ZeroHydro Fuel or Volo

Been away for a week to do some extensive testing with the following setup on my Mazda CX-9

- Double O2 extenders, HHO, FS2 = no gains to slight loss plus CELs relating to O2 flow rates

- HHO and FS2 = slight gain to unchange

- HHO only = same as above

- FS2 only = same as above

In all the above scenarios, I ran a full tank of gas on each setup. One thing I did notice which was a bit disturbing was that the FS2 was causing the engine to knock at low rpms with load. Once I removed the FS2, knock went away. Guess it's time for a Quad EFIE

I dont think you need the quad, Ide go with this one in the link, its $75. but if you feel better controlling all 4 go for it.

Leaning towards quad because my ECM is tuned for CARB. So there's a good chance that the downstream O2 sensors are part of the fuel delivery equation.

cool, better safe the sorry. good luck with it and keep us posted

Ben Ben01....
This might be a dumb question but... Did you reset the FS2 before each test?
I just did my first test with FS2& HHO (1-1.2 LPM) and I want from my usual 17MPG to 22.8MPG (156 miles)
I just pulled my camper back home today, I hav'nt filled up yet to see but I usually get 7-9 MPG. My engine did sound different this time. It sounded more "throaty" Like when a 4 barrel carb. kicks in I'll let you know. I think its working for me.???!

Have any of you guys with FS2s taken a codes reading on your vehicle?
I'm not sure weather its the chip or my van that non available codes for cooling and bunch of other stuff.

I think my van is still running in open loop. I have to by a affordable scanner if i can find one.

I have the ScanGauge set up in my truck that has the FS2
It reads codes and all kinds of stuff. It tells me if I'm in open loop or closed, AFR, torque, Hp, air temp,coolant temp, timing, load................................

I have not thrown codes let.
But I did use it to read codes on my sisters car!
