Hello all, I have very little experience with tuning. That being said, I have a mostly stock 88 mustang with some bolt ons. I just installed the new ecu, and have loaded a base tune. I believe I have all the initial setup things correct, the car starts and seems to run ok, but then it just falls on its face and dies. Not much I can do to keep it running.

I would be more than happy to pay someone to help walk me through getting this running correctly if anyone does remote tuning.

I have attached the .msq and the log file. The log file is basically me starting the car, and everytime it starts to die I try to give it fuel but it still ends up dying.

This tune is far from base.

I set all the basics, I haven't changed a whole lot. What are you referring to?

Don't know where you got the "Base Tune", but it is not this.

These are just 2, there are many more.

1. You're never going to tune it with a Narrow Band O2.
2. Over-run fuel cutoff is enabled to cut fuel over 2000 rpm.
