Did anyone ever try to solder a switch to the jumer points instead of the permenet jumper?
The idead is to easly switch between the stock and the Nistune ROMs.
I'm curious if the maps can be switched in whlie the car is running, but there is no way I'm risking my ECU just to satisfy my cusiousity.
You could throw the ECU into limp mode if you do it whilst running in worst case. The switch bounce will cause some jumping between internal/external rom until it settles
