By attempting back to back acceleration runs or dyno runs, the learned values will influence the maps.
You can clear them with separate steps with diagnostic tools if you require.
The "Over torque situation" can be seen in this influence, but in this case of after several days (since switching), it was more likely triggered my a Air mass sensor spurious signal or similar. Unless you are data logging at the time or can repeat the fault, they are tough to track down. If it was days & > 200km's it probably has nothing to do with switching all.

Car stopping at 80Km/h crushing is serious and can be dangerous.
So is this mean that switching is not good? Does it need to relearn at every switch?
