Built for Cummins ISX/ISM/M11 platforms, this reconstructed ECM targets dependable electronic fuel and timing control after a controller failure. It’s intended as a refurbished/repair solution to get fleets back on the road without the new-unit premium. The housing and connectors are ruggedized for engine-bay conditions, while calibration compatibility supports standard programming workflows. Use it as a service replacement when diagnostics point to an ECM fault. Ideal for shops needing a known-good unit on the shelf. Priced at $540.00.
