My hope to find something that would limit the reading beyond a certain resistance value would prevent the computer from throwing up red flags.
I did this from my head to the completed project so i dont have a diagram.
Basically, this is placed between the sensor and the computer, through a 6 position rotary switch which then goes to the circuit board and the various resistors.
The sensor should operate through the unit but depending on the setting, the additional resistance is added.
My guess is the computer will throw up the red flags when a resistance of 4-5K is achieved.
My added resistance values start at 47 and go to 3,400.
If the sensors actual functioning value at a full engine load is say........3,600 then the value of the setting is added, the computer will not be happy.
The sensor operates from 0 (or almost zero) going up in value depending on engine load.
Is my explanation helping or just confusing you and making me look worse? :-/
