OK Got it locked down now.

OUCH Spoke too soon...

Switch to the Tank Big MPG readout and was driving and she locked up again.

I will now add a blocking diado and filter cap to the incoming 12 Volts.

The meter seems very senstive to voltage bumps.

Two things: a manual would be a big help, seems the trip miles reset with each turn on.

Which is what I am trying to do here, cover details as I learn them and pass them along.

The Tank miles are suppost to stay.

I had mine hooked up to a constant on 12 B+ on a relay I added to power up some add on gauges.

I am guessing there was some little backwards EMF coming off that relay.

Perhaps a little filtering to make them less sentive??

So I hard wired it driecly from the battery, same for the ground, it has not messed up for a couple of weeks.

So looks good.

So anyone done any thing with a TBI Motor like a Chevy 350 TBI??
