I'm trying to use this awesome program for logging. It connects and reads the ECU info no probs,  but keeps getting an error when logging.  Its an ST10 with IMMO off, on the bench. BTW ,VCDS works fine with forced kwp2000.  I don't need to flash, just need logging.

anyone manage to solve the verify checksums tab crashing for win7? github thread doesnt look like there's progress. Don't mean to be greedy.I very much appreciate this awesome piece of software. I'm not a developer so I wouldn't know where to begin solving this.

this was the event report:

I have problem with Nefmoto flasher 1.9.4.3 via OBD. It refuses to write. Cable is blue kkl with 232RL and it works perfectly with other programs (writing with me7eeprom etc).
Whether the car's immo is enabled or not didn't make any difference, I tried both ways. Car is -00 Audi TT (1.8T AJQ)

Hello
I am not successful either with blue kkl 232RL

I use it for vag commander 1.4

maybe a chip ID problem?

can you read but not write?
cable speed in the configuration maybe


do you have mprog to see the details?

I try to help but I'm just a noob and mechanic Roll Eyes

pin 121 did not exist in the wiring harness in ecu connector, was empty i.e. there is no power. Looking for schematics of autodata it should have direct connection to ignition coils' black/violet wire, but it did not.

I don't have other ecu's to try...

However, with the china-clone mpps v18 cable and its program, I can write through the obd in this situation, so I'll use it for now until I try to add pin 121.

Reading is also not possible with the nefmoto program.

Nefmoto is working for me with 512kb ECUs, but with "some special procedure".

- turn ignition ON and connect to ECU
- select 400BB layout and file to write
- click write and wait for it to fail with messege "A communication error was encountered while flashing. Press Cancel to abort, or OK to continue after reconnecting."
- click OK and wait for it to disconnect
- turn ignition OFF and click reconnect

It will say now "THIS-IS-THE-RAM-PROGRAM-" in KWP info, get SecurityAccessPositiveResponse and start write.

I don't even remember how I came up with this, but it works for me every time for many years...

Thank you, this helped.

I got the writing to succeed when I waited a good moment after that dialogue (and pressing ok), and pressed the connect fast/slow init button again. it started writing!

I also tried turning off / cycling the ignition there like you suggest, but that prevented the operation.  

however, I get "erase report failed" errors, despite that the writing goes through and no problems occur.

even this functionality is enough and makes nefmoto a winner, but what could be the reason for those? I'm already fed up with the fact that mpps v18 is not 100% reliable, it randomly brickes the ecu, and has to be repaired via boot mode. I can't get the Galletto 1260 to work, it freezes in all operations, no matter what I try to do with it.  Undecided

I'm not 100% sure of what is going on, but the RAM program is what runs when the flash process totally fails... its basically the ECU running in a failsafe mode (from RAM) which means if it loses power, you have a brick.

For whatever reason, NEF can get the flash process to complete when the ECU is in that failsafe mode, but NOT when it is (normally) running out of flash.

Presumably its a minor bug in nef... not sure who is qualified to debug it

Nefmoto flasher doesn't recognize my cable. I have the one recommended in the cable thread (VAG COM KKL 409.1 AUDI/VW/SE​AT/SKODA Cable OBD2/II 409). I did try my mvpi and it picks up that cord. Any suggestions?

Hi folks.

I would like to share this fork repo https://github.com/ljscodex/NefMotoOpenSource

I just updated the master branch to run on NET8, if you wanna run the project and let me know if is working will be amazing, I have no RS232 cable to test it right now

Thanks! very much appreciated. opened an MR but need testers.

Would be good if we can get automatic builds with github actions.

Actually, also wondering what other issues this might fix https://github.com/NefMoto/NefMotoOpenSource/issues
