Anyone know bout this? Whats your trouble shooting process?
I fear if it is then I will have to buy a MAP sensor enhancer and O2 EFIE. The MAP sensor enhancer I see as simple enough to hook up but the O2 EFIE I'm still a bit confused about. I have a 97 Accord so I'm guessing I will need both.
Anyone know how I can maximize my results for city driving? I have a dry cell with a bubbler that is connected to a hole in my cold air intake closest to the throttle body after the PCV valve.
The PCV vacuum is in the intake plenum on the downside of the throttle plate. If you have your HHO tubed in through the crankcase vent tube(not pcv) then you need to dedicate a feed line to the HHO by itself for intake feed. Or put a check valve on the valve cover side of what you have. You don't want to feed the crankcase your HHO just the intake !
By the way you have a distributor and if you take it out and elongate the holes(there not adjustable on most now) for mounting you can retard the timing by 3-4 degrees and that will help your burn with the HHO as well, meaning you will see improved results. BE SURE you mark where the two are before you adjust, use a chisel to mark between the distributor and the head before you pull it out so you can always return it to there. As well you can only put it back in one way as the shaft is offset.
Its done right or its not done !
Hail HHO.
