    Antilag

    Hold cruise minus to run the antilag map. Release it to return to the selected map.

    Antilag reduces turbo lag by retarding ignition and adding fuel, so pressure stays up on the turbo even when the throttle is shut. On a Tangent Motorsport file it uses an extra ignition map. It only works when the file was built with cruise-control switching, and it cannot run at the same time as mapswitch mode. Map switching itself is described on the mapswitch page.

    How do you turn antilag on?

    1. Leave mapswitch mode. Antilag does not trigger while you are selecting a map.
    2. Press and hold the cruise-control minus button. Map 5 is used for the ignition maps for as long as you hold it.
    3. Release the button to leave antilag and return to the map slot you had selected.

    If antilag safety is enabled, the code turns antilag off even while the button is held, to protect the engine. Release the button and press it again to re-enter.

    What can be configured?

    A file built with antilag can expose these limits in the calibration:

    • al_acc_ped_thr. Minimum accelerator angle before antilag will trigger.
    • al_eng_speed_min. Minimum RPM.
    • al_eng_speed_max. Maximum RPM. Above this, antilag stops.

    Which map runs?

    Maps 1 to 4 are the normal slots: stock, daily, and performance. Map 5 is the antilag calibration. Holding cruise minus selects map 5 in every slot. Releasing it returns to whichever of maps 1 to 4 was selected.
