Hi,

I own a Subaru Leone with a Wrx EJ20G Motor in it, Competition gear box, Z4 Ecu with a stage 3 chip in it, Rear Wheel Drive.

I need help in wiring a Data Link Connector, OBD I or OBD II, I have no idea which wire goes where to the ECU. Can I get some help with this please?

Thanks,

Regards,

Amk.

He's running an aftermarket ECU though, would it matter?

I don't know of any aftermarket ECU that can run a standard OBD diagnostics port. But they all have some way of communicating with a computer to monitor and adjust it. usually a Serial or USB cable.

 

 

What are you trying to do?

He's right. I've never seen an aftermarket ECU with a trouble-code port like a standard ECU. They mostly all run the bog standard old-school printer-connecter style serial port right out of the ECU. Check it out.

sounds to me like a stock Z4 ECU with a chip. not an aftermarket. should be able to hook up the stock Slect monitor cable. however, you would have to have a JDM slect monitor, that would read the Z4 ECU. not to mention that it may not comm. with a chiped ECU.
