Description

This is a universal engine management computer. It will not plug in to your car. It has no base map and we don’t provide one separately. It has only basic universal instructions. If you are an experienced car builder and tuner this may be the right system for you. Universal AEM wire harnesses in a couple of different configurations are sold separately. MWR does not provide tech support for custom installs; please see the AEM Electronics forums.

For Toyota ZZ and ZR applications, please see our EMS4 plug n play kits which include wiring, sensor and plug n play harness. MWR provides full support for these packages.
