I have a supercharged TJ with Moritech fitted to it. I need to revert the car temporarily to Standard (N/A)
How do I go about reverting to the Standard computer. ?

if you load the original map, it will set all values to 0, so essentially not altering the ECU signals.
do you save a zero map?

EDIT: or you can save a copy of the non N/A tune, then you can just reset all values to 0. i think there is an option in one of the menus at the top of the screen. do it for all maps that have been altered. ie: fuel, ignition timing, boost control, ect
then when you need to put the charger back on, just load the boost map, that you saved, back on
