Default Need Help ASAP


My downpipe is in and ready to flash stage II. I am already stage I. Do I go throught the process I went through to get to Stage 1?

Key off
green connectors then turn on AP?

I'm basically doing map changing and the directions state I need to be in ECU programming mode which I'm guessing is the green connectors and the key in the "on" position?

If you want to flash a new basemap on then yes, you have to go through the reflash process like you did to install the AccessPORT initially. However, you can flash a map on as realtime and it will work just as well. However, if you reset your ECU or lose power etc, the map will revert back to whatever the basemap is.
