An easy one here – if your ECU has access to the ride-by-wire throttle, a clutch switch, an IMU unit that tells it the pitch angle of the bike (if you’re wheelying and by how much), and maybe some suspension travel info, then it’s a simple job to program a launch control algorithm. It knows you’re in first gear with the clutch in, and the twistgrip jammed open, so it can hold the engine revs around peak torque rpm.
As you let the clutch out, the ECU feathers the throttle valves open and closed to maintain the peak-torque revs, while also watching the angle of the wheelie. The computer dials in just the right amount of throttle opening to keep the revs at the right point for maximum acceleration, without flipping the bike. Once the throttle’s at 100% and the revs hit the redline, you change up into second and the job is done. PROS – impresses car wankers CONS – impresses car wankers
IMU’s are the key to launch control.
