First question.. is the ECU and DME the same device?
Second question.. if they're not the same device, where can I locate the DME? I'm suspecting it has a bad ground connection and want to investigate it.
I think that a ground for the secondary air pump may have gone toast on my DME. What procedure would I take in order to test if this is true? Can I do it with INPA or do I have to test the ground manually on the pinout of the DME?
