I have an O7 Supercharged LS7 magnacharged vette, built motor, heads/cam, long tubes, etc. Did a fuel system, 2 bar map custom os (speed density only)
Anyways I created the custom PID (mentioned here http://www.hptuners.com/forum/showpo...41&postcount=7 )
Tried various histogram and configs, tried creating the histograms from scratch. Created
EQ Err is the abbreviation for the chart
Pick % as the
100*((([SENS.120]/14.7)-[PID.68])/[PID.68]) is the formula
Made sure I'm logging everything neccesary in the table.
I spent hours with the car on this, and no matter what when I start scanning I get the "This Histogram is not supported with the current loaded parameters."
I made sure I'm logging analog1 (aem wideband) and I can see accurate wideband data in the scanner. And all the other values required in the histogram.
I've searched the forums, and I feel like I've tried this every which way.
Shooting blind over the course of the day I got this car dialed in fairly well, but it's not very smooth. It drives well, afr is solid, car is making 700+ whp, but I still have some afr swings and whacky fuel trims in a bunch of places. I really want to get this dialed in on the street/dyno with the functioning histogram.
