Hi folks, i just bought an Apexi AVCR for my 20VT.
In order not to do some bullshit while wireing it, i am looking for some pictures of the parts wired : solenoïd, pressure sensor and air filter.

If you have some good advices to give to a dummy, i would be very happy

Do you have the instruction manual for it? It explains in there how you should connect it up, and there's a guide in the relevant section of the forum.

I have recorded a copy of the ECU wiring, and i found a "how to guide" for a Subaru STI8 in french.

I am looking for some pictures of the solenoïd, pressure sensor & air filter fitted on a coop.

If you have some good parameters advices also.

Cheers !

Sorry, I have no photos but this link might also be useful...
20VT Engine Fuel System (Workshop Manual)

For parameters, you will have to experiment yourself or have it setup on a rolling road (much safer).
Here's are a couple of useful links:

Setup Guide

Thanks barney, i will look at this tonight
cheers !

Hi folks,
finally my avcr has been mounted this sunday.
I have a little problem, since i wired it, i have the injection signal turned on.
i have took the orignal solenoïd off the car, and i have wired the apexi one.

Someone told me that i had to leave the original solenoïd wired to the ECU.
Is he right ?

cheers

Yes, otherwise the injector light will come on.

The problem is fixed... thank you mattB.
I have another question : is it possible to limit the overboost in the mode A & B ?

Preventing or achieving a certain amount of overboost is down to tuning your Apexi and depends on whether or not you are using the self-learn feature or manually configuring it. There is a start duty setting that can be applied for each gear to adjust overboost levels. (Theoretically, self learn should sort everything out for you!)

At the moment, I'm using the self-learn function with the first two gears excluded. Might try an all manual configuration when I have more time.

thx for your answer. I will try the self lear mode to see what it looks like.

Cheers barney

Have another read of the setup guide I gave a link for above. It gives clear instructions on how to get self-learn working. Please be careful though! Tweeking these things can be a major distraction whilst driving. I would strongly recommend waiting until the roads are quiet or even better, get a friend to help.

I found a guide on the forum which gave us some settings. Check this out

i used the same settings for the boost/duty and for the Ne points

I can't open those links I'm afraid but have to say I'd be cautious about just entering somebody else's settings unless the car in question was nearly identical to your own.

Iirc, my Ne points start around 3000 and increment by 500. This should be ok if you are running a bigger turbo and do not have a raised rev limit.

To set duty, find a long straight road with no traffic. Set target boost to 1.2 bar. Put in a low boost duty of around 40%. Set your Apexi to monitor boost and then set it to latch peak values.
Go gently through 1st and 2nd gears and when safe to do so, change to 3rd and hit the throttle hard! With foot flat down, keep on the power right up through the rev range to about 6500rpm. Then back off, drive gently and park up.
Check the indicated peak boost value. It will probably be lower than 1.2bar. Repeat the above procedure but with a slightly higher duty setting. Keep trying until your peak boost reading is 1.2bar. If you have self learning enabled, the AVCR will take then over.

Now let's say you want to run 1.5bar. You can have two maps (A & B). Switch to the other map and start again but with a target boost of 1.5. You should be able to use your last duty setting plus a few more percent as a starting point.

Almost forgot, have you setup your gear ratios?

Thank you for your answer.
I'm running a standard turbo for the moment, but i will receive my hybrid turbo soon.

For the Ne-Point as it is written in the links above, i have set the 1st NE POINT at 1500. then 2000, 2500, 3000, 3500, 4000, 5000, and 6000.

Learn Gear : i have turned it off for the moment.
