Originally tuned by a friend back in 07, the car ran great for a few years. However, after getting a couple different parts for the 7, I decided it was time to update the tune. Prior to this I had little experience with megasquirt, as my friend had done most of the work with it. I went to open a new project in tunerstudio, and the car (running at the time), went from a nice idle to extremely rough and then stalling. Now the car wont start, or if it does it runs quite horribly. Looking at the msq, everything seems fine, and doing the normal adjustments to the tune seems to do virtually nothing. Any suggestions? I had my friend who originally tuned it look over the msq and adjust anything he saw out of place, but it still acts the same.

 

What MS version? Firmware version?
