Default unichip - ECU - what to get/what to expect

ok, im as smart as a sack of hammers when it comes to this...im new to the turbo deal...im looking for a unichip and dont know what to look for...i only intend on installing a unichip and k&n filter

questions:

1. difference between ecu and unichip?...after much reading on this forum i figured the unichip just ties into the ecu

2. what company should i purchase the unichip from?...who is better...any thoughts

3. will i need a boost gauge or any other gauges?

4. I want to run 15 psi in ALL gears at all times...will the unichip be programmed to do that or is it adjustable to where you set the psi you want to run?

5. What hp will i be running with a unichip and k&n filter and what 1/4 mile times should i expect?

6. What is the going rate for a unichip?...im looking for a plu-n-play deal for easy install/removal for when servicing is needed

7. what all does the unichip do to create more hp

any help is greatly appreciated

the unichip works in concert with the stock ECU. The ECU can still raise and lower timing based on sensor input etc.

the unichip primarly raises boost and optimizes the timing/fuel maps to make everything work properly.

your best bets are trey cobb or turbo XS.

personally, I wouldn't reccomend just ordering one, I would get it dyno tuned by a pro. TurboXS and Cobb I believe both can do dyno tuning.

one more time for the people in the back row...

Information = Power = Speed

before your first mod...buy the tools so you can diagnose anything that may go wrong. Unless your frist mod is stickers...but those are free HP

Scan Tool - Guages (EGT, Boost, ect) - Knock Link

Then you can start messing with the engine...

i thought that one of the plus sides of getting a unichip over a mbc was that you didnt need to tune it...i dont know of anywhere near me in atlanta that does that...is it really needed...i thought a unichip was safe to just plug right in...also, if you do get it tuned, what about when you take it in for service and you unplug the unichip...do you need to get it retuned once you put it back on...that makes the "plug-n-play" concept not as good to me...

It comes with a boost controller...and you can control THE BOOST...you just can't change the map on it...you have to have it 'retuned'...if you want something where you can control the map...then tec2 - halitec or something like that is the solution...

and even if its all done for you....you still need all that information to know whats going on in the car...last time I checked the space shuttle had more then a spedometer on it

Edit: Unless you live next door to Cobb or TurboXS who has a dyno on site and can diagnose problems for you...

I believe the Stage 1 unichip from TurboXs will be mapped to the mods included in the Stage 1 kit....K&N filter, TurboXs cat-back, intake silencer mod, and probably 91-93 octane gas. If you're close to this, I think you'd be all right. A WRX with just a K&N for instance (like mine) should run just fine....I believe....the gauges are just for piece of mind.....peace

Very valid...I still dont have quite the confedence to do just anything...but my confidence has sky rocketed from 1. talking to people 2. reading information 3. getting my hands dirty.

I relate it when I first got a computer (back in 1987 ) ... scared as hell to even touch the thing...but wanted to know whats going on in that...and how to make it better...bought a book...talked to some people...and soon realized...my fears were just what I did not know about.

This forum has given me a lot of good (some bad) information. But the good WAY out weights the bad. If anything...this board has opened my eyes to options.

Happy Tuning

I have the TurboXS unichip and I`m very happy with it.

Yes, you need gauges. Even if you buy the cheapy autometer ones. You need gauges. I would recommend at least boost and egt then your choice of fuel pressure or maybe oil pressure.

I would also suggest a knocklink.

In regards to the boost being adjustable. In reality it doesn`t come that way. The unichip is setup with a dyno`d map and preset boost levels, tapering down from a high ~16.5psi to ~12psi at high rpm.

If you want to set you're own boost levels, I`m pretty sure you do that at your own risk. Mark and I`m sure Trey don`t want to be responsible for people grenading their motors because they(customers) don`t know what they are doing.

I also would recommend going to TurboXS, if that is the company you choose, and have Mark custom dyno the chip for your car. I`m sure everyone will recommend some dyno time.

My setup is really just plug-n-play. I don`t fool with any settings.

hey, bill

thats really all i want is plug-n-play...i surely dont want to mess with boost levels myself...i just didnt know that the unichip did all that on its own...does the turboxs unichip raise the boost levels in 1-2 gears as well...i assume it does...i think im gonna get the turboxs unichip...i emailed him for help and what not...

peace out

I got a MBC from Dawes for 30.00 to hold me over until I can get a UNIChip. The waiting list is very long. Its real easy to install and set. I currently have mine set to 15lbs. (Spikes to 16 in 4th gear) It holds the boost through the entire rpm range bypassing the ECU's control of boost. Just running at stock boost the car is much quicker.

I forget what I`m running for boost in 1&2 gear. I`ll check tomorrow and let you know. It is definitely more then stock.

I just installed my Defi gauges so this will give me a chance to play with the play-back feature.

Just so you know Mark gets over 100 emails a day so it might take a day or two for him to get back to you. You might try calling he's almost always there and if not he's doing dyno work.

just to make sure all the people asking questions are clear on this...

the Unichip is a single brand name product made by Dastek and mainly pushed by APS (Air Power Systems) of Australia. Two vendors here in the United States have set themselves up as vendors for the APS Unichip and they are www.cobbtuning.com and www.turboXS.com

The unichip from both vendors is physically the same. It's just a programmable box. They will come with slightly different but probably equally as good 'maps' which are the parameters set by the respective tuners for certain car setups.

TurboXS currently has a plug-n-play system but Cobb has also announced it too would have stock maps for Plug-n-play ability.

cheers

Should the Stock ECU be re-flashed before adding the UNICHIP?

Gossamer-monster: Why does one need gauges if they have a unichip. I understand Turboxs chip peaks at about l6.5psi and is tuned very conservatively to make sure there is no detenation or running problems. I have one on order(I have a Cobb cat-back and K&N as only mods). I am paying for Mark's skill at tuning the chip for a very conservative and reliable power gain with proper fuel/air mixture at all times. I don't see the need for guages for the stock set-up, so why would one be needed for the unichip?

It`s always better safe then sorry. You really need to know if something is wrong with your car. It could be something completely unrelated to the Unichip, but if it goes undetected it could cause problems. Ask Mark he`ll tell you the same.

My car is a "stock" TurboXS unichip setup but I wouldn`t drive it without the info from my gauges.

And nhluhr the Unichip TurboXS is selling has nothing to do with APS. APS' name on a unichip is the same as saying a TurboXS unichip. They are all made by Dastek a South Africian company.

APS customizes their own and TurboXS has their own methods. The hardware is the same but that is the end of the similarities.

Well, I think if I was using an adjustable boost controller I would get a boost guage, etc. but the levels of boost used by Mark just don't seem to warrant the hassle and cost of guages. Guess I'll just go with it sans guages. I don't really like any of the aftermarket guage set-ups, not to mention the hassle and expense of installing them.

I'm with gossamer_monster on this one. I think one of the first things that should be done prior to modification is the fitting of the appropriate guages. Basically you know what you the car is doing before and after. Also (mainly) for the detection of anything that might be amiss. Perhaps a boost controller that is not controlling boost, higher than normal EGTs. Unless you have some way of monitoring this then you're not gonna know if something is different from the norm. Not everybody has a MoTeC with datalogging

Ok, just thought I had missed something.

I don`t have any cel issues. So it`s a good possibility you won`t either.

Hello...
I am a member of another board. We recently have also started to use the Unichip.We currently have 2 people with the Unichip installed. One of them was able to get 40whp and 42lb feet fo torque out of his Accord V6. From what I have read the WRX also gets great results.

If you go to www.theracersgroup.com

I believe they are the main distributor for the Unichip. On their site they show all authorized dealers for the Unichip. They also show how it works and specifics of it all. Hope this info helps out and answers some questions.

So for anyone in the Bay Area that is looking to get the Unichip, The Racers Group is located at Sears Point Raceway.
