The AMP Plug-N-Play ECU (AMP PNP) enhances your 1987–1993 BMW E30, representing the next step in the evolution of the trusted MSPNP-Pro platform. Built upon the robust MS3Pro Technology utilized in global motorsports, this ECU offers the same dependable reliability, sophisticated tuning capabilities, and proven performance that customers have relied on for years. Major usability and hardware upgrades have been implemented to simplify installation, improve expandability, and empower more potent tuning. The AMP PNP ECU is compatible with specific BMW models including the 1987-1992 E30 325i (M20, Manual), 1988-1992 E32 735 (M30, Manual), 1989-1990 E34 525 (M20, Manual), 1989-1993 E34 535 (M30, Manual), 1991-1993 E34 M5 (S38, Manual), and the 1987 E30 325 ‘Super ETA’ (M20B27, Manual). Crucially, this unit is NOT compatible with the BMW E30 325e, the 1992 E36 325i with M50, or European 325i models with ECU#’s (0 261 200 073) or (0 261 200 081). While compatible with BMW E30 models featuring hydraulic transmissions, automatic transmission control for BMW E32/E34 models has limited and unconfirmed compatibility. An optional, fully integrated wideband controller is available, utilizing Bosch-based technology and LSU 4.9 sensor compatibility to eliminate the need for external modules and simplify wiring for a cleaner, more reliable setup. The ECU features an expanded I/O with a new 48-pin options connector, offering 8 analog inputs, 4 digital inputs, 2 speed inputs, and 9 outputs for greater flexibility. Dedicated rear spark outputs facilitate easier Coil-On-Plug (COP) upgrades without complex repinning or harness modifications.
