Re: sync problem
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?

Re: sync problem
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?elturbonitroso wrote:sorry for the delay was out on the weekend heres another composite log and a thooth log

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

Re: sync problem
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.

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