I realize that most modern cars have complex elaborate ignition computers that regulate the flow of air and gasoline into the engine using a vast array of sensors to prevent the need for tuneups, and improve ignition stability and gas mileage. I realize also that any conversion kit to CNG brings a new set of ignition parameters to the table, and that existing sensors, and computer settings will not work for optimal CNG ignition. Howerver that being said, it seems to me that a standardized electronic adapter could be created to "Fool" the vastly differing ignition computer systems in a "Standard" way, since the sensors used on most cars are nearly identical in electrical characteristics. (The computers are very different, but the output of the sensors is nearly identical) So to make an inexpensive "Universal" conversion kit, all you need to do is "Alter" the signal reports being sent back to the ignition computer from the sensors in a "Standard" way and you have a universally compatible conversion kit system. Then all cars could be converted with the same conversion kit. Has anyone approached the conversion kit problem from this angle? If this issue is taken care of then the rest of the conversion kit could be an EPA approved standard kit, and we wouldn't need to have every model year of every manufacturer go through the expensive EPA approval process. The pre-approved Universal kit could be used for any car and the mountains of Government "Red Tape" would be removed from the CNG conversion process.
