AEM’s Tru Boost boost controller gauge is a stand-alone boost controller that features a three digit LED digital readout with 24 sweeping multi color LED’s, two programming buttons, and an on-board pressure sensor. The Tru Boost kit contains all necessary components, including an AEM high performance boost control solenoid, to install and use the Tru Boost. Contents: See Figure 1.
PAGE 3
Installing the Gauge The AEM Tru Boost boost controller gauge requires a standard 2 1/16” (52MM) mounting hole and can be mounted in a flat panel or most standard gauge pods. The included cable contains two wire bundles and a 5-pin connector. The 5-pin connector connects to a mating 5-pin connector on the back of the gauge. See Figure 2. Connect the black and red wires in the long 2-wire bundle to the leads from the boost solenoid. Polarity does not matter.

Scramble Boost Connection (Optional) Scramble boost is activated when the orange wire is grounded. Connect the orange wire to ground through a switch as shown in Figure 5. Switch ORANGE (SCRAMBLE BOOST) Ground Figure 5. Scramble Boost Connection Warning Light Connection (Optional) The Tru Boost will ground the gray wire when the alarm is activated. Connect the grey wire to a warning light as shown in Figure 6. Warning Light GREY (Switched Ground 1.5a max) +12Vdc Fused Figure 6.

External Pressure Sensor The Tru Boost is capable of reading boost levels up to 50 psig when using the optional external sensor kit. The 30-4351 sensor kit comes with an AEM 75psia sensor and a harness to connect the sensor to the Tru Boost. See Figure 9. Plug the single row 3-pin connector into the mating connector on the back of the gauge. See Figure 2. Plug the black 3-pin connector into the pressure sensor.

Alarm: (ALA - 30) Set the boost pressure at which the alarm will activate. When the alarm is activated, the LED lights flash yellow and the warning light output (grey wire) is pulled to ground. Spring Pressure: (SPr – 2.00) Enter the waste gate spring pressure(3psi less then your spring). The Tru Boost will keep the boost solenoid open from 1 psi until boost exceeds the selected value. This value can be adjusted to reduce lead in boost spikes or reduce spool up time.

Using the Tru Boost The Tru Boost has 3 running modes. In all modes, for manifold pressures less than 0 psig, the sweeping LED’s remain off, the gauge displays pressure in units of in-hg, and the displayed values are negative. In mode A, the gauge will output the duty cycle selected for boost setting A. The gauge will output the duty cycle selected for boost setting B when in mode B. In the “OFF” mode, the solenoid output is turned off. Press and hold the left button for 2 seconds to change run modes.

Error Detection ErP- If the external sensor is shorted or disconnected, the LED lights will flash red and the center digits will display “ErP”. The error code will not activate when using the internal pressure sensor. ErS- If the boost solenoid is shorted or disconnected, the LED lights will flash red and the center digits will display “ErS”. The error code will not activate when the Tru Boost is on the off mode. Note: The solenoid always has a small pwm signal to allow for fault detection.
