Logger missing data

[Blindsey]

My car hiccups around 5000RPM, After going back and reviewing the log i don't have any data right when the hiccup occurs. I'm stumped what is going on?

Perhaps the ECU reset. Use one of your spares and see if the same thing happens.

I dont have a spare Eprom.

Then watch the CEL to see if it turns on at the same time as it hiccups. How much data is missing?

No CEL. At 5000RPM to 5800RPM then pulls extremely hard to redline. Everything looks normal, just the hiccup and missing data.
