Rolling Boost and Engine Safety features are now available for CBA cars through your Pro-Tuner!

Rolling Boost:

This feature will allow you to maintain a set vehicle speed while allowing the engine to build a set boost pressure!  This function can be enabled at any speed through the combination of holding the accelerator pedal past the minimum required point (adjustable by your tuner) and holding the cruise control switch in the SET (down) position.

Rolling Boost will use ignition retard to generate boost and the throttles to maintain the target speed.  The driver will keep the throttle depressed (ideally WOT) and then release the cruise control switch to exit Rolling Boost allowing the car to accelerate with immediate boost response.

This feature does NOT use the cruise control system for safety reasons.  Therefore, in order to engage Rolling Boost, the cruise control system must be off!

Note:  Excessive heat is generated while utilizing Rolling Boost mode.  If it is engaged for extended periods of time (over 3-5 seconds at a time), damage to the engine, turbo’s, and/or other components may occur.  It is also advised that a cool down period is observed between Rolling Boost usages (if you are roll racing and enter into the mode for a few seconds and miss-time the launch, it’s not a good idea to immediately re-enter it).

Engine Safety:

COBB has created several custom tables that allow your tuner to set conditions on different parameters (fuel pressure, coolant temp, oil temp, STFT, and knock).  If these conditions are met, torque is immediately reduced by modifying the accelerator pedal position or APP input (lifting the throttle to a percentage designated by your tuner).  If Safety mode is entered and throttle is lifted, the condition will be reset when the driver returns the APP to below 5% input.

Fuel Pressure and Safety are two independently enabled and calibrated features.  They can be used together or you can use only Safety if an aftermarket fuel pressure sensor is not installed.

We are currently working on these features for DBA ECUs so it will be available soon.  An ATR release for these features will be shortly after.
