Title: Passat ECU in Allroad - 3B0 907 551 AN - check sum error from hardware? Post by: vtraudt on October 05, 2016, 07:13:39 AM Car came with Passat ECU 3B0 907 551 AN hardware.
Scanned as 8D0 907 551 M (what looks like a Nefmoto downloaded tune, aggressive stage 2). I flashed a more conservative file (and EGR, SAI, EVAP, rear O2 deletes). Car started, drove over several days. Yesterday, car cranked but did NOT start. After lot of checking/trying (crank sensor, fuel, spark, etc) found: 16985 - Internal Control Module P0601 - 35-00 - Memory Check Sum Error a) can hardware cause the check sum error or is that only tune related? b) can the hardware be used for Me7.1 applications (2.7T, APB; 2000-2002 S4, A6, Allroad)?

Your bin has incorrect checksum. Search for "death code" to fix this. And checksum the file properly before writing. Title: Re: Passat ECU in Allroad - 3B0 907 551 AN - check sum error from hardware? Post by: nyet on October 05, 2016, 09:53:40 AM did you bother trying ME7Sum on it?
If not, why not? Title: Re: Passat ECU in Allroad - 3B0 907 551 AN - check sum error from hardware? Post by: f1torrents on October 05, 2016, 01:08:16 PM Also that ECU is for a 2.8
I have tested a 2.8 ecu in 2.7TT but there is no N75 controller hardware in it. Its "works" but not very well. I Title: Re: Passat ECU in Allroad - 3B0 907 551 AN - check sum error from hardware? Post by: vtraudt on October 05, 2016, 02:16:40 PM Also that ECU is for a 2.8 I have tested a 2.8 ecu in 2.7TT but there is no N75 controller hardware in it. Its "works" but not very well. I As stated, its a Passat 2.8 ECU. Came with the car, installed was a (assume Nefmoto download) agressive stage 2 file. Car ran, no terribly noticeable runability issues. The tune scans as an S4 (8D0xxx551M" tune. Only want to know if Check Sum error is tune or hardware related, and in the same context if Passat 2.8 V6 ECU should be used AT ALL for 2.7T.

If not, why not, considering that would answer your question

Post by: nyet on October 05, 2016, 02:20:50 PM in the same context if Passat 2.8 V6 ECU should be used AT ALL for 2.7T. You think the lack of N75 drivers isn't an issue (if, what he says is true)? I'd think it would be immediately obvious from a log. Title: Re: Passat ECU in Allroad - 3B0 907 551 AN - check sum error from hardware? Post by: vdubnation on October 05, 2016, 07:35:18 PM The ecu was flashed by an (real) mpps cable which was checksumed prior to flash.
Title: Re: Passat ECU in Allroad - 3B0 907 551 AN - check sum error from hardware? Post by: nyet on October 05, 2016, 09:04:55 PM I've seen files flashed with MPPS that did not have a proper RSA signature... pull the file and please post the output.
Title: Re: Passat ECU in Allroad - 3B0 907 551 AN - check sum error from hardware? Post by: vwmaniac on October 07, 2016, 06:17:38 PM I have flashed a Passat 2.8 1024byte ecu with allroad software before. No issues or codes maybe 512k ecu hardware is different.

It's very easy to see the problem in a log. Sent from my iPhone using Tapatalk Title: Re: Passat ECU in Allroad - 3B0 907 551 AN - check sum error from hardware? Post by: f1torrents on October 08, 2016, 11:42:46 AM http://nefariousmotorsports.com/forum/index.php?topic=7200.msg66717#msg66717
