blundar Author

The XE5 ECU is a specialized race-spec unit developed for the Mugen ZC engine platform (circa 1988–1991). It is derived from the PM7-0330 hardware architecture.

Important

The XE5 is a dedicated "race-only" calibration. It lacks support for an O2 sensor and disables the majority of standard factory sensor diagnostic checks.

Hardware Overview

The XE5 utilizes the PM7-0330 PCB layout. Because it is designed for closed-course competition, it omits the circuitry and logic required for closed-loop fuel control.
