hey op your problem sounds almost like mine i jus finished a b18c type r swap into my ek1. running ek4 loom and standard type r ecu.
all is running well except i have now lost my tacho and possibly my temp gauge.
Has any one had this issue before and have any idea of what it could be. I've read of something to do with a little blue wire?
There's a blue wire that goes from the tachometer to the cabin harness plug on the drivers side. There is also a little brown grounding wire that goes from the same plug back to the Ecu
The problem was immobiliser.
Someone had ripped the PCB chip off the ecu board rather than bypassing correctly.
Has now been fixed and is waiting on a knock sensor before tracking it.
