EcuMate readings

[Jonny_b]

Ecumate is reading 11.3 at the ECU, yet my voltmeter is reading 12.6v at the battery. Should I be alarmed? Where does the ECU earth? On the transmission tunnel bolts or somewhere else?

Thanks

Do a voltage check on the AFM plug- it uses the same 12v supply as the ECU.

Red/black. Ground
Brown Orange +12v

I dont know if this applies to the ECUmate, but the very early versions of RoverGauge used to under read the voltage via the OBD port for some reason, that was fixed in an update. I dont know if Steve ever did any software updates for the ECUmate- You need to check with him if this was ever an issue.
