TPS Trick and V-AFC or S-AFC

[lundgren]

A Quick thought for those with a V-AFC, or even the Super AFC, and this TPS trick. The signal to to the AFC unit should be the 'real' signal, so you'll want to intercept the TPS signal AFTER the AFC. Now the AFC unit simply 'taps' into this line. It will have to 'tap in' before the sensor in this manner:


TPS Sensor ---- TAP ----- Relay Unit ---- ECU

Just a thought for those with a AFC unit installed.

Actually... I changed my opinion here on this issue.

If the TPS mod is wired up BEFORE the V-AFC tap, then the V-AFC can use it's FULL throttle position mode, to change how fuel changes occur, under boost.

Currently, the V-AFC will only work based on actual TPS, which you can move to be 'about' when you get into boost, but doing it like below, part throttle is off boost, full throttle is under boost. I think when I do it, I'll put it thus:

TPS Sensor ---- Relay Unit ---- V-AFC TAP ---- ECU.

I'll loost the interpolated values from part to full throttle, but only under boost.
