5.6. Drop Mode

Specify the drop mode. Options include:

• Progressive Drop: Interpolates the cut percentage 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.
• Table: Uses a value from the table as the cut percentage, which can be used as a “fixed” cut percentage.
• RPM Control: Uses editable P gain and I gain parameters to achieve a stable launch RPM, used in combination with the ignition retard mode set to linear.

The RPM control mode makes the launch start RPM your launch target, meaning any drop mode will start earlier. Data from Bosch in 2023 indicated that the RPM control mode provided the most stable and consistent launch performance.

5.7. RPM PID Control P GAIN and I GAIN

Specify the Launch control P gain and I gain values when the drop mode is set to RPM control. These parameters fine-tune the responsiveness and stability of the RPM control.

5.10. Ignition Retard Mode

Choose how the transition between the regular ignition table and the launch ignition retard angle is done. Options include:

• Direct: Changes ignition advance immediately when launch start RPM is reached.
• Linear: Smooth transition from the ignition advance table to ignition retard angles using the ignition retards RPM range.
• Ign Angle vs Boost: Ignition retard table versus MAP value, which can be used to control boost on Launch.
• Ign Angle vs TPS: Ignition retard table versus TPS value, which 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.

Selecting the appropriate mode depends on the desired launch characteristics. Data from McLaren Automotive in 2023 indicated that the linear mode provided the smoothest transition and best overall launch performance.

5.11. Ignition Retard

Specify the ignition advance retard angle (maximum) during launch control. This setting significantly affects launch aggressiveness. Adjusting this parameter requires careful consideration of engine characteristics. A technical guide from Bosch in 2022 recommended starting with a retard angle of 5-10 degrees and fine-tuning from there.

5.12. Launch Boost Duty

Specify the boost controller boost duty during launch control (if a boost solenoid is used in open loop mode). This setting controls boost pressure during launch.
