I already told what to do earlier. You have to disable monitor2.

That's what I am doing right now, but I would like to understand the root cause of the problem, I know that there is a workaround for this but I find it strange that 90% of the tuned cars out there don't produce this DTC while the others do, some even mention that it is more common on cars manufactured in 2000, which sounds bullsh** but still Smiley
I also would like to know what can actually go wrong if the ECU is not going into limp mode because monitoring is disabled.

Thanks

Ok well that partly-bricked my ECU. Car starts up, but shuts down about 5 seconds later while the idle is dropping up and down. The NefMoto flasher can't connect anymore nor VAG-COM and the EPC light is blinking.
I've doubled checked the file I flashed the ME7Checker says it's OK! I guess I will have to bench flash it ..

masterj, can you please look at the file which flashed fine but prevents re-flashing and causes EPC blinking?
it is available at http://blade2k.humppa.hu/failed_torque_disable.bin
I would love to know what broke it.

Ok the ECU is live again after bench-flashing, now i gotta figure out what's the problem with the file Sad

Are you 100% sure that your map definitions are correct?

Give me original file bin I'll try to help you... P.S> write addresses of kfmiop/kfmirl and all the others that I wrote to edit... (I'm using winols so I can't open xdf)

Okay so here are the addresses:

KFMIZUFIL @ 0x11599
KFMIZUOF @ 0x11619
KFMIZUNS @ 0x115D9
KFMI_UM @ 0x14098
KFMPNS_UM @ 0x141A9
KFMDZOF_UM @ 0x14129
KFMPED_UM @ 0x14169

The original bin is available here: http://blade2k.humppa.hu/8D0907551M_dekaIV.bin

The failed bin file is: http://blade2k.humppa.hu/failed_torque_disable.bin

This way you can probably compare it.

Thank you!

Exactly. I'm not a fan of doing all the 00 0xff crap people are just blindly telling you to do.. but it is all you can do unless you are willing to do a bit of legwork with ME7L and the FR....

For example, like I did here...

Sure, once I get ME7L working because I can't get it to connect to my ECU with none of the connection methods it supports.

The problem is you are modifying maps outside of what your tool will checksum, it is likely one of the *****_UM maps. This checksum failure causes the ECU to run and cycle the throttle body, with out the ability to be reflashed.

Oh that makes sense, so I guess the MTX tuner-pro checksum plugin cannot handle it. I guess I should contact them so that they can look into the issue.
I will try your file as soon my galetto cable arrives so I can revive the ECU if needed. Is it going to be possible to modify your file (other maps than the *_UM ones) safely without freaking out the ECU again with a wrong checksum?

Thanks
