    • … will only compensate for the extra oxygen it will see in the exhaust from the O2 sensors and bring the A/F ratio back to 14.7:1. Then you will most certainly see your fuel mpg to drop. On this site there are plans and schematics for hydrogen cells and EFIE, MAF or MAP schematics with instructions …

    • … there was no mileage gain at all. The EFIE adds a little voltage to the O2 sensors voltage. The ECM (computer) thinks it is sending too much gasoline, so it leans out the mixture. Sends less gasoline. The cell is controlled from the dash. I use a Digital Amp Meter to monitor the cell current, and Digital …
