Checklist Launch

This guide shows the recommend method to configure Launch control system. Clicking each item (M1 Tune v1.5 only) will select the item and allow you to enter the required information. Once an item has been selected the help, for that item, can be displayed by hitting the F1 key.

This system aids initial take-off by means of ignition retard, engine speed limiting, electronic throttle control and boost aim control. It also provides fuel volume trimming to assist exhaust cooling.

Engine speed limiting during launch uses the Launch Engine Speed table and Launch Engine Speed Margin . The primary means of control is ignition retard.

While Engine Speed is above launch Launch Engine Speed, the Launch Ignition Timing Limit Advance system attempts to control engine speed using closed loop control of ignition timing. If Engine Speed exceeds (Launch Engine Speed + Launch Engine Speed Margin), a hard limit (ignition cut or/and potentially fuel cut) is applied. This allows turbocharged engines to develop boost pressure prior to launch.

The activation state of the launch system is reported by Launch State and further information about why launch is inactive is reported by Launch Diagnostic.

The following conditions must all be met for launch to activate:

• Launch Mode must be Enabled.
• Exhaust Temperature must be less than Launch Activate Exhaust Temperature. If Launch Activate Exhaust Temperature is set to 0 this setting is ignored.
• Coolant Temperature must be less than Launch Activate Coolant Temperature. If Launch Activate Coolant Temperature is set to 0 this setting is ignored.
• Vehicle Speed must be less than minimum vehicle speed axis site on the Launch Engine Speed table. This condition is ignored if the vehicle speed axis is not enabled.
• Throttle Pedal must be greater than Launch Entry Throttle Pedal.

Launch will exit if any of the following conditions are met:

• The engine is stopped.
• Vehicle speed axis of the Launch Engine Speed table is enabled and Vehicle Speed exceeds the maximum axis site value.
• Throttle Pedal is less than Launch Exit Throttle Pedal.
• Exhaust Temperature exceeds Launch Activate Exhaust Temperature. If Launch Activate Exhaust Temperature is set to 0 this setting is ignored.
• Coolant Temperature exceeds Launch Activate Coolant Temperature. If Launch Activate Coolant Temperature is set to 0 this setting is ignored.
