BMW 123d DTC's Help

[bondiblu]

Can someone assist me with explanation of DTC's 4C2F / 4C2E / 4C29 , ECU EDC17CP02, 1 series BMW.

There are some reports that these codes are generated because of bad mapping.

[bondiblu]

Yes I understand that part, but what is the meaning of the DTC's, what triggers them?

Probably tuner who is tuned make to many changes on maps :) I read somewhere that some guy is braging how he change over 100 MAPS to lift torque and horspower. He dont understand that the trick is to change less maps with better result in chip tuning.

I think these DTC's are regarding torque monitoring? Do anyone have a Damos for his ECU?

Yes mate , is about torque and u already know that . You have the aswer to your question in another forum . Don't forget to change all TQL and IQL and the % of deviation the car can have between level 1 & level 2 torque.

Yes I participated in another thread on another forum, but the answer was left open if you read the whole thread, its not entirely conclusive. This is not a trick question, I'm simply seeking
more advice from people who may have more input into this issue. % deviation as been modified, and I believe the TQL and IQL too, but for starts I'm not sure which is lvl 1 and lvl 2 torque, can you shed any light on these?
