Saabs auto trans, esp and XWD system sends out limiters on the canbus depending on driving conditions and firmware revision.Originally Posted by Alexander
Some have a 350nm, some have 400nm.
To get past this you need to carefully adjust the torque coefficients for boost and ignition to "fool" the system into thinking the max torque number (in my case 400nm) is still the same but will allow for more boost. Very small numbers like 10% change gave drastic changes from 1,2-1,5bar so go easy when trying. I'd suggest changing 5% at a time.
Leave your max engine torque at the max allowable torque from TCM/ESP/ESP and adjust the coefficients.
