Yes, that would be one approach. An even better approach might be to search, in turn, for what sets the individual Brakeforce_ist_VR, Brakeforce_ist_MR, etc. variables, and in turn what sets them, and so on and so forth, until you arrive at some primitive expression that, I bet, will also refer to some sort of constant. But yeah, at the end of the day the value assigned to those Axle_Brakeforce_X_Y variables I mentioned originally is all that matters.
Looks like they're set to:
(L.L.Brakeforce_ist_MR) (L.S.Timegap) 1.66 * 33000 * - 0 max (S.L.Brakeforce_ist_MR)
Same goes for VL, VR, ML, MR, HL and HR
So in this case I can change them all to above 1.66 or should I change the 33000 number?
