OK, suppose I've decided to build a wicked NA 302 and tune it with the Tweecer R/T. I've discovered a wealth of random information on the net concerning EEC and the Tweecer. Ready to commit some serious study time so I can learn to finally become a good tuner. I have a very basic knowledge of how the PCM controls things. I believe I know where most all the sensors are. How to test many of them with a DVOM and such. In short, I possess a rudimentary big picture knowledge base of what an ECM/PCM does. Any suggestions on how I should take the next step? I know there is a book by Probst. Do I read that first, or does that do more harm than good since I understand the Fox computer is significantly different than the 94-95? Or do I wander around this, and other forums reading random threads? Haven't been to the Yahoo forum yet. Perhaps that is the genesis of all things tweecer? I'm very unsure of where the path to Tweecer wisdom begins.
