Here's a question for anyone who has a Scangauge 2 in their car.
I have so far driven this installation 58 miles on HHO. The AVG MPG reading on my scangauge2 has been reading lower than it was w/o HHO.
The regular MPG reading shows a slight inprovement. Has anyone with a scangauge experience skewed reading with HHO, or should I be suspecting the MPG have worsened?
If in fact it has worsened (which I will calculate at fill up), my next move should be to continue tweaking the EFIE. (I'm at 315mv right now)? This is my 1st foray into an OBD2/ECU controlled vehicle. Old carbed cars are so much easier.

One benefit I have seen to adding the HHO to the Trac has been on start up. Sport Tracs are notorious for requiring the key to be turned to the on position 2 or 3 times before they will start on the first shot. (fuel pump pressure) With HHO my Trac ALWAYS starts on shot 1. Just an observation.
