I can get mine to idle now at 12.0AFR. All I have to do is start the car, wait for it to come off cold idle, and put the mainscale up to +25 and wait a minute for the idle to settle down, then back it down to +10.

I have my low tune settings 400, 800, and 1200 around +10-13 also. That's the only way it will run nice.

With everything zeroed out, it just stalls.

(stock injectors)

BTW: which one of those 3 nipples on top of the TB have a good vacuum source? I'm trying to limit my vacuum T's.

Sounds like you maybe having really similar issues as myself.....

What is your afterstart set to?

I T'd into the BOV hose for the MAP sensor.

Bob is there a way to do some smoothing while at idle to the Freq out? I am not sure but I am seeing some spiky Freq out values and maybe this is why my tune goes to shit really quick, causing the bouncing A/F? The MAT/MAP/RPM/TPS/etc all seem to stay pretty much stable, but the Freq out I have seen go from ~30hz to ~90hz in a sample.

Afterstart set to zero. I'd still like to know if there's a good vacuum source from the 3 nipples on the TB for my boost guage.

You might try setting it to 5%, or more if the car wants it...
My afterstart is set to 15.

Anyone?

RobBeck · 01-23-2006, 04:53 PM

Were more concerned with getting drivability down with injectors than timing control at this point.... it is coming or practically there but I doubt it will be really high on your priority list right off the bat.

do you only have problems at idle?

my car is not currently running, but i used to have a problem at idle, but the worse problem was while cruising. it would buck like crazy going from engine breaking to accelerating but would not let me just cruise. i had to richen everything out like crazy to get it to go back to normal..

an PS.. i am still very interested in getting the timing control working as i like to drive WOT more often anyways, which is where this thing has always kicked ass
