Help with anomaly

[94tang]

Been having an issue lately and dont know if its tune related or an electrical gremlin. Usually happens with steady light throttle input. The car hesitates for a split second as im cruising along. So far it hasn't happened at WOT. If my picture loads it will be marked with white arrows.

ok your issue may be a few things, the RPM signal into the ecu [from the pip] shows 15000 rpm for a split second this is your hiccup. I do not see the other sensors freaking out so we can rule out an issue at the ecu.

So what would cause the false rpm signal?...bad pip?...bad distributor?....bad tfi module?

well you are not currently data-logging the status bits so i cant see status #2 for sync loss. when this happens do you get an upcount on the sync loss gauge in TS?

Honestly dont know Steve. Ill turn that on and get another dl

Well i got another datalog, but the car didnt act up this time. It usually does at least once or twice while im driving. The above datalog doesnt show it, but i think it actually did it 3 times total.

I would suspect the pip sensor first.
