What the ignition offset does
During a shift, torque reduction pulls ignition timing to take load off the gearbox. The Ignition Offset table adjusts that retard as a percentage, on top of whatever shift table is active at the moment. Use it to take out more timing in some conditions and less in others.
A good example is air temperature. On a hot day you might want a different amount of retard than on a cool one. Put intake air temperature on an axis, and the ECU scales the shift retard automatically.
Setting it up
- Both axes are yours to choose, and the table supports up to 3D mapping.
- The offset only takes effect if you set values; left empty, the active shift table is used as-is.
- It applies to whichever torque reduction table is active, so check your changes across every gear and shift type.
Start with small percentages and compare shifts in your logs. Look at RPM, timing and driveshaft or wheel speed to see whether the shift is smoother or harsher.
See the main torque reduction guide for the full function, plus shift, cut time and delay time for the related settings.
