[Phantom]

I have been using it for my last two tanks and have had no problems the total miles were off a little about 0.1 extra miles every 45mi but I adjusted that and now it is 0.1mi under for every 120mi. I did not get to check the actual gal used to gal displayed since last time I did not select tank filled so I could not correct that.

It seems like the Ultra-gauge is accurate and works well. I just started using the "J1962 Y cable" this week and it did not change the function at all but I have not hooked up my scanner/programmer to it at the same time yet.
