I just got my HPT software and have been following this thread and everything is good so far. The problem I am having is the factor to multiply by when running rich. I am using an AEM WB and needing to lean out for my WOT runs. If I multiply by the -1.02 as stated, it puts all the cells to zero. If I do the 1.02 it increases it as it should.
Should I actually multiply by .98 to get a small decrease in fueling.
