Injector Duty Cycle PID
So I purchased HP Tuners Pro along with a NGK AFX wideband and have been playing with the VCM scanner and reading alot trying to learn as much as possible but it's going slowly. One thing that is driving me nuts is why can't I log injector duty cycle using the PID that is allready included in the software under user defined. The function line says [SENS.112]*[SENS.70]/1200 which should be correct, yet when I put this in my table display along with Engine RPM (SAE), INJ. Pulse Width Avg. Bank 1 and INJ. Pulse Width Avg. Bank 2, nothing is displayed. When I try add it to a histogram it tells me it isn't supported with the current loaded parameters. What am I doing wrong? I've searched but nobody else seems to have this problem, maybe I'm missing something stupid.

Well I'm not sure what I was doing wrong before but I got it working now. However the histogram still doesn't work and I thought it was because I needed a VE PID in my main table. So I added the GM Volumetric Efficiency PID and it was spitting out values of over 1200 at idle and the histogram still did not work. What the heck?
