Title: Is there a ecu cross referance? Post by: Richharr on August 10, 2018, 08:50:52 PM I picked up 2 ecu’s to practice with, 1 that matches whats in my car and 1 that will be whats in the car when i do a swap. I’m trying to identify them further for propper pinouts so I can read them on the bench.
The first one I pulled out of a 98 a4 2.8 quattro 4d0907551ah The second one is 4d0907560ae Unfortunately when I search those numbers here I don’t get anything and when i use google I 30 pages of ebay and ecu repair ads. So for the future is there a wiki or pdf going around? I opened them up and googled every number i could find to no avail Title: Re: Is there a ecu cross referance?

Title: Re: Is there a ecu cross referance? Post by: Richharr on August 11, 2018, 07:44:22 AM I did find this, i’ll post it here in case someone comes across this thread in the future
So the first ecu I’ll assume is a m3.8.3 Second is me7.1 (if anyone knows how to confirm please post it for future reference) Title: Re: Is there a ecu cross referance? Post by: nyet on August 11, 2018, 09:23:17 AM If you have the images it is pretty easy to tell by looking for strings in them.
