it SHOULD be pin compatible. Title: Re: S4 B5 upgrade ecu from 512kb to 1024kb help Post by: eazydaz on August 15, 2019, 02:06:38 PM thank you

Because all of the known existing interesting things are for 1M ECUs. And no me7.1 is wideband.

My me7.1 12v vr6 with a 512 file is wideband lambda... uses lsu4.2 Bosch sensor And no me7.1 is wideband.
