OBII Smarter than us?

OK I have tried a lot of things on a 2000 Mercury Grand Marquises. (HHO, water injection with and without Menthol, resetting Air/Fuel ratios, many interrupts to the sensors, gas additives, throttle body mod, )

This is an OBII car. And nothing seems to be able to get better than 34MPG.

So the question is: Are these programed to keep ANY improvement from working, IE is the computer stopping me.

Has anyone had any real progress with any of these cars? (And I don’t mean hypermileing…)

I want to be able to make better MPG in all OBDII Cars.

Rich
