AMP EFI MS3Pro - Line Lock Staging; Timed Retard after Launch; Speed Based Launch Control

7.8 Advanced Engine 7 ADDITIONAL ITEMS: BEYOND BASIC FUEL AND IGNITION CONTROL
• Hard limit - when the 3-step is on, above this rpm the hard limiter methods are used
7.8.11.5 Line lock staging When drag racing a car with a manual transmission, sometimes it seems like it
would be easier if you had three feet and three hands. Line lock staging automates brake release on a car with
a line lock. The MS3Pro will engage the line lock using the selected output when you trigger the button input
with a momentary switch. The line lock releases if you push the button a second time or when the launch control
disengages.
7.8.12 Timed retard after launch
If you have enabled “Timed retard after launch” in the Launch Control screen, this screen allows you to adjust
the timing immediately after launch. This curve specifies how much timing to subtract from the regular timing curve,
in degrees, as a function of the seconds after the launch control has been released.
7.8.13 Speed based launch control
The MS3Pro can enable launch control based on vehicle speed for rolling starts.
• Wheel speed based launch - Turns this feature on and specifies which VSS input to use. This speed input
should be on the non-driven wheels.
• Enable launch when TPS above - Specifies the minimum throttle position to use this feature.
