Default AVCR Settings

Im going to get my friend to install and set up my AVCR.

He's done a mint job on his evo, but said he will the the wiring diagram, which I guess will be this:
http://www.apexi-usa.com/pdfInstallation/45.pdf

and this
http://www.apexi-usa.com/pdfWiring/8.pdf

But I DONT need this do I?
http://www.apexi-usa.com/pdfWiring/2.pdf
As my car is a 2003 WRX STI.


What basic settings should we start with though when setting it up? PM me if you dont want to give away any secrets, lol.

Should we not bother with 1st gear, as I've got a 6 speed box?

I know you can have two settings, is this normally just high boost and low boost? What boost pressures for each do you recommend?

Current Mods:
3" Full de-catted Stainless Exhaust, including up and down pipe
K&N Cold Air Intake
Walbro Fuel Pump
HKS Fuel Pressure Regulator
ECUTek Remap by Scoobyclinic
Dump Valve



Thanks a lot guys

Hi Mate,

You'll need the wiring diagram in the final link not the previous one.

Set your high boost setting for what it's mapped to I would imagine its 1.5 bar tailing of to 1.3? so set for 1.5 max.

You can then have a low setting which could be say 1.2 bar.

You can also have a third setting that would be with the AVCR off which would be actuator pressure usually around 0.7bar I think.

You could also wire in a switch which is an instant scramble mode. So if you are in low boost you just simply press the switch and it gives you a tailor made setting over and above what your low boost is set to. Normally you set this to the higher boost setting. So you can activate your higher boost setting instanty without having to scroll through the menu system to get to the right setting.

The AVCR is THE best boost controller on the market

I'm not too sure what it was mapped at, but I will look at the rolling road graph to see if it says on there.

The switch sounds good!! Would this replace the 3rd setting which you mentioned for off? I'd rather the switch I think. Where is this wired to?

So I need the 2.pdf not the 8.pdf

Thanks a lot

One thing i would do is check the ecu pin out diagram as i wired my AVCR from the same diagram (I have a 04sti) and found after that the speed signal pin is not correct in the apexi diagram. IIRC its the one to the right. Better to get an OEM pin out diagram to double check.
Argee with Daz about how good the controller is.....In winter you can turn the duty down a little and when its hot increase it to get rid of that lathagic feeling. I dont use the scramble function and generally just leave it on high boost setting unless the wife is driving it when i'll turn it to off

For starters always start with lower boost setting than your final target. Duty would ideally be around 40 to start increasing as needed, once the desired level has been reached it will be more straight forward to then work on second boost settings and in gear specific targets.

The switch won't work with the unit switched off.
As far as I can remember the scramble switch was the orange wire.
The switch then just goes to earth.
the 8.pdf is for the classic impreza the 2.pdf is the one you'll need.

Can anyone confirm Linky's point?

Thanks Slowboy for the advice as well.

Daz, what type of switch did you use? Something like EAO | Relays, Switches and Indicators | Switches | Push Button Switches | 4 to 7mm Diameter Cut Out - Low Voltage - Push Button Switches

I'm not sure for your car but for the MY04 sti type uk ECU the pin out for the speed signal is in the wrong position on the apexi website. IIRC the speed signal is the pin out to the right of the one indicated.
It was Andy F who first put me onto this as when i first had the car mapped i had the wire connected to the one on the diagram and we couldn't use the in gear boost settings without a speed signal input.

Get a hold of an OEM pin out diagram and double check.

I hope this helps
Colin

I imagine ours will be the same!

Your right, I will have to try and source a pin out of the oem diagram.

From the 04STi workshop manual, it looks like it is pin 27 on block B (i.e. directly above the pin labelled as ground in the Apexi diagram).
Can anyone confirm?

Anyone Need to know before we do it really.


Also, for settings does this sound about right to start us off Setting it up??
1. You need to set up the NE points to start with, 2500, 3500, 4500, 5500, 6000, 6500, 7000, 7500.

2. set the car settings to 4 4 arrow to the North East.

3. Set the graph scales, speed, boost etc.

4. Set FB speed to 0 and learn gear to X.

5. Ensure the start duty to 0% for all gears.

6. Then set gear judge up, drive along in first, with the AVCR in the Gear Judge menu, you will see the numbers decreasing on the right of the screen. When you get to 2500 rpm in 1st, set the number for that gear, do the same with all the other gears at 2500 rpm.

7. Set desired boost level 1.6 on the AVCR is about 1.56 bar, duty cycle around 63%. Drive in 4th gear at around 2000 rpm, and open the throttle 100% waiting for the boost to build up, get to about 5000 rpm and see what peak boost you made. If it below the 1.6 then raise the duty cycle 1 or 2% and try again, if it above, lower the duty cycle 1 or 2%.
Once the car gets to the correct boost in 4th gear, turn lean gear on in 3rd, 4th and 5th, and go for a hard drive.
This will allow the AVCR to learn the duty cycles accross the RPM range to maintain your desired boost.

8. Once it has done this, the duty cycle in the menu will show ***, as the duty will vary accross the RPM range.

9. You will need to adjust the FB speed if you are getting boost fluctuations, this adjust the response of the boost solenoid.

10. After set the start dutys in 1st to around 8% and see what peak boost you hit, adjust up or down to get the required peak boost level in each gear, repeat for 2nd, 3rd, 4th should be about +1 or +2 and 5th should be something like -1 or -2.

11. Finally go into the duty screen for RPM and lower the duty at 6000 and above a few % to get boost taper at the top end.

not just saying this.. but the car has been mapped to the current setup and boost level.. the AVCR may bring the boost in sooner or run more boost than it is currently mapped for.. if you are lucky the ecu will pull the timing and you will lose a little power.. if you are unlucky you'll damage the engine.

Install it and take it back to who mapped it and get them to set the AVCR up.

Don't set the duty to 63% and go and floor it.. you might have pipe on wrong or your actuator maybe stronger and require less..start at 20% the minimum and try it and then go up slowly in stages..

Thanks Simon.

That what I quoted is actually from an Evo, my friend sent it to me (didnt realise it was for an evo when I posted).

I was under the impression its ok to DIY the avcr? Just its a 3 hours drive to where it got mapped, so quite a way. My mate set his up perfectly on his Evo, so we were going to try it on mine! I think it says the boost on my RR Graph.

Thanks again.

evo engine and ecu are very different to Subaru.

When the car is mapped already it is more important to have it checked / altered for changes to the setup.. as it is mapped to get the most out of the current setup etc..

3hours? round trip you mean?
my mum used to live in Whitby.. the drive from Whitby up over the moors is superb though!

you can match the current boost and the current spool point etc.. but that would be a waste and difficult to be sure it is exact.

lol, maybe 3 hours round trip What was your mum's name? My mum may know her!

Might have to plan a bit more then about fitting the AVCR now, as I thought you just installed it, and just 'set it up'.
As it will obviously cost a bit taking it back to Scooby Clinic. I didn't map it there, it was the previous owner who did.

she may well have know her as she was a bit of a character along with my step dad.. unfortunatly she passed away 2005.. I'll PM you..

it just all gets a bit different when mapped for a setup.. it might be perfectly fine.. but it would be worth checking.

Ok thanks mate. I will email Scoobyclinic and see how much they will charge!


Or might put off installing it until I get my other mods on, then get you to remap the car and set it up properly

worth dropping them an email for sure.

if you have other mods planned then it would be ideal to fit them all at the same time etc..

I wasn't digging for work.. I honestly wouldn't want you to break something
