tps signal is wrong
« on: April 09, 2008, 05:52:32 pm »
Hi All.


On my old Subaru Legacy Turbo, the TPS signal is going from high voltage, when throttle is closed, to low voltage when going wot.

And this is also wrong in megatune,

So the q is,

Do i have to change the wiring, or can i change something in megatune to invert it?


Thanks,

Just set your low and high tdc values accordingly - the software can differentiate between the two :)

I use a Subaru TPS on my TVR now.  It's a variable resistor, so can be wired backwards if you really want to.
