VPC and S-AFC?

JW, but he has the old style SAFC, which does not go beyond 30%, so doubt that he will be able to compensate enough .

I was just guessing, turn AFC -30%, gain & idle knobs -12%, perhaps it will just idle? I dont know, like I said it's just guessing. Interesting to find out tho how the fuel trims will be able to adjust itself if it's still within the ECU *window*.

I'll let you guys know how it works out.

Ok, took her to the track tonight. Best was 14.10@103 @ 14 psi with a 2.4 60 foot. Yes I was very dissapointed. So I go pit in all pissed and $hit, and i pop the hood, then I notice this loud hissing noise and I realized there was a BIG vacuum leak somewhere, also I was wondering why my car couldn't idle. So, I realized I was running with a missing biss screw! And I was checking all the piping connections and the inlet side of the IC the clamp was past the bead, so there was defineately a leak there too. Thank God I have a VPC or it would be pretty much impossible to drive it home with such a big vacuum leak.

My settings now are on pump gas VPC respose 5 o clock, idle 7 o clock, gain. 8 o clock. AFC is 800 -23%, 2400 -22% 5600 -21% 7200 -19% Still runs pretty rich, but I don't have an EGT gauge, so I'm relying on the led air/fuel meter, so I don't wanna go too crazy leaning out.

I have been reading this thread and it seems that people have there vpc set pretty much the same on the same setup as others.

My problem is that I have a stock injectors stock chip in the vpc.
TR is 12-1 oclock Gain is 2 oclock idle is 12 oclock

Running like this is good the idle is great egt stay at around 1250 -1320 when WOT.

Now if I put the TR at 5 oclock like every one else my car just cuts out when I get on it. Any one know why this would be? I am seeing that I could cut my gain back a few clicks and maybe run it a little leaner and watch my EGT.

I was looking at getting a GCC but it seems the new S-AFC would be a better choice. The turbo is a Big 16g ported and clipped.

Thanks for any info.

a little off topic here,has any one try using 2 bar map sensor GM to work with the VPC, my sensor is shot needs to be change and the price for a new one is $155.00 compare it to GM sensor.

I believe that you need to use 3 bar sensor. 2 bar will only give you 15psi or so (atm pressure takes care of the 1st bar).
