Would the PCM ever know if the engine was running on 3 cylinders at all? Because my idea for that is just cutting off the signal to the injectors, which again is an output from the PCM, which doesn't receive input confirming the signal was received by the injector(s) (to my understanding). Someone with more PCM knowledge can chime in at any time. I also am trying to learn more about these things, because as stated previously in this thread I was also planning on utilizing an open source PCM option, so anything and everything is possible when it comes to programming.
