AEM’s Plug & Play Engine Management System (EMS) will forever change the way you look at and perform fuel injection tuning! This user-programmable system plugs directly into a vehicle’s factory ECU harness and requires no additional wiring or hardware. (Some adapting hardware may be required for non-factory forced induction vehicles.) Windows™-based software (2000, NT, 98, 95, ME) makes the task of copying, viewing and manipulating data as simple as a click of the mouse. User-defined templates are easily configurable and enable tuners to establish “quick keys” to any pertinent information during the tuning process.The AEM EMS’s infinitely adjustable software allows tuners to program virtually any combination of engine control, power adders and auxiliary devices, and accurately deliver proper amounts of fuel and correct ignition timing for ANY boost level or operating condition.

10 Channel Peak & Hold Injector Driver

Eliminate Low Response, High Impedance “Saturated” Injectors!

AEM is proud to introduce its external Peak & Hold Injector Driver module! This unit allows ECU’s that have a saturated injector drive circuit to trigger low impedance injectors with a true 4/1 Peak & Hold injector drive circuit.

AEM’s Peak & Hold Injector Driver contains 10 independent injector drive channels. Each channel supplies full battery voltage to a fuel injector for rapid current rise, in order to produce positive injector opening. When load current reaches 4.1A (amps), the injector driver reduces the load current to 1.1A and operates as a constant current source. This condition holds the injector open, and reduces system power dissipation. If the current fails to reach 4.1A within 5mS, the driver module automatically reduces the load current to 1.1A.

Installation is straightforward. Users simply hook the injector trigger wires from an ECU to the module, and then hook the output wires from the module to your injectors. Any number of channels can be used from one to 10.

AEM UEGO Wide Band Controller

AEM's Wideband UEGO Controller is available in single- and dual-channel modes, and is the most affordable UEGO controller available. The AEM Wideband UEGO controller has a very low current draw, and features both 0-5v calibrated output and 0-1v calibrated output to mimic the factory narrow-band sensor, eliminating the chance of a factory computer issuing a trouble code.

4 Channel K-Type Thermocouple Amplifier

AEM’s 4-Channel K-Type Thermocouple Amplifier provides laboratory-grade accuracy for virtually any on-board temperature measurements. This unit utilizes low-cost K-Type thermocouple amplifiers to measure multiple engine system temperatures with better accuracy and faster response times than currently available temperature-measuring alternatives!

The 4-Channel K-Type Thermocouple Amplifier is ideal for users who want to accurately monitor multiple engine system temperatures, including water, air, coolant, fuel, disc brake and more! Multiple channels allow you to use each amp to simultaneously read different system temperatures (one channel for EGT, one channel for CLT, etc.). Users can utilize ANY K-Type thermocouple including commonly-available miniature thermocouple connectors, and datalog the readings via an RS-232 serial data stream (programmable EMS not required for datalogging). This unit does not include K-Type sensors; however K-Type sensors will be available from AEM in the near future.

Unlike common single-channel gauges and amplifiers whose readings can vary up to 20° C from actual temperatures, AEM guarantees its 4-Channel K-Type Thermocouple Amplifier to read better than 1% full scale, even at the extremes of the temperature range! The unit achieves its laboratory-grade accuracy via a 100% surface-mounted PCB (printed circuit board) that has four differential temperature inputs fed into an A/D converter and fitted using a stage-three, eighth-order polynomial curve fit. The amplifier then compensates for this value using AEM’s on-board cold junction temperature measurement, and then sends the temperature outputs on feedback-monitored 0-5v analog outputs and an RS-232 serial data stream.

Gauge Type UEGO Wide Band 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!

Serial Data Stream Gauge

19 Gauges In One!

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.
