Adjusting/Activating Launch control and Flat Foot (no lift) Shift parameters

NOTE: OFT ROM's have a special patch for these functions use the definition files from the www.openflashtablet.com website downloads page (v4.01)

Launch Control (LC)
is a second RPM limiter that is active when the vehicle speed is below the Launch Control Disable Speed value; ignoring any clutch input.


Launch Control Disable Speed = Speed at which Launch RPM is disables;

  • Above this wheel speed, your REV limit will go back to your normal setting. (Default Setting = 6mph (approx. 10KmH)).


Launch Control RPM Delta = The amount of engine speed that is removed from your normal RPM limiter forcing the active rev limiter LOWER = Launch RPM 


LC Logic is as follows:


Normal Rev Limit - Launch Control RPM Delta = Launch RPM

  • e.g. With your normal Engine Rev Limit set to 7600RPM, and your LC RPM Delta set to 3600, and your active Launch RPM will be 4000RPM (7600-3600=4000).


To disable Launch Control completely, set LC RPM Delta = 0

Flat-Foot Shift (FFS) [aka No Lift Shit]:


This is another RPM limit activated that enables while the Clutch is depressed. There is no throttle position requirement <- for this reason it can activate on downshift.


Flat Foot Shift RPM Delta = The amount of engine speed that is removed from your normal RPM limiter forcing the active rev FFS limiter

  • E.G.: If your normal RPM limit is 7600, and your FFS Delta is 2000, your FFS RPM limit will be 7600-2000= 5600 RPM.  
  • To disable FFS set Delta to 0 (zero) in the table FFS RPM Delta using Romraider


While up-shifting with your foot on accelerator, RPM will be limited to 5600 RPM as soon as you depress clutch; even while your foot is depressing the accelerator. NOTE: There is no throttle position requirement <- for this reason it soley activate by the state of the clutch switch. 


If you accidentally hover/press the clutch even slightly while driving, this feature can sometimes cause issues on downshifts when you set the Flat Foot Shift RPM Delta to low.
