21 Drag race features
This menu gathers all options normally used in drag race applications. All
the time based features start after releasing the 2-step button which indicates the
moment when the vehicle launched.
21.1 Burnout mode
The Burnout Mode is a function used to facilitate the processes of warming up the tires and using the two-step.
When pressing the two-step button, the two-step function is activated. Once the button is released, the curves from the
Time-based RPM Control come to action, allowing the tires to be warmed up properly.
When Burnout mode is activated, it disables the standard RPM Limiter, instead the ECU uses this RPM limiter as
.
button for 2 seconds on any dashboard screen.
the value considered for the final ignition cut. But when the two-step button is being pressed, the value considered is the
one set for the two-step parameter. The values adopted for ignition timing retard and enrichment are the ones configured
on the two-step function.
After having warmed up the tires
21.2 3-step (boost spool)
The 3-step is quite similar to the 2-step function, however, with proper parameters and even more aggressive to
assist in the boost spool.
There are two ways to activate this function, one uses an external button (must use a white wire attached to a
button, usually on the foot brake) and the other is through 2-step button. In this case, you must press the 2-step button
and the 3-step will be activated until the engine reaches a predefined boost pressure, at this point the 3-step will be
deactivated and the 2-step will be activated.
It is possible to start the 3-step mode before the RPM rev limiter and to set a minimum TPS value to activate it.
If using an external button to trigger the 3-step, when it is triggered simultaneously with 2-step button, the 2-
step will prevail.
WARNING: when 3-step is set to activate by speed, its operation can be checked through the Page 1 of the
Diagnostic Panel, not the page 2, since you are not using an analog input (white wire).
