I've just been installing the MFD as of last night - and have a bit of a question:
So far I've only installed the power/acc/ign, 3 gauge cluster wires (illumination/oil temperature/boost) & dash wires (water/oil pressure) - next up is the wires from the ECU (speed, injector duty, revs, throttle position) -- but on doing a test power-up to make sure everything is fine, only water temp seems to be showing up. I've tried running the diags to test sensors, and even then whilst it seems to detect sensors, nothing is really coming up besides water temp - boost just sits at 0. I've checked, double-checked, and triple checked the conncetions. Does anyone know if this is normal?
I'm wondering if maybe it's needing the inj/speed/throttle sensors from the ECU before it'll initialise the other sensors properly? I'm hoping that's the case anyway. Ah well, I guess I'll put in the remainder of the ECU wiring and see what happens. Otherwise, I'll be trying to track down whether it's a grounding problem or something else weird.
Fingers crossed this unit isnt a dud (it came from a working car) - I can't imagine how much it would cost to repair
