Don't take this the wrong way, but if you guys are going to be profesionally tuning you should consider investing in some professional tools.

What have you tried to connect with?

I understand what you mean, I have tried fixing this ECU with Galletto and nothing, I know there is few people here that have the tools to fix my ECU.

Yup, it won't connect.

Thing is, I know what I did to make it stop working, I have PM'd few guys in here that can fix this kind of problems but never got back to me.

Out of curiosity, can you explain what, and how to fix it, so that others can learn?

Thanks.

Sure,

Don't ever try to start a 2004 A6 2.7T with immobilizer with an M-Box ECU.

Reason why I did this was because both cars have a Hitachi MAF and their ECUs should be interchangeable right? Well....they are not.

I guess I don't understand how what you did would affect a hardware function of the CPU?

If you look here:  http://oldwww.rasip.fer.hr/academ/courses/compproc/docs/chap13.pdf
it states:

Quote
The C167 enters BSL mode, if pin P0L.4 is sampled low at the end of a hardware reset. In this case the built-in bootstrap loader is activated independent of the selected bus mode. The bootstrap loader code is stored in a special Boot-ROM, no part of the standard mask ROM or Flash memory area is required for this.

im curious also why the immobilizer would have killed the ecu, seems odd.  How did you get the ecu connectors to mate up? thought they were different also.
