A31 / C33 Rb20det With R32 Ecu?

[CEE33T]

Hey there,

Just a quick question,

I was wondering if anyone knows if the C33 / A31 Rb20det ECU pinouts/wiring looms

are the same as the R32 Rb20det ECU pinouts, and if they are easy to change over.

the reason i ask is i own a '89 C33 RB20det and was thinking of trying to put the R33 Power FC into the car with the slight change to the ignition wiring.....

as seen HERE.

any help would be great.

thanks

Sean.

The R32 uses different sensors to the A31. ie all the looms have different plugs and are a "newer" generation to the poor old slummin 31. Not sure about pin outs and "readable voltages" etc

well from my experience, i have a spare '92 or '93 model r32gtst cpu when plugged up with my cefiro loom and running gear it started up and ran, although ran very poor like the firing order was out of sync and would run like bog. So yeah something is different...sensors i know have different plugs...AFM (green vs purple label), ignitor module different firing order..hmm not sure what else...

If you do find any pinout differences or anything else different about the looms etc please let me know.. as i want to swap my cefiro cpu for r32 one (its a long story so don't ask) when i have the time.

why would it be different? ive been running an RB20 PFC and has no problems, and just plugged in a 32 stock computer and is still running fine (minus all the fuel she spits back out due to still having the Z32 AFM hooked up

prob cos with PFC maps can be altered for different AFM voltage readings.
