Non linear TPS signal, jumps around, tried everything.
So I wired up a VL turbo TPS to this car, the white na6 18PSI loves
And the signal jumped all over the shop.
So I sent it to gslender, and he tested the ecu and got a linear readout, and updated the firmware to a non broken version.
So I ordered a new universal TPS from Wolf ECU and its does the same god damned thing.
If you calibrate the tps, and then you open and close it the tps might go to 130% at WOT.
So you calibrate it and now it only goes to 85% at WOT.
And then you open it slowly and smoothly and it might hit 12% by half way down then jump to 40% soon after drop to zero for a bit and so on untuil it ends up at 126.3% or some ****.
So WTF, is there something basic Ive missed or do I need to run fresh wires from TPS to the MS or what?
its a brain MS2.
