Upgraded EKPM3 Fuel Pump Control Module

Fits Select E-Chassis and F-Chassis BMWs | Supports High-Performance LPFPs Like Walbro 525/535

Boost the reliability and performance of your BMW’s low-pressure fuel system with the Upgraded EKPM3 by Arc Terminator—a must-have for high-powered builds running large fuel pumps such as the Walbro 450, 525, or 535. Factory EKPM3 modules are notorious for thermal shutdowns under increased fuel demands, but our upgraded EKPM3 solves that issue with 22 amps of added current capacity and thermal protection enhancements.

🔧 Why Upgrade to Our EKPM3?

Factory EKPM3s use a stock Infineon half-bridge IC rated for only 33A peak / 17-18A sustained, making them prone to overheating and failure with aftermarket pumps. We replace this IC with a genuine high-output Infineon chip rated for 55A peak / 30+A sustained, ensuring your fuel pump receives stable power even under intense demand.

💡 FAQ

Q: Do I need coding?
A: Yes. Coding ensures proper communication with the DME. Use ProTool, E-SYS, or NCS Expert depending on your chassis.

Q: Can I run more than one fuel pump with this?
A: No. Factory 14-gauge wiring limits safe current capacity. For dual pumps, use a separate relay or Hobbs switch setup.

Q: Will this work with an EKPM2?
A: Yes, but coding is required. HW05 or lower modules are preferred for compatibility.

Q: Do I need additional cooling?
A: Only if you're using a Walbro 450 or larger. The integrated fan will auto-activate at 50°C.
