XEDE unit, Plug 'n Play Wire Harness for stock ECU - Harness fits my 2002.
XEDE is probably the best piggy back system for the Miata. I've used a couple of them and this is the easiest to use and the best installation thus far.
I was running RC 550's and the BEGI s4 kit with a GT2860RS at 13 LBS. I turned the boost up and popped my engine so I'm going forged with a stand alone. I'm not excited about the stand alone but due to the compression change I cannot keep the XEDE (or at least I don't think I can).
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. Some tuning may be required by the end user.
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.
