So, I am running slower than normal 15 counters would. Normal logging can't touch that kind of rate.
Sweet. I'm so glad I found out about this haha. I have mine set up to start logging during throttle opening angle above 60% and if there is any knock above 2000 rpm. It stops logging when rpms drop below 2k. Such a neat tool!
