Element Tuning

With AEMS you are nearly on your own (same goes for Motec, Haltec, TEC3, ...). I think we are up to around 100 Element Hydra users now. Setting up a stand alone management system is not a walk in the park. It's damn hard. You can't imagine how many things you totally take for granted with the stock ECU. Phil doesn't have all the answers, but he has put together the Hydra with a 'gifted' level of programming and trouble shooting.

Someday, when I'm retired, I'll try to completely program a stand alone from scratch. Until then, having Phil dedicate a year and half of his life to working out most of the bugs for me, well, I'm grateful.

Oh yeah.....read more buddy!! Your question is waaaaayyyyyyy to general for this crowd. They'll make you wish never bought a Subaru.

BTW mistaboosta not to be rude but if your the same person on the AEM forums you were explained there that the EMS was designed for US SPEC WRX not EURO SPEC. So please do not post that the EMS does not work and its corrupt.

Right now I'm in Las Vegas, in MID march I'll be moving to California, Pasadena area...as for mods I only have DP, and after cat HKS, and not sure what I want to add as of yet, however AEM or HYDRA should give me any mod options I wish to get in the near future. I also haven’t the slightest idea on how to tune it, and will have to be done at a shop.

Any Hydra Users out there ?

The real problem is that there hasn't been quite enough time for the (Element Tuning version) Hydra yet. I think that given more time it will prove to be the better system. Once the Phil G. Roadshow is in full swing and there are plenty of tuners up to speed with plenty of experience on the Hydra it will be very happy days for us Hydra owners (not that they aren't already for those of us who have them).

IMO the AEM is junk. Every car I've tuned an aem on has always had various ecu quirks, only connects to the software when it wants to, and has a tendency to just flake out in general. I personally would wait for the autronic sm4 over either of these systems. Not only is it superior hardware, its software is incredible and super easy to use.

Can the AEM control AVCS now? As I recall, this was not available in earlier releases of AEM for the STi. Hydra has always had this capability.

I believe the 30-1070 box can control it, but the STi uses two signals instead of one like the RSX uses, you may need and amplifier to split the signal. the 1070 has one PWM output that is mapable.

the AEM has all of the hardware to control all of this stuff, its just a matter of unleashing the right software to do it.

AEM is not junk, its just doesn't work well on 6 cylinder cars like supras. We've never had a problem with the WRX's and Honda's we done with them. their software has come a long way over the past couple years and there are fewer and fewer issues with each update. for the money its a very respectable unit.

I've never really heard of any Supra owners complain about it. Matt Scranton said he's never had any issues with it on his drag cars or his Supra.

I'm trying to figure out if I want the AEM or the Hydra too, I'm leaning towards Hydra for its AVCS control. Any updates on the AEM AVCS yet?

I haven't heard of any. I have only heard (and it very well could be wrong) that AEM is still not happy with the setup thanks to the DBW throttle on the STi.

The AEM is a solid system, and their base map for the WRX is actually quite good now. I've used the AEM on my old Integra, on my current WRX, and on a company Evo. It takes some reading to figure out all the settings, but if you're tuning your own car you should really do at least that much homework anyway. The Hydra certainly seems to have a bigger fanbase on here, but the AEM has the support of a huge community of users on different platforms, and their knowledge is a big help as well.

I believe AEM claims it actually shares no hardware with the GEMS, that the only similarity is that the software was adapted from GEMS originally. I suspect it's a big load of crap though, and they have to say that for contractual/licensing reasons... I can't imagine AEM suddenly went from making aluminum intakes and cam geard to fully engineering an engine management system.

Below is something that can be found by simply search the AEM Forums. This was posted by an AEM Employee.
AEM partnered with GEMS to design a new EMS unit called the AEM15. The design is all new but it does share the PC interface software found on the GEMS units (or at least it started out that way, now it's very different). All of the EMS hardware is designed and manufactured in the US by AEM. In fact, we sell finished EMS's to GEMS which is the European distributor for the AEM EMS.

I can 100% promise you that the current AEM EMS product is not a GEMS unit in any way. I worked with AEM to get the first WRX going on a 1010 unit by hard wiring it into my 02 harness. JP & Tom & I spent many hours on the phone making it happen. they design & layout the boards IN HOUSE and have a 3rd party manufacture the circut boards. They have test benches that simulate all the inputs & outputs from any number of makes of car & use that to add new features & outputs, ect.

I am 100% satisfied with my AEM. In fact i am running my car on a box without a serial number, it was the 2nd pre-prodution box made (my reward for helping them R&D)

Very hard to tell.
Who has the most/best support.
If you get an Element Tuning EMS (Hydra) from any distributor, support from Phil @ Element will be good.

I have no idea what AEM's support is like as far as calling and getting someone on the phone within an hour to solve a problem, etc.
Is there pre-made maps for either.
Yes
Price wise looks like Hydra would be the winer.
Barely
And last what separates the two from each other or what makes one better than the other.
Very little of great significance from what I can tell.

The AEM is great in the aspect of the number of extra inputs and outputs you have... something that the Hydra lacks. Hydra is good for plug and play but the EMS offers SO much more expandability over the hydra.

AEM has come a long way with developing their boxes over the past couple of years, as I'm sure Element will come along with the hydra. It takes time to find flaws and bugs in the system.

As far as AEM tech support, its not wonderful, but they are decent, but chances of finding someone else to help trouble shoot things is pretty easy. Right now if you have a problem with a hydra the only person you can really get a substantial amount of help from is Phil, If your EMS goes haywire and you can bet there is someone within a days drive that can sort things out for you. Just cause its not common in the subaru market doesn't mean that its not widely supported.

I'd suspect the reason why the EMS isn't more competitive in the subaru market is because its priced its self way above the alternatives.

Hydra has:

1. 8 peak and hold injector drivers (4A peak, 1A hold current). Unused drivers can be used for many other output functions, some even pulse modulated.
2. 8 igniter signal outputs.
3. 11 1A switch to ground PWM outputs.
4. 3 1A switch to power PWM outputs.
5. 1 2-channel reversible TGV driver (STI enhanced board)
6. 1 4-channel reversible stepper motor driver.
7. 2 dedicated circuit opening (shutoff relay) easy connect outputs.
8. 1 2-channel reversible drive-by-wire solenoid output (STI enhanced board)
9. 6 multi-function inputs for requests and switches

PLUS more in the way of independent pwm fuel pump control, Honda RS232 instrument and climate control data bus, L1H1 heater drivers, etc.

Lacking in outputs? In the bizarro-world maybe ;)

Also I want to say that Andrew (US rep for Hydra) has for me been super helpful. I spoke with him will after quiting time on a problem. And he called back later that night to verify everything was good. And then a week later he followed up as well. So there are at least two Hydra gurus that are willing to go that extra mile.

Brad -

Just what "problems" is Matt Scranton having with the EMS? He just went 6.81 at 217.28 this weekend at the Topeka NHRA event...the data logs from that 217 MPH run indicates he was off the throttle for over 1 second trying to pedal the car just after the launch.

If Matt Scranton is having problems - keep them coming! I would hate to see what would have happened if he was able to stay in it the whole run.

If anyone has any questions regarding the AEM EMS, the aempower electronics forum has an abundance of information.

I hear AEM is going to be similiar to a stand alone but work piggy back to the stock STi ecu. Can you elaborate?

The resolution of AEM maps is low compared to the Hydra. If you are pushing greater than 3 atmospheres of pressure like Phil's car is, I just don't see 16 X 16 cutting it. I'm not saying it can't be done, but it is more difficult than with 32 X 32 fuel and spark.

I think we will see more 'versatility' from the Hydra soon. One thing that is not appreciated when you just list inputs and outputs is just how many of those are already in use to work with stock sensors and actuators. The Hydra has only been out since late Feb. There are plans for more 'user' inputs (like EGT and anti-lag) and the software is changing slowly for the better. I know Phil has anti-lag running on his car, and I've been working with him on water injection. The whole system is coming along under Phil.

I still feel the way I did back in Feb, Phil and Element are the best things happening in EM right now. AEM is a manufacturer with zippo Subaru tuning experience (much like Andrew and Quantum). Phil at the very least is a great sounding board for tuning questions (of which I have a ton) and at his best, he has tuned more Subarus than probably anyone (some of which are record holders).

I would not buy a Hydra for the hardware or the software, I'd buy it for the wetware, which is Phil and Element.

Devin@AEM

As for the STI specific questions - we are still a while out on the EMS for that application.

The resolution of AEM maps is low compared to the Hydra. If you are pushing greater than 3 atmospheres of pressure like Phil's car is, I just don't see 16 X 16 cutting it...

You are incorrect with regards to your 16 X 16 resolution number for the AEM. Not to mention, when you pressure comp tune with the AEM, the number of actual resolution points grows in the tens of thousands.

AEM is a manufacturer with zippo Subaru tuning experience (much like Andrew and Quantum)...

Since when is a Subaru motor not a 4 stroke gas engine? Is there something I am missing? Flux capacitor? Nuclear reactor? It is pretty bold and arrogant for you use the word "zippo".

I guess you didn't take into consideration the size of our staff and how many of us have been tuning for many, many years (Subaru powered cars included).

Both ECU's are excellent and very powerful allowing you to do remarkable things on their intended application. That being said I'd rather tune a Hydra anyday over the AEM just because the software is much easier and faster to work with. The datalogging with Excel exporting is just darn nifty and a godsend when street tuning. Lastly the base maps provided by Phil At Element Tuning are worlds better but if tuned properly that really doesn't matter. Basically you can't go wrong with either. It comes down to pricing (Hydra has the edge there) and who is around for tuning in your area.

I can't find any information on the resolution from AEM's website, but I believe you are right.

I think I'll have to report back to this thread after my experiences with both. I'm getting a hydra for my RS, and my brother is getting an AEM for his 86 Mustang. We are both going turbo so it'll be interesting to see the differences in how the systems behave, and how easy they are to tune.

of course you don't see a lot of tuners who manually tune each load point on a 1024-cell map either. Typically you fine-tune several critical locations and interpolate between them. The in-between points are useful if your car has some erratic response in an individual location though. Not going to affect your max power or anything, might be smoother depending on how skilled your tuner is and how many dozens of hours you want to pay him to work on your map.

As advanced as both these systems are, I would think the best one would be the em where you can get vendor/tuner support. If you don't have that support with either, I'd say Hydra since you can self tune the EM with instructoins on www.elementtuning.com

True, and Phil has spent dozens of hours tuning all over the map. I've poured over another couple of dozen. Autotune and interpolation helps fill in. Smooth is one way to put it, precise is another.

Out of sheer morbid curiosity, have you actually used any EMS aside from the Hydra?

I can understand enthusiasm for a great system though. It's clearly a good setup, mostly because of the time and energy Phil and others have put into tuning it.

from what ive read, i could be wrong on some points but the hydra seems to be very similar to the utec but with more options...meaning the data input to tune the vehicle uses the excel style and u have to manually tune each box...ive been talking to an aem tuner and he showed me how he tunes his cars...he calls it boost compensation...basically using a 2d map with another 3d map tuning 0-99% throttle with the touch of a graph and doing the same with full throttle...i dont like the hydra from what ive read b/c of the manual inputs throughout the rpm range....the ems from what ive been told...if u fix one thing on the rpm's u have an option on either having everything follow it or just tuning that particular rpm...this is good for partial throttle tuning when u dont want to manually put in everything from 0 rpms to before full boost rpms...this also goes for throttle position...also...one question i want answered for hydra...does it have uego? basically it tunes itself to the weather, which is what aem does...does hydra have that capability b/c i dont want to have a map selector and have to get it tuned accordingly for the weather...not to mention i have had an aem wideband gauge with a chipped ecu...if it wasnt for that gauge i woulda blown my motor the 1st day ;] my vote is for aem based on things ive read and the conclusion of my opinion

from what ive read, i could be wrong on some points but the hydra seems to be very similar to the utec but with more options...meaning the data input to tune the vehicle uses the excel style and u have to manually tune each box...ive been talking to an aem tuner and he showed me how he tunes his cars...he calls it boost compensation...basically using a 2d map with another 3d map tuning 0-99% throttle with the touch of a graph and doing the same with full throttle...i dont like the hydra from what ive read b/c of the manual inputs throughout the rpm range....the ems from what ive been told...if u fix one thing on the rpm's u have an option on either having everything follow it or just tuning that particular rpm...this is good for partial throttle tuning when u dont want to manually put in everything from 0 rpms to before full boost rpms...this also goes for throttle position...also...one question i want answered for hydra...does it have uego? basically it tunes itself to the weather, which is what aem does...does hydra have that capability b/c i dont want to have a map selector and have to get it tuned accordingly for the weather...not to mention i have had an aem wideband gauge with a chipped ecu...if it wasnt for that gauge i woulda blown my motor the 1st day ;] my vote is for aem based on things ive read and the conclusion of my opinion

Unfortunately a lot of what you heard about the Hydra is incorrect. The Hydra is not anything like a UTEC, it's instead very similar to MOTEC. You have fuel and spark maps that approach 1100 load sites. While each load cell can be fine tuned to precisely control AFR, you can also highlight multiple cells and make global changes. While this may sound daunting it’s very predictable and typically tuning higher boost levels can be extrapolated from what’s done a lower levels:

2D tuning is never as precise a 3D tuning. It’s easier for novices but it will not allow for finite control. You can see in this fuel map how much of what happens at low boost translates into high boost. Also when looking at a 3D map you can see where your engine is efficient and where it is not. Seeing this VE change is often very helpful when picking cams, deciding on a head package, or even picking a turbocharger.

The Hydra also has a wideband AFR readings, programmable closed loop fuel control based on an almost 1100 cell target map, RPM targets, and has AutoTuning to more quickly dial in a new setup. I use this on almost every car I tune as it’s substantially faster tuning than any human can be. Once it’s honed it I’ll fine tune by hand. It also has the capability of using the OEM narrow band for closed loop operation when targeting 14.7:1

Not to sound like I am intruding, but I have a few questions.

1. Which one is easier to street tune, as there is ZERO Subaru tuners near me?

2. Which is easier for a Novice to tune? I mean ZERO tuning experience.

3. Can I make it work on a Version 8 motor as I am looking into picking one up?

4. Who has better support?

5. Since I would prefer to run with a wideband, does either have the ability to send the wide band info to the gauge? Or will I have to split the wire, buy a second wideband, etc..?

That's all I can think of at the moment.

Thanks,

Hey Phil, can I trade in my WRX AEM for a Hydra? ;)

Brian,

Unfortunately you've got quite a few things working against you. A motor swap which happens to be one of the most difficult things to sort out, a lack of professional tuners, and lastly no experience.

While we can offer good base maps they are only that, good base maps. Each car requires some tuning, some setups more than others. A Hydra due to tech support and base mapping is going to be the better choice for you but a stand-alone for some one with zero experience is asking alot.

With that said customers of ours that have experience tuning piggy-back systems adapt quickly and absolutely love it. Those with some knowledge and a willingness to learn do well with tech support and guidance. The AutoTune feature really does work very well! Those with zero experience and extensive mods usually try it but end up organizing a few cars for me to tune and fly me in. Those with no experience, no common sense, don't read instructions well, and have no willingness to learn end up selling it :lol:

I hope this helps guide you.

Thanks,
Phil

Thanks for the prompt response. I planned on being able to drive someone later this summer to get it tuned but for the most part it would need to be a, get it running for a while thing and leave it alone aslong as I have no problems with it.

I would pay to fly you in and tune it, but it would definately be cheaper for me to drive somewhere and have it done. As all of the flights here have to be taken from Denver or SLC on a "corporate type jet" and not to many others here are even thinking of a Stand Alone EMS. :furious:

If I could give you some ideas of what I need etc.. would you be able to build a base map that could hold me out for a while until I can drive to SLC, California, or somewhere that has someone that could tune the Hydra?

I would be more then willing to read, read, and read some more until I figured it out, or broke something. I just don't want to waste anyone's time having them tell me what the hell to do.

Thanks again,
Brian

I know this guy in Smyrna, he can tune your AEM since it couldnt be taken care of at that other shop.

While I know Dan can tune AEM's...I am more than qualified enough to tune my own car...thanks.

I'll be over for fun times when i get it up and running tho...I might need some dyno time...;)
