AEM UEGO Controller

AEM's Wideband UEGO Controller is also available in a gauge that includes a single-channel analog output with a Bosch O2 sensor in one unit!

AEM's Gauge-Type Wideband UEGO Controller features an LED readout and sweeping LED “needle” that changes colors as AFR changes from rich to lean. The unit's 52mm (2-1/16”) gauge housing fits in most gauge pods and can be remotely mounted virtually anywhere. No laptop required for monitoring!

AEM Digital Display Gauges

AEM’s digital display gauges deliver unsurpassed accuracy and visibility. Each gauge includes 24 color-coded (Red, Green, Yellow) LED lights that change from green to yellow to red for immediate reference to the measured parameter, and an integrated thee-digit display that reveals real-time operating conditions. AEM’s digital display gauges feature a standard 52mm gauge housing that fits in most gauge pods and can be remotely mounted virtually anywhere. Each gauge includes interchangeable silver and black bezels and black and white faceplates to personalize the look of your gauge—it’s like having four gauge designs in one!

Includes easy-to-install harness and sensor
Complete stand alone gauge requires no additional sensors or programs to operate
Ideal for both fuel injected and carbureted motors
LED displays provide precise reference to critical operating conditions and alert driver of potentially damaging operating conditions
Includes 0-5V analog output for routing to engine management system or data logger
Easy to read faceplates/displays are designed to complement existing AEM gauge styles
Included bezels and face plates allow you to personalize the look of your gauge

AEM Tru-Boost Gauge

AEM’s TRU-BOOST Gauge-Type Controller is an electronic boost controller that combines the simplicity of a manual boost controller with the added ease of adjusting boost levels through a gauge interface. There is no external interface required for set up, and it is fully functional right out of the box. There are no gimmicks or special software programs included. If you want more boost press the button on the right of the gauge face, and if you want less boost press the button on the left of the gauge face. It’s that simple, and IT WORKS!

AEM’s TRU-BOOST Gauge-Type Controller includes everything you need, including an on-board 29 psig pressure sensor, built-in Overboost protection with two timed shutdown levels, a scramble boost setting and a low-side output for a warning light. AEM offers a 75 psia boost sensor for high boost applications (sold separately).

AEM’s boost control solenoid (included) is the only one specifically manufactured for automotive boost applications, which means it won’t corrode and stick from exposure to rich fuel mixtures, it is pressure tested to 100 psi and includes -4 AN fittings to eliminate any chance of leaks.

No external interface required for programming!
Complete system includes harness, boost hose, on-board 29 psig pressure sensor (external 75 psia optional), boost solenoid, gauge display and all necessary fittings
Quick connect technology eases the installation process
Two user selectable boost settings with peak boost memory
Scramble boost setting allows user to momentarily change boost levels
User selectable Overboost alarm includes two timed shutdown levels at 10% and 20% Overboost
User configurable gauge includes 24 scalable LEDs, and interchangeable bezel, pin guide and faceplate to customize look of display
One (1) low-side output included for warning lights

AEM Serial Datastream Gauge

AEM’s Serial Gauge plugs into the company’s Programmable EMS and has the ability to read 19 channels simultaneously to provide reference for all outputs, including boost, AFR, EGT, H2O, IAT, knock, volts, RPM, vehicle speed, and more! Since it can read all channels at once, AEM’s Serial Gauge eliminates the need to buy a cluster of gauges, or you can link multiple Serial Gauges together to monitor additional channels or to divide your readouts across a few gauges.

The Serial Gauge includes a user-selectable LED display allowing users to set vehicle specific limits, warnings, display ranges and operating ranges. This unit runs the standard EMS datastream by default, and includes 12 preset channels and seven user-selectable channels that are custom-configurable through the PC interface, allowing you to monitor practically anything attached to a sensor. AEM’s Serial Gauge includes user-programmable MIN/MAX storage for EVERY channel and records MIN/MAX values even if you are not using the function—if it’s in the stream the gauge records it. Red, yellow and green LEDs and the center three-digit display are fully user-programmable as well, making this a truly custom configurable unit. Users can set alarms for each channel so that when the signal exceeds a value the Gauge notifies you by flashing all LEDs and switching to the channel where the value was exceeded. User-selectable qualifiers eliminate false warning lights, and the unit includes two outputs to trigger ancillary warning lights based on user selectable conditions. The Serial Gauge also includes user-selectable alarm priority in the event multiple alarms sound, allowing you to set alarm readouts in your order of priority.

AEM’s Serial Gauge includes interchangeable silver and black bezels and pin guides, and black and white faces for a customizable look. Quick-Connect technology allows you to install the gauge and connect the wiring separately for easy installation and less chance of damage to the circuit board. The Serial Gauge includes a harness, wiring to connect to the EMS, a daisy-chain adapter for linking multiple gauges to one EMS and software for a trouble-free installation.
