I found a 911 turbo on my way home, logged a bit of our excursion. Please take a look and let me know if anything alarming(other than the MPH, which didn't update towards end of run). I assure you this was entirely off road, on a closed racing course.

The ZT-2 RPM is reading wayyyy low. I added OBD-II RPM, but doesn't update very often. Not sure if i need to calc it... I used the Yellow CPS feed per this:

I think you're supposed to set up the engine size as a 1 cylinder to have the correct RPM reading. Your RPM reading should have nothing to do with the OBD if you are using the ZT2. Did you buy the ZT2 add on for your Dashdaq?

 

Thanks Grip Grip, yes I'm running the zt-2 add on, purchased together and preloaded with the dashdaq unit.

I intuitively changed the cylinders from 4 to 6, I'll set it to 1, thanks so much!

After changing my # Cyls to 1 on the Zeitronics setup, and changing the Atmospheric Pressure from 14.7 to 10.2(for 7000' elevation) both signals are reporting accurately.

 

Glad I could help out, but next time I'll send more accurate info.
