Is there any other signal that could be used as an equivalent to the TPS signal. The issue I'm having is that the SupraStick for some odd reason is screwing with my TPS signal and messing up my ignition timing. I need another signal that has linear voltage rise in respect to throttle position. The MAF signal will not work in this situation because voltage changes with gear change.

Another option would be to somehow rig up a second TPS to the TB dedicate that to the SS but that seems like a lot of work.

Any ideas? Any way to prevent the SS from changing the voltage resolution or a device that I could purchase to put inline between the TPS signal and the SS?

 

No, there is only one TPS type signal, and that is the TPS. Have you tried using a diode where you tap into the TPS signal lead?

 

I have not tried using a diode but I will defenitely try it.
Without the SS, voltage range is 0.44-4.38 and when the SS is connected its 0.41-4.13
The SS is causing a voltage drop so I'm not sure if the diode would work but I will try it anyway. Any idea what kind of diode I need. I have a few Zener diodes, I dont remember the specs but they might be 1w 5.1V. Will they work or should I be looking for something else?

 

Also, since it seems that the SS is responsible for the voltage drop, would a resistor between the SS and TPS wire help? Theoritically with a resistor there, the path of least resistance would be the ECM and the EU which should both get a strong signal.
