well b4 i post all my theory, research and design and construction and operation instructions lets start simple with the simple operation intent and parts list. Well to begin with the simple theory behind my design. I have installed a standalone water temp gauge and had to replace the factory temp sens with the new one. Problem being that is one of the cars main way of metering how much fuel is needed to ensure proper air fuel mixtures for cleanliness performance and fuel economy. therefore i now have to some how send the proper signal in voltage back to the computer. Second prob now being is with that circuit out not receiving any voltage what so ever the car now relays on the closed choke circuit to run the car on pre programmed air/fuel mixtures only with out help with any other sensor imput. Since i have over sized injectors its just way to much fuel and the car will almost not run.
well with some hard number crunching charting and lots of tech talk with my electronic expert my dad
lol i have now solved a way to now to only solve the preev problems i also stumbled upon a way to fool the car and make the computer it self hold open the injectors juss a bit longer or shorter "on" times by manually inputting false engine temperatures. well this is done by manually changing the voltage in variations from .8vdc to 4.91vdc over a instrument called a rheostat (controls voltage output by adding or decreasing the Resistance in the coiled wire contacting the wiper arm), after much fooling around i found the targetzone (area of air fuel mixture tables programmed into the computer where the factory emissions and horse power outputs are ac heaved). i have also found by turning down the dial (increasing the Resistance and decreasing the voltage output) it rich ens up the air fuel mixture and ultimately lets me use the full potential of my oversized injectors...its almost like reprogramming the computer to understand how to use the bigger injectors properly with over richning the mixture...to lean is worse way worse be carfull!!!
So after fooling around i found when the engine is above 140'F and i change the voltage output to more volts itle bring me down from the 140'F-1.35vdc air fuel mixture table and fool the car into putting slightly more choke on the motor and burn more gas, down to the 122'F-1.72vdc or the next more richer line the 104'F-2.16vdc i gain more power if the motor is actually 140'F, if not take your base engine temp reading and apply it to the proper line of the air fuel mixture...sub in the manual input in the corresponding voltage and re compensate...note i don't recommended turning the mixture tables leaner for less fuel consumption that leans the motor out and could be a real bad day for you...stay with in the targetzone or youl end up tripping the computer back to the closed circuit and the car will no longer run on your manually imputed air fuel tables itle be back on the pre programmed ones only...REMEMBER THIS IS ONLY ONE MANS EXPERIMENT AND IF YOU CHOOSE TO TRY IT YOUR AT YOUR OWN RISK JUST CUZ IT WORKED FOR ME DOESN'T MEAN YOU CANT SCREW SOMETHING BIG UP AND EITHER FRY YOUR ENGINE OR COMPUTER THKS... and i hope this adds power to all the under powered n/a 2.3ls out there
