I've been searching around for some answers but not been able to find anything specific enough, so asking for some help please!

I've just dropped a spec 1 RB25DET into my R32, using the RB20 loom and RB25 ECU. I've got it running on 4, had a listen to it and injectors 3 and 4 don't seem to be firing?

Anybody had this issue or have any ideas what it might be?

Any help appreciated!

Cheers
Si

I'm not certain but of the top of my head, I think injectors 3 and 4 need to be switched over with each other when using the rb25 ecu.
On my own conversion I used the rb20ecu so I didn't need to do this but I do remember reading this somewhere. Think it was on the SAU site possibly but can't remember for sure.

Do a bit more research and you should find this may be your problem.

According to the research I did it was injectors 4 and 6 (pins 112 and 114 on the ECU or something?) so I have done that, also tried it with the wires switched back the other way...

I hate wiring!

Did yours just run as normal on the 20DET ECU or did it need a map?
