What am I doing wrong here? I can't figure why I can't get this histogram to work. This is on a e67 PCM (Ecotec LE5--supercharged)

Go into Table Display, right click, insert.

Configure user defined

Insert: 100*([AUX.20121]-[SENS.121]/[SENS.121])
**where AUX.20121= my wideband plugged into the slot 1 on the interface***
**and SENS.121= afr Commanded

Commit changes, press X

Pull up histograms...click on configure histograms.

Choose a number(I chose 3) and then name your Histogram

Choose your newly created PID (MAF-Error), Units % min max -20/20

Commit changes...

AND I SEE NOTHING. Please steer me in the right direction.

Anyone? It's a simple AFR % error histo...I just can't figure out how to set it up

 

Got it into PE, and Commanded is not doing what it should be. Pay attention to frames

did you ground the Wideband in the correct spot as well? two wires should come to the hptuners module and they are specific to where they are supposed to be placed.

 

custom pid looks wrong, should be 100*([AUX.20121]-[SENS.121])/[SENS.121]

 

It seems to work okay. It's right on the money with afr readings. I'm coming home tomorrow so I can play with it this weekend.
