Purchasing a new TCM and ECM both are available with nothing loaded (blank) Trying to avoid warranty issues later if needed. Can I just plug them both in and load the trans tune that was copied from the original and the engine tune was purchased as a stock replacement tune. Or what would be the best way to go about doing it. Never loaded an empty controller before. I have current V2 with 2 licenses left on it.

Also my Fuel system, Engine Diag and Engine operation numbers are all off by 1 number lower. Assuming these are a back dated software number not the latest version. Would this pose an issue ?

Thanks, Jeff
