All AEM Tru-Boost gauge programming is done using the faceplate buttons and no laptop is required. AEM's specially designed Boost Control Solenoid and all necessary hardware is included.Program Two Boost Levels + Scramble Boost Setting - Program two boost modes for different levels of performance (up to 80PSIg internal MAP sensor), and program a time-based scramble boost setting that is controlled using a switched input. You can also turn off the controller and use the gauge as a display.Change Wastegate Open Pressure-Ideal for reducing boost spikes and improving spool up.Display Boost Levels in PSIg (PSI), BAR or kPa (PAS) -See your boost in the units you prefer, and scale the 24 outer LEDs to match your peak boost levels for the perfect sweeping motion.Set Alarms and Display Peak Boost-Set the 24 green outer LEDs to flash based on boost pressure so you are alerted to an overboost condition. A ground output is included for triggering an optional LED warning light. Select the "B" button to see peak boost level and clear the value using the menu.Overboost Protection Built In-Protects your engine from an overboost condition by shutting the boost control solenoid off until it is reactivated by you through the buttons on the faceplate.Integrated Error Protection-Alerts you to a fault if the boost control solenoid is shorted or disconnected so you are never left guessing whether the Tru-BoostX is operational.Datalog using AEMnet CAN bus-Outputting channels over AEMnet provides so much more than just boost pressure! Send 13 channels of data over a 2-wire connection, including boost pressure, peak boost, boost target, boost scramble duty, overboost status, wastegate crack pressure, boost control solenoid status and more.
