I may be sailing into uncharted waters here, but I?m hoping someone out there may know something that can help me. What I have is a 94 civic vx totally stock except for a larger exhaust. (after the stock cat of course) I have introduced 4 bottles of HHO producing about 500 milliliters (.5 liters) a minute at a cost of about 12 amps. I have the voltage divided by 4 so it is more efficient and am using steel plates at .4 mm spacing, KOH as a catalyst. Enough on that, here?s where I need help, I am seeing power increases, but I want mpg. I recently bought an apexi neo afc piggyback fuel controller for this application but in looking at their wiring manual, it makes exception to the vtec-e models for wiring harness pinouts. Has anyone actually tried to hook up one of these? If not, does anyone know where I can get a diagram of the ecu pinouts for a vx?
