Since the O2 sensor is located in the EXHAUST, I don't think you want to inject the HHO AFTER the O2 Sensor. Big Bang.
I think what you meant, was after the MAP/MAF sensor in the air intake.
I have a 91 Chrysler and it loves HHO, but I did need to treat the O2 sensor with an EFIE. Fortunately, my car only had 1 sensor.
1991 Plymouth Acclaim 3L V6.
1 dry cells with nineteen 6"x8" 316L ss plates, driven by constant current PWM set at 35 amps (13.3V at PWM). 28% KOH electrolyte. Total measured output 2.5 lpm. Mileage went from 18 to 26 mpg, all city driving (44% increase). EFIE set at .370 and I still need to play with ignition timing.
