While using a simple mechanical boost tap (Open Loop Control) is a very popular boost control method, using Closed Loop boost control will offer more boost lower in the rev range, and therefore more useable power in the RPM ranges that get used most frequently.
Closed Loop boost control system is a more direct and responsive way of maintaining a flat boost curve as it puts the ECU in charge of the solenoid. A correctly programmed ECU will get the boost up quicker while still hitting the same maximum power output.
The beauty of using this system is that the more powerful your engine, the better it works. But we will let our resident tech guru talk you through this in the technical video below.
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 ...
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 ...
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 ...
A guide on how to use the Elite Boost Control Function for typical street or mild racing use. WHAT IS A WASTEGATE A wastegate, by its namesake, is a gate or valve, that lets waste gases of the engine bypass the turbocharger turbine. If no wastegate ...
The Open Loop table allows boost to be increased over the standard boost that the turbo and wastegate combination provides. The turbo wastegate solenoid will only activate when it sees positive manifold pressure. To setup the Open Loop table, it will ...
