The signals to the engine warning light are provided by the Omex ECU on the Plus 4 and there is a little bit of wiring to organise. I'm not sure what they do on other models.

Heinz. The OBD2 port is connected to the original ECU, I suppose it is the same on the Plus 4 SS and the Baby Doll, consequently it shows a lot of errors. Isn't there an exception for small volume production?

I don't know but a bit of clever wiring would probably provide the signals required to the original ECU. It depends on just what it is that they need to see for the control.
