Logging RPM

[oztracktuning]

I am having trouble logging RPM with the blackbox - it all works fine via the laptop. But the BB files have either very low rpm counts or in the last one zero.

Hoping someone can help. What am i doing wrong.

The problem is currently under investigation.
Are you using dynamic scan mode with more than 24 channels? If so, try reducing the channel count to 24 or less and using 10fps-Fast (also known as Stream-fast).

I tried programming less pids (12 channels only) and done in fast and in dynamic.

The last one had these pids installed in the black box.

I dont need them all installed do i. Which ones can i get rid of (from the black box logging pids)??

I know plx channel 2 is one of them.


It seemed that RPM didnt work and neither did ACCDEC Wheel Acceleration/Deceleration

Just validated pids again and all is well with 11 channels on fast 10fps logging.
