My car was tuned with LS1 Edit before I purchased it. I wanted to check before I purchased an HP Tuner. Will I be able to save the current file with HPTUNER? It seems very logical, but you never know until you know. I just want to change when my fans come on. I don't know why this wasn't done with all the mods the car has. However I was driven in Houston so maybe the weather didn't warrant that. Not sure...or maybe that was overlooked.
