kind of a weird deal.supergas car-msd7al-3 on car.35 degrees total timing with flying crank trigger. all msd parts.at idle car has 35 degrees total timing,as soon as you rev it up it drops 10 degrees timing! tried 3 dif timing lights-2 different boxes-changed all the chips-changed crank trigger sensor.msd says it can't do that . took dist out and checked gear and camshaft-all perfect.it idles at 1200 rpm,as soon as it gets to 1500 rpm it drops 10 degrees instantly,we raced the car by setting the timing at 45 degrees and as soon as it goes up it drops to 35 degrees.went 3 rounds that way.but it ain't right! also run a shielded crank sensor wire. have been told to look at all the grounds on car.this car is 2 years old and nothing has been moved or changed. thought maybe somebody out there has seen this before.low profile billet dist for crank sensor setup.
