Afternoon,

Got my Nanocom today, so have been eager to fiddle.
So far I've disabled the immobiliser to save myself from key issues, and also enabled dipped headlights on all the time.

One thing I noticed, was a setting for syncing the odometer.
Since I've had my P38, it always beeps with 'Odometer Error' on startup, and shows a mileage around ~85k
I clicked 'sync odometer' and my mileage jumped up to 104k. The error also went away.

I'm guessing that 104k is the actual milage, and someone before me fitted clocks with less miles? Or am I talking nonsense?

Also want to hear your other essential Nanocom changes/tips you've all done :)

Thanks

Check past MoT test history and see.

If either the odometer or BECM doesn't match then it will jump to the higher figure. Cluster or BECM might have been changed.

Good idea.

Just checked the MOT history, and it seems to align with the original figure of 85k.

Is what I've done reversible?

Not easily. Might be possible with Faultmate MSV?

Need someone more knowledgeable about where and how the data is stored. If you can work out how to change one of them then change it to 999,999 and reinstall and sync. Drive a mile or two to take it round the clock. Change it to the right number (which will now be higher) and sync again.

Thinking aloud, I wonder if you keep changing between miles and kilometres if it changes the number up each time?!

Not with a nano.
Only with faultmate and the BECM expensive pack.
But it could have been sorted apparently if you hadn’t done what you done.

@martyuk could do it I think. It's a BECM and binnacle out job to fix though. Unless you're really keen, I'd just try and live with it.

I have my wipers set to "speed". They go intermittent wiping whilst stopped at the lights.
