Battery Volts Reading on Nanocom Fluctuates

[Milton477]

Been trying out my new Nanocom & have notices a couple of things:


The Battery Voltage displayed on the Nanocom in Instrument Mode fluctuates up & down by 1v to 1.5v while my Pirana battery voltage meter is steady.
My Air Flow reads 0 at all times.
Waste Gate Modulator reads 0 at all times.

Thats what I have found so far. Now to tell the Minister of Finance about the expenditure as a result of the Nanocom.

My Air Flow reads 0 at all times. It should read at Idle 0 to 50 and 500/550 at 3000rpm
Waste Gate Modulator reads 0 at all times. Look under TP should read 0 to 15 depending on revs
Thats what I have found so far. Now to tell the Minister of Finance about the expenditure as a result of the Nanocom.

Further developments: When I access the BCU, something clicks in the instrument binacle or there abouts & all the gauges die along with the windows, indicators & central locking. Unplug the Nanocom, & a few seconds later, all is restored. Also, at the same time I had the starter motor start the engine with the ignition in position II. All this did happen after a drive through heavy rain though. Had to pull R2 in the fuse box to prevent the starter motor running on. Can't find any water ingress but I can repeat the fault (except starter) in my driveway. I just don't know anymore:confused::confused::confused::confused::co nfused::confused::confused::confused::confused::co nfused::confused::confused::confused::confused::co nfused::confused::confused::confused::confused::co nfused::confused:

I'd check for oil in the harness to the ECU and the plug at the front drivers side of the head where it comes out, the plug can fail or come off.
