hooking up SAFC to run MAP instead of TPS
 

what are the procedures to run MAP instead of TPS? its gonna be for a s4 that is gonna boost.
its on a s4 NA harness to s4 t2 ecu if it matters.

You need to use the gray wire coming out of the SAFC (the same one that is hooked up for TPS signal). It hooks up to the boost sensor output BEFORE THE FCD. For s4 it is a BROWN WIRE WITH A RED STRIPE, FOR s5 it would be GREEN WIRE WITH YELLOW STRIPE.

Change sensor type to pressure from TPS.

I have the same question except I'm using all s4 na (ECU, harness, etc.). I'm thinking about using a GM 3-BAR map sensor as the boost signal input. Is it just as simple as wireing the sensor to the grey wire?

where can I find more infomation on this

could allways order a jumper harness. nobody likes spliced harnesses :wallbash:
