I know there are tons of readers and software on the market, but what I really need is something to convert signals of my1970s sensors (fuel level, speed, coolant temp, etc) to OBD compliant signals. I realize certain components like a pulse generator might be required. I'm ok with that.
Any info converting standard, pre-OBD signals to OBD is welcome!
NOTE: The vehicle I'm working on is a Chevrolet Corvette, but the principles should be same for all pre-OBD vehicles.
