tc-hybrid Posted November 15, 2008 Share Posted November 15, 2008 I have a 92 SC400 and have placed HHO technology on it to improve gas milage. It has raised me from 16 mpg to 23 mpg city driving, but I had to wiring around the o2 sensors to change the signal to lean the fuel mixture. However, when I have modified other cars (honda, fords, etc.) I have modified the MAP sensor and just pulled the o2 sensors out of the exhaust stream. My trouble is the Karmen-Vortex Mass air flow sensor on my 92 sends a band metered width signal my normal MAP Enhancers cannot replicate. Does anyone know how to set up a electronic adjustable enhancer to change the metered signal to the ECU to tell it to lean the fuel mixture?
