adding will lean, decreasing will richen. example, 12.0 down to 11.0 will richen. 10.0 up to 12.0 will lean. good luck!

Danger, Will Robinson! Danger!

1. How do you know if you are running "too rich?"

2. Familiarize yourself with the basic concepts of air-fuel ratios before moving on.

A basic user guide to ECUFlash has been posted that I think you will find very helpful.

Spend the time at least on the tutorial, and search the forums and might be a good idea to check out AMS tuning tips sticky on their subforum of evom.
