post your .msq file that you are using,or email it to me, maybe I can take a look at it and see whats up with your settings. The autotune feature is set for certain perameters only, unless you manually configure it to what you want. Default is like 60kap to 90 kpa, and from 2000 rpm on up to 4000 rpm, or somewhere in those lines. So you need to be actually driving the car to use autoune, and it must be within those settings. Make sure you dont have your EGO settings in closed loop at idle at first, so you can tune in the idle A/F fairly good. If you send an msq file, be sure to let me know the specifics of your setup: fuel injector size, idle fuel pressure, running spark and fuel, and if you have low or high impeadance injectors.
