Sync Loss Errors at 3500
Does this look like a crank sensor alignment issue or something else? I only get the issue at ~3500 rpm. The 99 crank sensor is a credit-card thickness from the tooth, maybe I need to pick up new feelers since the old ones were lost int he move. I'm guessing the swap between going high and low tells the story.
Thanks for the help.

Not to threadjack, but I've been having intermittent sync loss on my 2000 miata when the car is cold (below ~70c water temp). Does the car being cool indicate a specific issue?
It seems like it usually happens under light acceleration and I typically get somewhere between none and 5 counts until the car warms up. I keep messing with the crank sensor gap without any luck.

Yes. I remember previously that fouled plugs would whack-out the tach on a 1.6, but I believe I now have the tach driven from the CKP. Regardless, I'm changing plugs today, measuring gap on the CKP tomorrow and putting it at .030". I don't know what causes the logger to swap from high to low like that.

Yes pots. What kind of megasquirt is it? If it's an mslabs unit then nvm.
I've got a spare sensor or 2 I could loan you. Would just want it replaced if it fixes it.

Yep, ~2012 MSLabs MS3. Thanks for the offer but I think there is a spare sensor somewhere, in some box, from the move. I'm sure it's something super simple I overlooked. I can't remember most of what I need to from so long ago now that I'm a spandex clad bike saddle sniffer.

Maybe @Matt Cramer or @Ben might have some insight on why the logger flipped like that.
