Description

A PnP ECU for the BMW M44 engines.
This PCB will replace the original board in the ecu case.
Just open the the ecu case, remove original board and replace with this.
You will need to drill/grind some openings for the new extra connectors and vacuum hose.

It is based around the DIY-EFI CORE4 module and runs the Speeduino firmware.
There is an option to have internal wideband control included, this is done using the DIY-EFI TinyWB module.
You can choose to have just the controller, the controller and a harness, or the controller, the harness and a LSU 4.9 sensor.

There is an aux connector installed which allows extras such as

• • • Flex Fuel sensor input
    • External O2 controller input
    • Fan output
    • Clutch (Launch control) input
    • Boost control output

A short (30cm) pigtail loom for this connector can also be added to your order.

On the current batch, the AC button behaviour is inverted, this impacts AC idle up.
