i just found this site and i'm starting to go through it to see what the consensus is. i have a 97 saturn 1.9 auto. i got a system from greensource-ca and the vessel leaded like a sieve. it put more gas in the air than in the engine. i took it apart and removed the cover over the plates to let the fluid circulate better that helped. then i sealed it up so it doesn't leak into the air. the efie is hard to adjust and all the instructions were backwards, for my installation. they have no readout on the efie so i had to bring wires out and connect a voltmeter to it so can see the readings while i'm setting it up. i can't make the engine do anything when i trim the pot. i see the voltage move but the engine does nothing yet, except make my mileage continues to go down. the car without the hho get 27 mpg steady and now it is down to 25 mpg.
i tried a different pwm and efie from ebay and the pwm worked great but the efie made the engine stall. and when i measured the output voltage i got 12.5 going to the ecu. so that unit was junk. i tired both channels on that unit.
now maybe i can get real help on this site. my generator is putting out 5-8 amps and i understand that this may be the correct amount for a 1.9 engine maybe even a bit to much but with the other devices not working good and poor instructions i have no place to go. thanks maybe some one here can help. thanks bob p.
