    M156 "Wheel Torque vs VSS" Table. Experiences?

    Can anyone share experiences with the "Wheel Torque vs VSS" Table?

    I doubt it can be wheel torque. It must be engine torque. Wheel torque would be much higher after gear reduction and nobody would be able to go more than 20% throttle tops at low speed!

    Is this table in effect under normal conditions or only under certain conditions (eg. Race Start mode)?

    Presuming it is in effect under normal conditions and the unit conversion is correct in NM, This table is going to limit engine output until at least 130km/h. That doesn't seem right. Also why would they bother entering values up to 1350NM at high speed when the engine only makes 600nm?

    Any experiences would be greatly appreciated. My logging time is severely limited at the moment.

    i haven't had any issues when modifying or not modifying this map. currently mine is maxed out as i was troubleshooting another limp mode fault.

    nevermind...just saw this reply.
