I believe that the Monster 620 always used a non-linear TPS.
One thing I noticed is that the maps on each ECU uses different break-points. the 59M uses 2.0, 2.5, 3.0, 3.5 then 4.0 degrees meaning 80 degrees end to end.(Last break-point is still at 82.0 in each case)
The 5AM uses 2.3, 2.7, 3.1, 3.5, then 4.0 degrees meaning 79.7 degrees end to end.
So it is possible that the TPS was adjusted differently from the factory to match this different range.
I'll need to check if there's any difference in the voltage.
