Boost Control
Boost Control Wiring
Options Output Type One Solenoid - This is the typical setup found on cars which are turbocharged from factory, as well as most after-market turbo suppliers Two Solenoids - This is most typically used when a pressurised gas is used to manipulate ...
Boost Control Corrections
Duty Cycle Correction Duty Cycle Overall Correction - When the Mode is set to Closed Loop this will be an overall negative correction to the Base Duty Cycle. When the Mode is set to Open Loop this will be an overall positive or negative correction to ...
Boost Control Long Term Trim
This node allows you to enable, disable and reset the long term trim learning in the ECU. Enable Long Term Trim - Enables the Long Term Trim control. LTT Min TPS - Long Term Trim control is active only when the TPS is greater than this amount. This ...

Closed Loop Proportional Gain
This table controls the sensitivity of the Proportional component of the closed-loop boost controller. Proportional is the amount of effort relative to the error from the target. The default shape of this table helps drive the boost level towards the ...
Boost Control Delay
This is the Delay Time between meeting all of the conditions for closed loop, and for it to actually begin correcting the output. This delay is to ensure that the boost pressure has stabilised before trying to making corrections. Typically around .05 ...
Closed Loop Target Pressure
Only available when Boost Control Mode is set to Closed Loop. This table sets the boost pressure that the tuner would like to reach. The axes are user configurable and up to 4D mapping is available. For this example, a Haltech Trim Module is used ...
Boost Control Closed Loop Base Duty Cycle
Only available is Boost Control Mode is set to Closed Loop. Due to there being more than one target value, the boost control solenoid needs to be pulsed at a different duty for different boost levels. This is achieved by giving the ECU a starting ...
Boost Control Open Loop Base Duty Cycle
Only active when Open Loop is selected as the Mode. This is the duty cycle to be used by the Boost Control system, and should be adjusted to reach the desired amount of boost. No boost target is used in Open Loop and the ECU does not make adjustments ...
Boost Control
The Boost Control function is used to regulate boost pressure by controlling the duty of a boost control solenoid. This in turn regulates the air pressure supplied to the wastegate diaphragm. Note: Due to the large number of pressure units, all ...
