E30 Speeduino Compatible DIY Kit

For newcomers to the world of Speeduino, it can be a challenge to navigate through the in-depth information contained within the forums, let alone sourcing the correct componentry from the scattered array of part suppliers.

So let us do the hard work for you!

These boards are designed to fit into your factory ECU/DME housing, to make for a clean install using the car’s factory engine harness.

Currently, this kit can be made to suit the following BMW Motors:

• M20

• M30

• M40

• S38

Each DIY Kit will come with all components necessary to enable any future upgrades you may want to perform such as:

• Individual Coil/Wasted Spark

• Sequential Fuel Injection (4 cyl only)/Semi Sequential Injection (6cyl)

• AFM-less intake utilising a MAP sensor (rated for 4Bar)

• And more…

It is recommended to prepare the following modifications for this ECU:

• Wideband Controller/Gauge (such as an Innovate LC-2)

• M5x TPS + Re-pinning TPS Connector to suit Motronic 1.3 pinout

• T-Piece Vacuum hose to plug into the ECU

• Convert injector harness to a paired configuration (Cyl 1-6, 2-5, 3-4)

To install the kit, you will need to open up the ECU in your car and remove the original circuit board and replace with this kit.

If you wish to run aftermarket injection/ignition or run AFM-less, modifications will have to be made to the housing to suit the external connectors and/or vacuum lines.
