I知 going to finish up the wiring on my Zeitronix wide band but I知 not sure where to tap in to get the RPM signal? Can someone point me in the right direction?

Pin 1X. It's on the large ECU plug to the far right. Bottom row, far left.

damn that has got to be the smallest picture ever. HAILERS eye sight ftw!!!!111!!!11!!

 

is that the stock ecu plug? I'm running the Microtech LT8.

 

just throwing it out there, but what about the trailing coil?

 

Well? Does not the large ECU plug still exist???? It should. It was not a part of the EM harness. It's an input signal to the ECU so it should be usable.

And yes, you could use the single bullet connector near the Trail coil assy. A yellow wire with a blue stripe (mabe just the opposite on colors). It's the tach signal just the same as pin 1X on the ECU. Seems the ECU plug (part of the F harness) would be closer.

 

This thread shows the stock ECU pinout. The large plug should still be there. Look at the NZCONVERTIBLE reply and HIS picture. It will enlage if you click on it.

 

i just found this:

cool, can I use the TPS pin for my wideband?

forget that I have an S5 engine in an S4 car, but the tach should still work.

 

I don't know about the tps part. It would seem not if your not using the stock ECU. The tps runs off a output from the ECU and you don't have the stock ECU. So I guess ....no.

Seems the Microtech would use the tps? Got me. No idea. Might ask on that aftermarket ecu forum OR/???????
