HHO STUFF
ive tried this stuff before on my 98 lumina 3.8L ... the problem is you have to take the sensor readings OUTSIDE of the normal ranges to notice any real mpg gain, thus it auctually shows more of a gain on a carburated cars than an ecu controlled car. BECAUSE with machanincal cars you just adjust the timing and the fuel mixture screw... BUT modern cars dont use a distrubitor or a fuel mixture screw, so it (the ecu) gets its readings from sensors ( maf, map, throttle positon, intake air, coolant temp, ect....) to control the mount of fuel used. so what u do is trick the ecu to thinking it dosent need much fuel, then you add the hho gas in it's place, thats how u get the mpg gains less gas more hho to maintain the same amount of power ( or vehicle speed) but when u start playing with the sensor readings and if you adjust it to far sometimes the ecu reverts back to programed tables from the factory -- basically the computer thinks the sensor is faulty and it runs its original program (stock). thus deleting any mpg gains you have made.... im NOT saying its BULL SHIT ---- but it's harder than they make it sound! TRUST ME I'VE DONE IT!!! now i've heard that with efi live ( for diesels) you have more control over the sensors... but im not sure i dont have efi live..... yet :D
