Hi, I have one of your Speeduino Motronic 1.3 devices, plugged into my BMW E30 325i using stock wiring, distributor and injection and 60-2 trigger wheel.

I have been unable to get the engine to start.

Does the ECU have to use a specific version of the speeduino firmware and specific version of Tuner Studio?

Any advice on the engine constants will be much appreciated.

Best regards

Malcolm

No this doesn't require any special versions.
Did you configure the SJ1 jumper property? Post your tune please.
