Subject: 7730 to 7749


For openers is you application MAF, or MAP?.  If MAF then
I don't know if the 749 would support it.  I had tried using a 808
cal inna 730 but turned out it wouldn't run unless loaded 2x into
the memcal.  Are you wanting to run the 730 cal in the 749?.
Are you going to use the 749 initially with a 2 bar MAP?.
  Rather than jumping to the 749, I'd say get a diacom, or some
such tool where you can record all you injector pulse widths,
and do that first.  Maybe buy, and wire in a 2 bar MAP, and
record it's readings to whatever your running now.  Once you
get a really complete fuel/spark table then get a 749 promgrammer
and the misc stuff to do proms, and figure out a 749 prom for
what you have already.
  Even things like type of VSS need considered
Cheers

same pinout?)
>Does anyone know anything about the DIS/Dizzy thing?

might work.  Is this totally rediculous idea?
