Something I noticed, and maybe it's just this winders install being stupid, but if I read a file and want to over-write an existing file, the application hangs in the save file dialog box...

I have already implemented a fix for this, and it will be in the next release. Thanks for pointing it out though, as it took me a long time to track this down myself. Turned out it was a problem with handling UI events on a background thread and not the main UI thread.

Anybody else getting "no response was received for the Tester Present message" when trying to detect supported baud rates?

I think I know what is happening here. The ECU is not responding to one of the StartDiagnosticSession messages and that is causing the process to fail. I wrote the code assuming the ECU would always respond. I will add support for handling the case of no respose from the ECU for a particular baud rate to the next release.

The general reject to the security response is a red herring. The NefMoto software tries to negotiate security before and after starting the programming session. On almost all cars only the security negotiation after starting the programming session works. The one you are referring to is before starting the programming session, and is essentially guaranteeed to fail on all but a few types of cars.

Did the software just continually output "NegativeResonse RequestCorrectlyReceived_ResponsePending?" If so, then that means the ECU was trying to enter programming mode, but was never quite getting there for some reason. The ECU would have been trying to relocate the running code from the flash memory to RAM and was waiting until that finished. It looks like something was going on that prevented the switching to programming mode running out of RAM from finishing.

Do any other versions of the NefMoto software work for you in car?

Nope. Never got any other versions working. Tried a bunch of different drivers too.

Do you have a known good win7-64 driver?

btw 32bit xp works fine on my other laptop. I only have win7-home on the win7 lappy, so i can't do xp mode in a vm on it.

Also, see my other post about using that older ftdi driver... different error...

A few other people have sent me log files. It looks like some changes I made to negotiating timing parameters in version 1.9.3.0 broke connecting for most people.

So if the NefMoto software worked for you prior to version 1.9.3.0 and doesn't anymore, and the software always fails with negotiating timing parameters, then I hope to have a fix for you in the next day or so.

Actually, thats the problem; that laptop has NEVER worked in car, even with 1.9.2.x.... so I am not sure changing it back to 1.9.2.x or earlier will help...

Should I try 1.9.1.x?

In reply #48 in this thread on June 27, the log you posted showing the error that occurred right after accessing timing parameters should get fixed in the next release. Is there another error you are getting when you try to connect in car?

I tried to read flash from ME7.5 ecu on the desk using this tool. There is issue with security access request while reading. I think it was assumed that user would do this while ecu is connected with instrument cluster and immo is on. I decided to turn the immo off in the ecu to avoid the problem with security. I've successfully read ecu's eeprom, turned immo off manually in the dump, recalculated check sum for modified lines and wrote modified eeprom back in boot mode using the same 95040 tools. But the Nefmoto flashing tool still tried to send authorization request after immo was really off. And it received another response from ecu that "authorization is not supported" on the unit. It recognized this as erorr and failed to read the flash. I think if it skipped the request it would be able to read the flash. Is it possible to read flash without sending auth request in case when the immo is off? If yes, is it possible to make this configurable in the tool. Like "skip auth. request" option...

Definitely possible. Can you post the log file so I can see what is happening? If you open the NefMoto software, and open the file menu, there are options to open or find the log file.
