Welcome to the one if by land, two if by sea 50-in-1 electronic playground edition of the Tool of the Week. This time around we’re peering into computerized technology. The 1987 Mitsubishi Starion is a fuel injected car, but by no means modern. The transitional period between carburated and electronically injected engines produced some interesting if not cantankerous systems. The two-injector throttle body injection on the Starion falls into the island of misfit toys category, but the car is equipped with fully transistorized Electronic Control Unit. Any ECU made after 1995 can be accessed with a readily available universal engine code reader to help sort out check engine lights. The only people that had a Mitsubishi code reader back in 1987 were Mitsubishi (and Chrysler) dealerships. These machines were a few steps ahead of ENIAC, and about as expensive. Proving that you can learn and save money on the internets is the forum post that provided the knowledge to solder together this simple engine code reader from a two-dollar 12V LED and thirty-cent alligator clips from the local Radio Shack. Just find the pin outs and count the blinks.
