Was wondering do you need to have ecu loaded with race maps before you add a aftermarket controller like the jd. I have the powerup kit already done, but not the maps. Thanks
Far as I know there are no Race or any other maps for the 630 besides the 2 stock ones built into the ECU. The First stock map is the Low Power map which runs without the PU kit installed. The Second stock map is the High Power map which runs with the PU kit installed. The JD Tuner will run on top of whichever of the 2 stock maps is running.
