Installing the Gauge The AEM Tru Boost boost controller gauge  requires a standard 2 1/16” (52MM) 
ounting hole and can be mounted in a flat  panel or most standard gauge pods.  The 
 two  wire bundles and a 5-pin connector.  The 5-pin connector 
connec t 
 to 
m
included cable contains
ts to a mating 5-pin connector on the  back of the gauge.  See Figure 2.  Connec
the black and red wires in the long 2-wire bundle to the leads from the boost solenoid.  
Polarity does not matter. Connect the bl ack wire...

Scramble Boost Connection (Optional) 
Scramble boost is activated when the orange wire is grounded.  Connect t\
he 
range wire to ground through a switch
o as shown in Figure 5.

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...

 
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 disp lay “ErS”.  The error code will not activate when the Tru 
Boost is on the off mode.  Note: The sole noid always has a small pwm signal to allow 
for fault...
