Absolute Boost
As per the latest updates to GTR the VR30DDTT follows the use of Manifold Absolute Pressure (MAP) for all aspects of tuning the boost control. All boost target, boost limit and boost threshold values are all absolute values in Bar. Tuners will now find that all boost related maps and live data will give consistent readings regardless of altitude, and calculations will hold true in all circumstances.
To make tuning as simple as possible we have added the Boost Target - Atmospheric Pressure Compensation maps by default, this gives a consistent “boost” at all altitudes, but the result is that your MAP will drop as a result, and power will be reduced at altitude if using the default Boost Target Atmospheric Compensation map
Enable Special Features (Boost Control Related)
EcuTek Boost Control – Enabled by default when adding RaceROM Feature File (patch)
The overall enable for the RaceROM boost control strategy is set by default when adding a patch. Once the patch is added the RR maps for boost control are used as opposed to the OEM strategy, this cannot be disabled or unchecked.
Enable RaceROM Boost Controller
Overall enable for the RBC, enabled by default. If turned off the cruise switchgear will do nothing boost control related.
RBC – Same value in all modes
Forces the RBC setpoint to be maintained even when switching MapSwitch Mode. There is a limitation of this in that ALL modes will have a maximum setpoint corresponding to the lowest of the four values in Boost Controller Maximum.
Scale Boost Target by Atmospheric Pressure disable
Forces the RRBC to ignore changes in atmospheric pressure when calculating boost error.
