Wire Connections

Table detailing each wire color, its connection point, and polarity requirements.

Solenoid Hook Up Method

Basic setup instructions for connecting the solenoid to internal or external wastegates.

Parameter Setup

Over Boost Shutdown (obS)

Configures over-boost protection to prevent engine damage by reducing boost pressure.

Number of Set Points (nSP)

Sets the number of boost groups (1-6) to be active in the boost menu and live mode.

Number of Cylinders (CYL)

Configures RPM signal input based on the number of engine cylinders for correct RPM reading.

Scale (SCL)

Allows selection of pressure units for the readout: bar, psi, or kPa.

Bar Graph (bGr)

Configures the bar graph display to indicate pressure levels, adjustable to preferred maximum boost.

Boost Setup

Set Point (SP1)

Determines the duty cycle for solenoid operation at gate pressure, influencing overall boost level.

Gate Pressure (GP1)

Sets pressure below target to improve boost response and torque at lower RPM.

Sensitivity (SN1)

Adjusts how sensitive the e-Boost2 is to changes in the boost curve for stability.
