BMW E30 1987-1993 E30 325i / E32 / E34 MS3Pro PNP ECU aka MSPNP Pro Plug and Play Standalone Engine Management System
*Fits multiple BMW models:
- 1987-1992 325i (E30 Chassis with M20) *
- 1988-1992 735 (E32 Chassis with M30)
- 1989-1990 525 (E34 Chassis with M20)
- 1989-1993 535 (E34 chassis with M30)
- 1991-1993 M5 (E34 chassis with S38)
*Note: This does not fit BMW e30 325e models with the eta engine (except the 1987 “Super Eta”), or the 1992 E36 chassis 325i with the M50 (in 1992, the convertible used the E30 chassis, while coupes and sedans received the new E36 chassis). These used a different ECU design. Additionally, some European 325i models for the 1987 year used an ECU with a part number of 0 261 200 073 or 0 261 200 081; this ECU is not compatible with the stock wiring on these cars.
Also, this MSPNP may not work with automatic transmissions on the E34 or E32 chassis, which rely on the fuel consumption signal for the transmission computer. Automatic equipped E30s using a hydraulic transmission will work without issue.
