I know i'm bloody stuck with it now I guess
The problem I have with my stage 1 ecu by bell engineering its playing up at higher speed just doesn't respond
I'm not that tech minded but someone said about speed density set up. So I've got some self teaching ahead of me

The ECU can not be tuned so although the diagnostic plug wiring needs repairing it will be of no use on the dyno for tuning. The ecu is a stage one for set modifications so you you need to check you have the correct mods and everything is working as it should. Other than that there is no adjustment and you have moved away from the oem turbo/intake etc you will need a new ecu.

Its a stock R33 GTST ECU. I do not do them any more and I do not think anyone else in the UK ever managed to do them!

Ok. Thanks,as its one of your ecu,s can you read it and tell what size injectors etc are needed because everything in the engine bay looks oem.
I've gone back to a standard ecu now and it's driving really well,,but minus some hp
Sorry don't worry with a reply,just noticed my other posts from you
