Yeah I can't key off or it happens... So I guess I'll have to make a kill switch.

So do you think that is my problem Meelis? Just keying off messed it up for a bit?
If that's the case thn it doesn't make sense to me how it didn't get fixed after skis connecting it from the power and resetting everything...

If you key off the reed switch in our older cars no longer produces a signal. The ECU shuts down... maybe the combination of the 2 things cause the MPGuino to go nuts. I found if I shut down the engine with the key and wait 1 or 2 seconds before keying on again the MPGuino behaves.

When mine messed up it was some time before the MPGuino started working correctly again.... but it did start to work on it's own again.
