Wiring Up Attessa To Work With Aftermarket Ecu's

[CruiseLiner]

how can i get attessa workin with an aftermarket ecu, anyone happen to know???? autronics is what i got but i cant tap into the tps signal for atessa ecu without altering volts from the autronics affecting the tps reading (100% throttle shows 20% throttle with attessa wired up off tps sensor as well because of voltage drop)

surely someone must know ????

could i wire the stagea ecu up to ignition with just the attessa wires going to it and would it make 4wd work correctly without all the other engine sensor wires connected?

theres 3 wires from the attessa ecu that connect to the factory ecu and they are...

throttle signal +

throttle signal -

tacho signal

tacho is easy, its the 2 tps wires i cant work out without affecting the ecu tps readings.

hope someone has some info

I know squat - having a RWD an all, but wouldnt something need to be wired up to sense wheel speed verses car speed?

The following may help. It is from the R32 GTR so the Engine ECCS pinouts will be different, but the voltages and wiring should be the same.
