High RPM - Datalog Stops - Tweecer

Anything about Ford EEC tuning. TwEECer and Moates questions dominate, but there's some SCT and OBD-II knowledge too.

High RPM - Datalog Stops - Tweecer

Post by Project Reef Blue » Sun Dec 23, 2018 12:04 pm

Hey Guys,
Looking for some guidance with my combination. I have noticed above ~5000datalog starts to slow down and by 5500rpm basically stops updating. It logs cells of the same data in large blocks - meanwhile the engine is continuing to rev up cleanly. The combination is a 93 Mustang with A9L computer running an N/A 408". Shift light set at 6400rpm. I have attached a datalog and the video taken from a test and tune session.

Is this normal?

With previous combination (NA 306") I did not experience this issue. RPM always climbed as expected and there was no stalling of the data all the way upto 6500rpm.
