Pebo,

I responded to your PM.

There are 4 idle speed tables and 4 ignition timing tables related to idle speed correction.

From memory (I sold the car 6 months ago), I was not able to alter the idle speed as you suggest. All I managed to do was alter the cold start idle speed.
In March 2013, we released VersaTuner 1.8.5 which exposed the additional idle control tables.

This is a bit old, but i will ask anyway.

I was reading your tune and i have a question about the AFR 10:1 (0.68), what kind of fuel did you use for this ratio? i mean, normal is around 14,7:1, so im a bit confused if you use some ethanol mixture and if this can work just with 95oct?

Tnx

14.7:1 is used at low load for efficiency and low emissions. Richer mixtures like 10:1 are used at high load for charge cooling and knock control, especially in direct injection turbo application.
