Launch Control (Turbo Anti-lag)
All STINGER 4 ECUs offer 2 launch control modes. One for drag racing and one for rally racing.
Note: Anti lag can be disabled via any digital input.
Rally mode is designed for when the car is moving and approaching a curve. At this point the antilag function should be activated in order to keep the turbo spinning while the car is negotiating the curve. This will ensure minimal turbo lag when accelerating out of the corner.
When the throttle position signal is BELOW the pre-set TPS level AND the engines RPM is above the pre-set RPM level, the antilag function will be enabled causing the ECU misfire the Ignition in one of 3 fire patterns. The ignition timing and fuel delivery will also be adjusted according to the selected fuel and ignition trim percentages. This feature would be used in conjunction with an auxiliary o/p to energize a blow off solenoid valve to either bypass the throttle body, hold it open slightly or to blow air directly into the exhaust manifold near the exhaust ports.
