So I just received an M-box with aj-fonz tune.  Installed the ecm, was able to get everything communicating beautifully.

Flashed my prepared file.

Boom, it runs!  Shut it off, go to restart, nothing.

I attempted to reconnect to the ecm, unsuccessful.

The only way to reconnect or start the car is to reinstall my old ECM, start the car, then remove and reinstall the new ECM.  I can then flash, and start one time before we repeat.

Thoughts?

Also worth noting, before I did anything I was able to start the car multiple times with the tune thT was already on the m-box.

Yessir, after posting that I managed to dig up some answers.  I guess I had the old checker linked in the"getting started page", had some trouble getting to work.

Got the new program, and sure enough had 6 errors.  Repaired, flashed, and we're in business!

Thanks!
