Tuning Idle on SD tune

zeekracing · 07-02-2009, 03:54 PM

I'm trying to convert to speed denisty. My car runs a lot better without my maf but the car will not idle at all. I have to keep my foot on the gas pedal. I tried tuning the bottom of the ve table and messing with the idle airflow. Nothing has helped. I must be overlooking something. Can someone put me on the right track? My afr is 11.5 way rich with my foot on the gas at 1100rpm.

Post up a log and your tune. Also your modifications.

What injectors ? My 60s idled ok but rich when fired up the car in 3bar sd. I got them to idle in the proper range now but am rich on decel. Always something!

Sounds like you aren't tuning the RIGHT VE table... Unless you are running the HPTuner's 2bar SD OS (yes it works very well for 1-bar apps too since it puts you back on the main VE/spark tables) then you are running off of the SECONDARY VE and LOW OCTANE tables. If you are changing the Primary VE and leaving the secondary then that is your issue.

The first thing to check is IAC count.At warm idle I like it at 30-60.That will affect alot of things.
