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


Well, I'm using WinOls so I've fixed my chechksums, but if you modify maps again then you might experience same thing

I've managed to do some logging today (https://docs.google.com/spreadsheet/ccc?key=0AhrG40GHpr-hdDhzdEkyWllmRGkwLUR6czBaRGo5dnc#gid=0)
and it seems that i get into limp mode with torque monitor 2 when my IgnReatrdKnockControl (wkr_1-6) gets below zero.

Every tuned car is experiencing small knock unless you have very retarted timing... And that shouldn't put you into limp... Look for different factors

Ok so a negative value is okay there, i though it should only be positive.

Retarding spark means negative numbers Wink It only occurs when knock sensor pick up knock

You're nowhere NEAR logging anything that causes torque intervention.

Well I did some logging again with way more info and it seems that my EngineLoad is higher than EngineLoadRequested for a long enough time to cause the intervention. It happens right at the end of the logfile before I shut the engine down. Any ideas?
Thanks

Did you check s4wiki? There are lots of references to the various torque monitoring threads/messages here.
