AEM's EMS-4 Standalone Engine Management System is the ideal standalone Programmable Engine Management System for modified four-cylinder race car applications.

The EMS-4 was created using AEM's powerful Series 2 hardware and includes all of its advanced features without the unneeded ancillary components.

The EMS-4 is universal and has all of the features you need and nothing you don’t (like AC, power locks, stereo, etc.) for dedicated 4-cylinder racecars, motorcycles, quads, side by sides or other race vehicles up to four cylinders.

The unit includes a 36-pin connector that is specifically designed to operate in harsh environments.

It is completely sealed, weather/shock proof and can be mounted anywhere.

The EMS-4 works with MAG or HALL crank inputs and can directly drive smart coils or an external ignitor such as AEM's 4-Channel Coil Driver (P/N: 30-2840).

EMS-4 universal wiring loom is needed (P/N: 30-2905-96), featuring colour-coded, silk-screened wires for ease of installation, and an integrated fuse and relay panel.
