Hey guys.
I hooked up the MPGuino in my 94 Civic DX today and I noticed something about it which is problematic.
I incorporated a power switch in the circuit so that the MPGuino doesn't have to be on when the car is off and parked.
However, when I turn the power off I lose my Tank miles and distance.
My U/Sec and VSS Pulse figures remain saved though.

Any way to fix this?
Or does everyone else leave their MPGuinos powered on all the time?

Thanks.

JJ
