7.6 Boost / VVT 7 ADDITIONAL ITEMS: BEYOND BASIC FUEL AND IGNITION CONTROL

The closed duty, open duty, lower limit, algorithm, and PID settings work in the same way as the primary boost

control settings.

• MAP sensor to target - When running in closed loop, the second boost control solenoid will not target the

main MAP sensor, as most setups that require different wastegate pressure from side to side also require

different compressor outlet pressures. You will need to deﬁne what the second MAP sensor is on the Generic

Sensor Inputs screen in the Advanced Engine menu.

7.6.9 Wastegate dome pressure control settings

This screen includes additional boost control settings only used when running dome pressure control.

• Empty wastegate off boost? - This controls whether the dome remains pressurized when no boost is

commanded, or if the outlet solenoid should vent the dome to atmosphere under these circumstances.

• Control method - Simple control pulses the solenoids in quick increments until the dome pressure reaches

its target pressure. PID uses a proportional, integral, derivative loop to adjust duty cycles to reach dome

pressure. This method is more complicated to tune, but can result in less overshoot if tuned correctly.

• Min dome target and max dome target - If using closed loop control, this sets upper and lower limits on

what dome pressure targets the MS3Pro can use to reach a given boost target.

• Enable test mode - If this is set, the MS3Pro will activate the solenoids and attempt to ﬁll the solenoid dome

to the target pressure. The engine must not be running to use test mode.

• Dome pressure target - Speciﬁes what pressure to target in test mode.

• Dome ﬁll output - Selects what output pin is used to trigger the solenoid that delivers pressure to the

wastegate dome.

• Dome ﬁll output min duty and dome ﬁll output max duty - If using PID control for the dome pressure, this

sets upper and lower limits for what duty cycles to use when increasing pressure.

• Dome empty output - Selects what output pin is used to trigger the solenoid that vents pressure from the

wastegate dome to atmosphere.
