You completely missed the point. You were looking for unknown differences, not mapped differences. If you find unknown differences, then the bin for an open loop idle application working right vs...

I was talking about using Tools\Difference Tool in Tunerpro, not comparing line by line by hand. This will list the differences between the bins and show what is different that isn't mapped in the...

You might find it interesting to compare the 2 bins and see what comes up different that is unknown. This would tell you how much different the bins are besides the stuff mapped in the xdf you are...
