s-afc2 throttle %
 

hey guys,
iv got an s-afc2 in my s4 turbo and i'm going to get it dyno tuned in a couple of weeks time. just before i put it on the dyno, i want to get the afc to display the proper amount of throttle so i can utilise the hi and low maps. i know its been talked about b4, i searched and cannot find how you re-wire it. i know u have to tap into the pressure sensor but there are a few wires and i'm not willing to use the guess and check method. thanks a lot for your help

Like the above thread says wiring the S-AFC's throttle sensor to the ECU pressure signal is the way to go, especially with an S4.
