Glad to offer something useful. Hopefully you'll have that offset problem fixed now with the new cutoff level on the SG? I know my Elantra showed some really high numbers when I got the SG-II (my other one is a SG-I and doesn't have a fuel cutoff adjustment at all) so I quickly adjusted it to zero and the numbers went back to normal. My first clue was seeing the instantaneous jump to 9999 at the top of a pulse as soon as I let off the pedal to start my coast. Good luck and keep us posted!
