Haltech hasn't published detailed help text for this table yet, so here's how it fits into torque management as a whole. The driveshaft-based strategy compares how fast the driveshaft is actually turning against a Driveshaft RPM Target. If it's spinning up faster than planned, the tires are usually spinning, and the ECU pulls torque to bring it back.
There are two tools for pulling torque. One retards timing, set in the Driveshaft RPM Ignition Correction. The other, this table, cuts a percentage of combustion events. Cutting events removes torque faster and harder than retarding timing, so it's usually used as the stronger response when timing alone isn't enough.
Start with small cut values and lean on timing first. Heavy cut is harsh on the drivetrain and makes the car unsettled. Check the table's axes in NSP, then log driveshaft RPM, target and cut together and add cut only where the logs show timing couldn't hold the car.
The engine RPM version works the same way. See Engine RPM Percentage Cut. Setting up torque management for the first time? Book a free consultation.
