Ignition Retard
Launch Control uses ignition retard to help control power delivery during launch.
Configuration
Enabled
Whether or not ignition retard is enabled during launch control. This is used to help spool the turbo and can help make significantly more power.
However, on vehicles with torque converters, it can cause the engine to not make enough power to keep the RPMs up.
For these scenarios, you should use the Min Time and Stop RPM settings to help with this.
Amount
The amount of ignition retard to apply during launch control, in degrees. This is a list of values for each launch map. Negative values indicate retard, positive values indicate advance.
Example
| Launch Map | Amount |
|---|---|
| 1 | -15 |
| 2 | -25 |
| 3 | -35 |
Start RPM
The RPM at which to start applying ignition retard. This is a list of values for each launch map.
Min Time
The minimum time in milliseconds that the ignition retard will be applied once started. This is useful for scenarios where pulling retard will cause the RPMs to drop, but you still want to apply retard for a certain period. This is a list of values for each launch map.
Stop RPM
The RPM at which to stop applying ignition retard once started. If this is lower than the Start RPM, it will enter retard at the Start RPM and exit at the Stop RPM.
This is very useful with the Pressure Advance option.
This is a list of values for each launch map.
Enrichment
Additional fuel enrichment settings during retard.
Enabled
Whether or not to add fuel enrichment during retard.
Amount
The percentage of additional fuel to add during retard. For example, 20 means add 20% more fuel.
