Hello All,

I have had EFILive for 3 trucks now and never needed to do anything but load tunes. However, I cooked my ECM doing some maintenance and had to order a new ECM. I provided them with my VIN and received the ECM. Edit: It is a reman ecm if that matters.

Can I use my Autocal V3 to program a stock file? or, do I need the dealer to flash it first?

Any assistance is greatly appreciated!
