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.

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
