My batteries both went dead and I was wondering since you lose all your presets on your radio do you have to put the Predator program back in, or will it stay in even if your batts went dead??

I would say the tune would stay in..Cause when your battery goes dead it doesnt loose the data in your ECU/computer...Just my 2 cents

One you get the batteries charged, you can use the Predator to tell you which tune is installed - I think it is under the Options menu. My bet is you won't have to put the Predator program back in.

The program shouldn't be erased because it's stored as part of the ECM's permanent memory.
