Hey, I'm intending to put a z32 maf in, and see in the 1986-1988 HR31 (my car is 200zr z31) RB20DET installation instructions that the picture shows a resistor? near where the diode goes.
My ecu - does not - have this. The Op-Amp is there though
Question is - do I worrie? or continue?[/quote]

need to probably send a photo of your ECU.

I've changed the instructions tonight... please re-read and see the tech bulletin here

You will need to remove the 9th pin which is the omamp voltage. Zener is recommended still but now on pins 6 and 8 on reverse side of ECU
