Here at Brewed Motors we not only sell AEM engine managment systems we also use them in all of our shop builds. International customers from the furthest corners of the earth use Brewed Motors tuning services, both live dyno tuning as well as E-tunes with full dyno results. All Brewed Tuning services also come with specialized customer training to teach the ins and outs of the AEM tuner software, providing the customer with the knowledge needed to properly data log and monitor the engine/ems. 

AEM’s EMS-4 Universal Programmable Engine Management System is more powerful than its predecessor. In addition to more robust hardware, there are several improvements over the original EMS, noted in the chart below. This is AEM's new Universal Standalone ECU designed for 4cyl engines built off of the same platform as the popular Series2 Plug n Play EMS. The EMS 4 is a complete standalone ecu that will control, ignition, boost control, fuel control, knock control, idle, nitrous control, and everything else. If you have any questions or reqests regarding the EMS-4 or set up/tuning do not hesitate to contact us. On top of providing custom wiring harnesses Brewed also supplies "start up maps" or "base calibrations" tuned to your engine build.

Legal in California only for racing vehicles which may never be used upon a highway.
