Hey Andy! If MEGASQUIRT figures this out, it would be way cool. I, myself, still like the Delphi for street bikes. MAP and ION make the day for me. But for a race type application? This could be really cool.
IIRC, there are actaully three things that have to line up to get spark and fuel from a Delphi. The correct tooth on the crank, as read from the crank position sensor; A high map signal; which signifies the intake valve opened; and crank slow down for compression stroke. I also remember that the MAP signal is a 'check' value simply to insure the crank slow down is in a proper place. Roger, remember that there is 720* of crank rotation for a complete 4 cycle combustion process. Cars come this way too. Use a crank trigger (which happens TWICE for each combustion process and something else like a hi MAP signal to tell when a valve opens. Once this is found, the rest of the time the key is on, it remembers and does NOT do this for each revolution.
I looked at the MOTEC stuff for awhile, but have been awaiting the MS stuff to look at. WHile you have been gone, I bought a 250i dyno to play with and gather data like we used to talk about. Nice seeing you, dude!!!!!
Like I said, on the street, I will still take my Delphi. But for going fats and having controlled conditions, I think the Alpha N stuff can do a wonderful job, more than wonderful, actually. THIS is the stuff I wish Bob would talk about from his old days.....
Andy, I really hope you hang around, and this time NOT get frustrated, OK? Even with me sometimes.
