Put in wrong forum, Predator used with same car, but 2 ec's

[Brian2797]

I took out my stage 1 ecu with a cmr tune it, I replaced it with my stock pc to get it to pass emissions. I had a cmr tune put into the stock ec to disable the misfire code to get the car to pass emissions. I took the stock ec back in the car without installing the original backup. I've tried everything. I can't get the predator to let me reinstall the original backup on either ec's. I have both original backup files on my laptop. What do I need to do? Do I need to put the stock ec in the car and have I re-flashed, then pull the original off of it, and then reset the tool? Any ideas??? Thanks
