Can you run the composite log until the loss of sync problem pops up (it was still synced fine at the end of that log), and also post your MSQ?

The composite log was not synced at the very beginning, but I couldn't tell what caused it to lose sync. Can you post a composite log that shows it going from correctly synced to the signal disappearing?

ok guys have a ? does the cam trigger needs to be on the exhaust or intake cam or that does not matter?

It wouldn't matter as long as it occurs in the correct spot relative to the crank wheel and tooth #1 angle.

I think I found 2 problem 1st one I put a pullup on the looms of my cherrys sensor and built my ms tach input for vr+pullup for hall at the same time and I think that I should take the pullup out of the tach inputs on my ms. and 2nd my cam indicator its right at tdc with my #1 tooth.

heres a better pic of what happen on the composite logger

[Matt Cramer]

That looks like what you should be seeing. No loss of sync or signal in that picture.

well I rearrange my cam sensor and the car start the only think its that sometimes when I try to start the car Im getting a check engine ,sync fault but the car start idle perfect.
