O2 sensor offset for fuel economy ? Anyone experiment with, or have success with tweaking O2 sensor switch voltage for LEANER AFR in closed loop?
I tried a -30mV and it went richer. .. Next attempt is PLUS 30 mV
Going to shoot for 14.9 to 15 AFR in closed loop.
Power Enrich reacts pretty quick, cuts in at 115 kPa
Any chance I'll get another MILE per GALLON this way ?
My fuel tank is only 26 gallons, so one more MPG will get me 26 miles further down the road- for free-
Am I doing this right ?

For reference, GEN3 4.8 Liter, baby torque cam, TVS1900 blower at 11 PSI
