I am having a problem with a Gen2 in that it drifts up a little before taking off. I tried lengthening the brake pick time but it doesn't seem to make any difference. I know it's saving ok because when I reset the power the change is still in there, but the car is still drifting. I have set the brake pic time out to 3000 or 3 seconds with no change in the issue. As soon as the door closes the car drifts up a little then runs down, you don't notice it in the up direction as much because it's going up anyway. Anyone else experiencing something similar? It's possible we are missing a step in the saving process but I would think if it still shows our changes after we cycle the power it was saved properly.

Start with swapping out the load weighing sensors to see if that works. If t doesn’t, make sure the OAD Board is wired in.

Depending on the age of the GeN2 and what kind of drive used....
OVF Drive -> ALWcomp Corr (Correction factor for internally calculated loadweighing compensation torque).
Ultra/Global Drive -> Pretorque Trim (Pre-torque values to prevent rollback)
