All on single cam wheel, with 12-1 trigger, reported RPMs in TS using bench test rig on lowest speed setting (RPMs are higher than the cordless drill which is about 800 crank speed)

All of the above I did on a MacBook, using Windows XP running in Parallels 9. Did a back to back in Mac OS 10.9.4 and open Tunerstudio, created new projects, but used same controllers (MicroSquirts) and the only odd thing now, is the speed is being reported OK in 2.891 now, so I'll have to go back and double check the Windows TS version. 3.83 is still showing the half speed error, but I cannot seem to get this too work without Autotrigger, despite having the right 12-1 & 6 skip teeth in the dialog boxes.

OK, so there is NO issue with 2.890 with a single cam wheel, I've double checked in XP using the test rig, and have no idea what happened.

The only issue is version 3.830 reports half speed in TunerStudio

Mike,

Good job, now everybody can see that error on your pictures.

Now I'm working on other things(ECU functional tests, wiring, injector flow test ... ) to get my bike done.
I loaded latest working version 3.76 and stay on that while that bug exist in 3.83 code.
I hope that software developers will fix it.
I checked firmware change log and noticed that error appeared when sequencer stuff was included.
