I am making some progress on the tuning of car finally after the change over from 8d to $58.

The area where I could use some advise is I am getting a stall when I press in clutch when slowing to say make a turn. I can see in the datalog that the wb is showing an af ration of 20 which I believe is because of DE because the throttle is closed.

Would the problem be in the DE section? What would be the best place to start?



Most of my steady state af is 14.7.

Thanks
Tom

edit: If you watch the tach when you press in the clutch it drops right down to 400ish bounces up a bit to try and recover then dies.

 

I was also thinking if there was an equivalent of a throttle follower in $58 that might help.

Is there one in $58 called something different?

I have my IAC steps set to 0 and it will idle solid, however, if i blip the throttle the IAC goes up and takes a while to come down while doing this it surges slightly until the IAC steps get down to 0 then it is stable.

Help on these two items would get me a long way to getting it drivable.

Thanks
Again

 

Anyone?

 

What is the IAC doing?.
Too low of min idle speed can do what you're seeing.

If it hitting 400 RPM, you might try increasing the min P/S rpm. Been a while but I think that's what it's titled.

 

My idle is set for 750 in the chip.

Yes I am hitting as low as 400 rpm before the rpm's bounce up then stalls.

min p/s? what is P/S refering to Power steering Stall?
