Multi Tunes and the requirements


Recommended Posts

What are the must do requirements before looking at doing the Multi-Tunes setup. ive heard that you need a bf loom and a bf mk2 onwards ecu for this to actually work or will a factory BA xr6 turbo ecu and loom work. note its still in a 2003 falcon.

All BA through FGX support the multi tune providing the cruise control buttons are wired up and functional. So technically any loom is fine providing that part is sorted. Cruise control is wired to pin 33 and 16 on the centre B plug, polarity doesn't matter as its just a resistor network. I've wired one up on the bench like this.

The only cars that don't support the multi tune are the 4.0 FG Mk1 with the 5R55 5 speed auto. These must be converted to a manual or a 6 speed ZF auto.
