Title: VAG DCM3.7 Checksum Post by: nano on December 02, 2016, 08:00:17 AM Hello, looking for smart guy to do a collaboration for find CKS on this new ecu. Looking also for good info :)

Title: Re: VAG DCM3.7 Checksum Post by: prj on December 06, 2016, 02:32:22 PM There is a Russian tool that flashes them. I have it.
They say it does checksum too, but I have not been able to test. Title: Re: VAG DCM3.7 Checksum Post by: IamwhoIam on December 07, 2016, 01:09:55 AM My bad, I thought he was talking about DCM6.x from mk7 Golf 2.0 TDI. DCM3.7 is dead easy to flash, I can do it with my own tools, but I've never looked into checksums for them. They do have RSA though, so I'm not sure what can be done and how.

Not aware of any publicly available major tools that do this.RSA should not be a problem on these if they are SH70xx based. Title: Re: VAG DCM3.7 Checksum Post by: IamwhoIam on December 07, 2016, 09:10:34 AM I said "my own tools", where does it say "publicly available tools"? I hardly ever use any of the publicly available tools nowadays, although I have most of them since back in the day.

Fgtech works should Ok they say.. Verzonden vanaf mijn iPhone met Tapatalk Title: Re: VAG DCM3.7 Checksum Post by: prj on December 07, 2016, 06:10:10 PM I have it too but problems with checksum.

Title: Re: VAG DCM3.7 Checksum Post by: turbojohan on December 08, 2016, 01:24:34 AM yes.
Tried all kinds of small mods and all same problem. I can sent you file if you want to test something. Title: Re: VAG DCM3.7 Checksum Post by: prj on December 08, 2016, 01:55:25 AM If you change 1 byte and then get the issue it is for sure a checksum problem.
But if you are able to flash the ECU with a modified file and actually have it boot up (exit bootloader), then I would think the software can be patched to kill checksum checks. Title: VAG DCM3.7 Checksum Post by: turbojohan on December 08, 2016, 03:32:38 AM Prj, i've sent you an email.
