I just purchased the UTEC and I'm having trouble understanding the ABC. What does it do? I know it is supposed to allow more boost than stock but what if I don't use it? With a stock WRX and a UTEC with no ABC, it is just basically still stock, right? My other question is what happens if you put the ABC on and just crank it all the way open? The UTEC is what determines your boost, right?

Not sure if you already got an answer. I installed UTEC this week with the ABC. My understanding is the ABC will allow you to tune to higher (overall) boost levels. The UTEC can take advantage of this and control how the boost ramps up to this maximum.

After I install the UTEC and the ABC I had the ABC fully turned down. My boost was maxing out to .08MPas (before that it would go to .095MPas). Sorry for not doing PSI but my boost gage is in MPascals and I need to look up the conversions. I turned the ABC up to give me back my stock boost (about 3 full turns). I then tuned it a little higher which made a big difference in how the car feels.

I just got on here to see if I can find any threads on how to tune the UTEC to improve performance overall. Good luck.

as its name, its an atmospheric boost controller. its used to
compensate for different weather and atmospheric conditions..
for example, if you live in chicago like me and take the car
up in the mountains, the boost will not go up high enough
to where its suppose to... so i can dial in the correct psi. or
vise versa. you need a boost controller to do this.

its a real simple and easy to use unit which i think is a great
thing to have on the utec cause for winter gas i just tune it
down about 1/4 of a turn and during the summer back up 1/4. :p

So, is this something that is adjusted from the Utec or can you just reach in and do it? I looked at my ABC, and saw the + and - but it didnt look like it could be adjusted.

Right now I got my car going and it seems I am only getting like 10 psi in 1st gear. Then it hits some type of cut. I only have a basic map on it....will this go away when I get the Stage 4+ map on it?

I've been doing some research on the Turboxs stuff and have decided to go that route myself.
What I understand the ABC or auxillary boost controller is to hold higher boost pressures than the UTEC can do electronically. The ABC needs to be adjusted once it is in your car that's why they suggest a boost gauge. I wouldn't use the UTEC without one, you won't be getting the full benefit of the "stage" from Turboxs.

I believe the "basic" stage that you speak of is like the stock version. Shouldn't you be running at least the stage 1 program?

Check out their site: Lots more info there.

I'll be getting my Utec this coming Monday if all goes well with UPS. I just got through installing the up-pipe and the down-pipe/stealth exhaust system that utilizes the stock muffler section. The system rocks!!! I have nothing to compare it too however, the car pulls especially hard from 4500 through redline, like freeway passing.

cool, thanks for the reply. I actually put on a Blitz muffler section and now I am able to boost to 14-15psi. before the cut. WOW!!!

I should be Down loading a stage 4 map soon, then getting tuned. That way I'll be back to my normal status. I just finished switching from another product.

Thaks for the info guys,

Does anyone know the conversion of MPa to PSI. I know it's a picky thing but would like to be able to do unitl I put a PSI boost gauge in. Thanks

If I remember correctly 14.7 lbs./sq.in = 1013.25 hPa(hectopascals)

This is at sea level pressure on a standard day.

I'm not sure how mPa converts to hPa. sorry

Hey found this awsome tool!!!

Now you can find any pressure measurment.
I would change the significant figures to about 6 to get more of an accurate conversion.

Pressure Conversion Calculator (http://www.ex.ac.uk/cimt/dictunit/ccpress.htm)

Great conversion table. Thanks
