Ran the tune this morning and strangely it ran a full 2pts richer across the board as oppposed to the exact same tune I was running the day before on COS3 02020003.
So....I guess there are deffinately some differences in the files we DON'T see.

Howard,

Compared to GM Software "INCA 7.1" there are many parameters not listed and you could be right. Most of the missing parameters are not required and will only add to the confusion.

I am interested in how you fair up with that lean throttle tip in issue now you have changed operating systems.

I think from memory this was a operating system part number Jeff uses.

You are quite the adventurer now, I am glad you are more comfortable with tuning your own vehicle.

Cheers
