Well it has been a long road ... and a lot of tweaking. Our final set up... Single Cell with bubbler, Single EFIE Offset 280-285, Sub O2 sensor wrapped in tin foil, 52.7 mpg
Before wrapping the sub sensor we were getting only 38 mpg... however it would not hold, it was driving us crazy.
Then we were having heating problems with the electrolizer, so we cut down on catalyst and added a bubbler.
We have a California Engine, and just found out that the Ox sub-sensor works the same as the main Ox sensor... so we wrapped it back up... and that was the ticket... will do more tests... to see what happens...
It's all good.
