Title: What Ecu allroad 2.7t Post by: streacy on August 03, 2019, 01:04:39 PM Hi,
My Ecu has had it, and I need to replace it. Can anyone tell me what Ecu I can? My car is an allroad 2.7t ARE engine, car was tip but I am swapping to manual now. Ecu was 551D me7.1 800bb (see image). Need to know what Ecu will work.

http://files.s4wiki.com/stock/part-numbers.txt Is there some reason you are avoiding 8D0...551M? Title: Re: What Ecu allroad 2.7t Post by: streacy on August 04, 2019, 03:08:18 AM Thanks for the link, I know of a 2.7t BES a6 local breaking. On your link it shows as me7.1.1. Will this work? Thanks
Not avoiding 8D0 551M, if there is one available I will buy it.

Not sure what that ECU is for.
If H, yes 7.1.1 Title: Re: What Ecu allroad 2.7t Post by: streacy on August 05, 2019, 04:02:37 AM Your ECU is marked D not H? Not sure what that ECU is for. If H, yes 7.1.1 Yes my original ECU is 551D me7.1 for ARE allroad but there is an A6 BES in the locality for breaking but from your chart it reads BES is me7.1.1.

Title: Re: What Ecu allroad 2.7t Post by: nyet on August 05, 2019, 08:30:41 AM Can I reflash a rs4 k box to an Mbox to work on a 2.7t ARE? From your chart it shows that there should be no issue, can you confirm? Sent from my iPhone using Tapatalk It should work, the only issue is that the rs4 box has a few outputs the s4 does not (two vs 1 vvt outputs, intake flapper) but I'm not sure that is a problem.

Can I flash M-box to any 2.7biturbo ECU? And yust copy values of MAF and injectors from original ECU, if they are different Title: Re: What Ecu allroad 2.7t Post by: nyet on August 05, 2019, 09:20:35 AM Sorry for question, but didn't find right answer.

According to list above it is not 7.1.1 ECU. So it schould be no problems to flash a M file over it?If somethnig goes wrong, can it be restored it via boot mode with original file like i do on 1.8T ECUs? Title: Re: What Ecu allroad 2.7t Post by: nyet on September 15, 2019, 11:15:13 PM yes, except for immo and/or assorted coding issues which are trivial to fix
