I am totally new to the writing-in-a-forum-thing. (Long time viewer, first time writer). But everybody here seems so nice and friendly, it has been a pleasure to observe and learn. Here is my question: There seem to be a number of companies making aftermarket ECU's. IPD, Upsolute, Eastern Aerospace etc. I would love to hear the feedback from people's experiences. Is there one to steer clear of? Is there one ABSOLUTE MUST! (Hopefully, this will spark some neat discussion.)
