Function to build boost while vehicle is at the start line.
Get even faster with the Power management system.
enable launch control
Enable or disable the Launch control function.
multi stage launch
Multi stage launch control can be used to set a lower RPM limit while staging. Stage switching is controlled by TPS or by switch inputs. Use the internal digital inputs function Launch control switch, enable stage for advanced configuration of activation conditions.
Note: Stage 3 input overrides stage 2 if they both are active.
How Launch control should be activated.
•Switch input - The digital input function Launch control switch, enable stage x needs to be triggered.
•Clutch input - The digital input function clutch switch needs to be triggered.
•Always active (disabled by speed) - Launch control is always active, but will be disabled when system senses a wheel speed above a certain speed (disable above speed below).
switch activation delay
Specifies the activation delay time (in seconds).
switch deactivation delay
Specifies the deactivation delay.
disable below tps
Specifies the disable TPS, TPS below this value disables the Launch control.
disable above speed
Specifies the speed (if available) which will deactivate the function.
Note: Requires a wheel speed sensor to be mounted and calibrated.
Specifies the Speed source to be used to disable the function.
Switch to stage 2 above TPS
Automatically switch to launch control stage 2 over the specified TPS angle.
Note: Default value of 0.0% means no automatic switching to stage 2.
RPM set mode
Specifies how to set the launch RPM.
•Fixed RPM - Sets the launch start RPM from a fixed value (launch start rpm).
•table - Sets the launch start RPM from a table.
•Lock rpm when "launch control switch" is activated - Uses a floating point launch start RPM, when the launch control switch enable stage digital input is activated, it samples that current RPM as the start launch RPM.
Launch start RPM
Specifies the launch start RPM.
Ignition retard RPM range
Specifies ignition retard range.
Note: Use a high RPM here to prevent the launch to enter the power cut/ignition drop (power cut) for a smooth launch control. If you want the launch to be as loud as possible, you want the system to actually drop ignition, but you need to be on a high turbo/exhaust valve budget...
Power cut RPM range
Specifies ignition drop RPM range, used to limit RPM. Starting power cut at Launch start RPM + Ignition retard rpm range + this value.
Specifies power cut mode to limit engine RPM.
•Ignition drop - Preferable use ignition drop which cuts ignition to limit engine RPM.
•Fuel drop - Some engines requires fuel to be dropped instead of ignition to limit engine RPM, but preferable use the ignition drop.
Specifies the drop mode.
•Progressive drop - Interpolates the cut % from 0% at the "Launch start RPM" to 100% at "Launch start RPM" + "Power cut RPM range"..
•Stepped drop - Does a 6 of 7 events cut at "Launch start RPM" - "Power cut RPM range", and 100% cut at "Launch start RPM" + 100rpm. <-- with this mode, a power cut range of ~600RPM is recommended.
•table - Uses a value from the table as the cut %, can be used to as a "fixed" cut %.
•RPM control - Uses a editable P gain and I gain parameter to easier get a stable launch RPM.
RPM PID Control P GAIN
Specifies the Launch control P gain value when the above drop mode = rpm control.
RPM PID Control i GAIN
Specifies the Launch control I gain value when the above drop mode = rpm control.
Specifies the maximum drop (cut) in percentage (0-100%) allowed by the Launch control feature.
Specifies how much extra fuel to be added during launch control. Normally used to reduce temperature inside engine.
Note: Do not add to much fuel to flood the engine, the transition from launch control to normal control can be disrupted by too much fuel in the system.
ignition retard mode
How the transition between regular ignition table and the launch ignition retard angle is done.
•Direct - Changes ignition advance immediate when launch start rpm is reached.
•Linear - Smooth transition from ignition advance table to ignition retard angles (below) using the ignition retards rpm range. <-- preferable use this setting for smoother transitions.
•Ign angle vs boost - Ignition retard table vs MAP value. Can be used to control boost on Launch.
•Ign angle vs TPS - Ignition retard table vs TPS value. Can be used to control boost on Launch.
•table for main ignition table - Uses a "fixed" ignition advance angle from a table, instead of retarding from the main ignition table.
Specifies the ignition advance retard angle (maximum) during launch control.
launch boost duty
Specifies the boost controller boost duty during launch control (if boost solenoid is used, and used in open loop mode.).
Note: The launch boost duty ONLY works in Open loop (simple) boost control.
