Ive gone on a couple drive now to collect data in the VCM scanner and im starting to get confused. I've flashed the pcm a couple times and my Cobalt SSSC is starting to run better, but it seems that the 3d view of the primary ve table is looking strange. Im getting extremly high value during low rpm ranges. I have aem wideband 02 sensor, and it reads around a 15-17 afr at idle/low rpm ranges. When i load data in my histograms though i am getting percentages of 20-30% at low rpms. Since the numers are positive, they are increasing the value in the primary ve table in the VCM editor. This is consistantly happening every scan, and I cant seem to figure out why. If the wideband is reading afr value of 15-17; then it should try to decrease this by logging negative values in my histogram at low rpm ranges correct?
I have attached two screenshots to show what I am talking about. Any help or thoughts would be appreciated.
