wrong forum, this is the CIS Injection Forum.
I'm not sure if this is the right area but here goes. I picked up an ecu for my 99.5 audi a4. It has an AMS chip in it. AMS is no longer in business. The ecu is a 558m. My old ecu was a 557p. When i hooked it up it idled fine but the oil light is flashing and my tach does not work. What do I need to do now? Any help would be appreciated.
