Looking for testemonial on converted Geo Tracker

[Jeffre W Lindow]

I am about to install a flex fuel kit on my 95 Geo Tracker. I recently built a hydrogen generater that boosted gas mileage 20% . Anyone with some history of how well the flex kit works on this vehicle???

I have a '90 Tracker, made hydrogen under the hood and got ~ 42MPG until the computer took over and leveled me down to about 24/25 MPG. Initial MPG was about 30 MPG (1.6L engine). I may have used about 2.5 oz acetone to 10 gals of the bad stuff. Installed potentiometers for city/hwy driving at the ox sensor. No other mods.
