BEGi is the USA distributor of the XEDE System for the Mazda Miata and MazdaSpeed. The XEDE (pronounced "x-eed") is the only user-programmable engine control system that works with the factory ECU for great performance and near perfect driveability. Every one of its functions has the resolution and flexibility to complement all factory ECU functions. The XEDE carries the tuning torch without inducing any compromise to performance or safety.

The XEDE is the most user friendly engine management available! It plugs directly into the stock ECU and requires no tuning.* The XEDE comes pre-programmed for your application.

Why the Xede is better than a full ECU replacement!

How does the XEDE work?
It is wired into a wire harness that plugs into the stock ECU. It intercepts signals to the ECU.  For example, by intercepting the crank signal, the XEDE can advance or retard timing. By intercepting the load signal, the XEDE can make fuel mixtures richer or leaner. It remains under closed loop during idle and cruise, and goes open loop under boost. The MazdaSpeed Miata (MSM) XEDE also allows the user to control the boost levels.

Installing the
XEDE....
This is probably the easiest aftermarket performance part you will ever install on your car!  The hardest part is installing injectors, and that, too, is not difficult. Once the injectors are installed, plug the XEDE & wire harness into the stock ECU. Turn the key on. Turn the Key off. Start the engine. Rev the engine, watch the LED light turn green, and you are ready to drive. The MSM requires a new wire installed to the boost solonoid.  It's so simple, even Stephanie could install the injectors and figure it out!  No broken nails either.

Practical Information...
What is more practical than get in and drive? Forget tuning the car every time you drive it or the weather changes.  Short of getting struck by lightening, the XEDE won't fail.  It will be the most reliable piece of hardware on your car.

The
XEDE cannot change the rev limiter on any Miata.

The
XEDE can be used on ALL Miatas.

The MazdaSpeed Miata XEDE will illuminate the check engine light. It changes the stock ECU boost and TPS signal. Please contact us for more information on OBDII inspection.  The MSM XEDE comes with 440 cc Injectors.

The 1999+ turbocharged and supercharged Miata's have passed OBD II and Emission Inspection in Texas.

The XEDE has been installed on the 2006 MX-5, MazdaSpeed 6, 1.6L Miata, and MazdaSpeed3!

The XEDE Harness also comes wire for dual map switch, wideband O2 sensor integration and boost control.
