My uncle's 94 5.0 EECIV bit the dust so we plugged in MS2 and it fired up and ran smooth for 30 seconds. He didn't want to run it much without putting in the proper settings so we shut it off. A few weeks ago why and he hooked up a mtx-l and called me to hookup a laptop to check and correct settings. Without doing another test start I make changes on the file and burn. Tried starting up and notice it's spitting out raw fuel like a dead miss, which it never had before. Shut it off and calibrated more things like thermistor, throttle, and checked that the mtx-l matched the tune studio gauges. Everything looked close but still pissing fuel. I couldn't figure out how to undo all the changes that I had made that day so I reloaded ms firmware and now everything is unconfigured and the car doesn't start. Does someone have a file I can load to just give me back to home base.
