HHO Mileage

With a setting of 275mv as a base to the O2 sensors, driving only local, the Trac averaged 13.9 mpg which was 2.7% less than my mpg with the EFIE set at 350mv which was 14.3mpg yet better than my base mpg of 13mpg. If you recall at 350mv the Trac ran like crap.

Now I raised the base mv to the O2 sensors to 300mv driving only local, the Trac averaged 15.6 mpg which was 10.9% more than my mpg with the EFIE set at 275mv

My no HHO local mileage is 13mpg So with HHO I get 15.6 that's a 16.67% overall improvement. The truck still runs smooth with no loss in power or performance. I will increase the base mv to 310mv & see the results.

I will post in another 100 miles what my findings are.
