    Just as the title says. One of our members, Chris Spies of mtpturbo has a very well written and informative article in the latest FastestStreetCar magazine. Chris is a M.E. and has penned several articles for the publication. This one is on the Accel Gen VII ecu and gives a great overview. Just wanted to give some props.

    Good job Chris!

    Thanks, Mark.

    The DFI piece was a last minute deal so it is a bit rough around the edges, but I think it gives a nice overview of the system in its current form.

    If I get a few minutes I'll scan it and post a link.

    VERY nice article Chris! The Gen 7 is definitely one of the older systems available now, but it is a very well thought-out system that still gives even the latest toys on the market a run for their money. In my opinion, the time this system has been on the market should serve as a testament to its marketability; it would have died a long time ago if it was anything other than first-rate.

    This is only a guess but I would say to look for a short from the wiring harness to ground. Error 51 is the 5v reference out of range which could be caused by a short from a 5v reference wire. When this happens the ecu sets a default value for all affected sensors. I would start another thread on the specific problem.
