I have recently been noticing the car really struggles at idle on occasion. The wideband will read full lean (I have the AEM) and the car will drop to around 600rpm and stay there and almost seem as if the car is about to stall, but eventually after 6-8 seconds it fights its way back up. The weather has gotten considerably colder here in the past few days, same time the problem started occurring, is this weather related?

Can anything be done on my tune to remedy this?

Thank You.

 

Bumping the idle timing, bumping the ISCV a little will all help. My lappy died and I dont have a working version of 1.30 on this computer. I will have it out first thing tomorrow.

 

Oh score! Thanks a bunch JB. Is the idle timing the area at 0-1000rpm and 0 - 40 load cells? Where it was suggested to up it to 7*? I haven't done anything, I'm just asking.

 

yea

 

I ripped out the entire idle control system and blocked the bypass ports on my car, never happier. Choppy when it's cold but idles at 850 solid set once via BISS. Not gonna buy a $375 stepper for a crappy designed system
