BMW B58 in an E46 with ECUMaster EMU PRO-8

Base23 built this B58-powered BMW E46. AFTERFIX designed the electrical system for the swap, manufactured the harness and handled first start and calibration.

BMW B58 on EMU PRO-8

Factory engine components with standalone control

The goal was to run a B58 on a standalone ECU in an E46 chassis. The factory pressure and temperature sensors, actuators and electronic boost control were retained. The system needed to bring those signals together with equipment power and the data presented to the driver.

We designed and built a race harness for this configuration. Wiring and module settings were developed together so the ECU, power distribution, dash and driver controls could function as one system.

First start and calibration

The B58 was commissioned on EMU PRO-8 with the original engine hardware. After first start, we calibrated it and measured power at the wheels on the dyno.

Planning your electronics?

If you're installing a B58 or another engine in a new chassis, tell us which parts and controllers you've chosen. We can help you decide what to retain and what the build needs for wiring, start-up and calibration.
