Re: M3.3.1 413
6x1 map in 0xE35C (0xE364-E369) is lambda control switch off load limits. It follows RPM and if actual load is higher than map value, closed loop will be switched off. If you have been adjust K-value, that is one of many maps what must be rescaled. 0xE36A, 0xE378 and 0xE382 are also called lambda sw...

Categories 256-300
Categories numbering rolls over: When trying to use category 256 it acts like "Any category" and 257 starts from category 1, and so on.
It's not problem, i think 255 different categories are enough, but that may confuse users.

Re: Has anyone on here disassembled the 413 code?
If you are using 413 ecu, CEL should be on, when ecu is powered up and waits for crank signal. Ecu needs strong power supply, i'm using 15V / 6A from old laptop. 12V / 1A was too lame. Voltage should be something between 12...15V.

Re: incorrect checksum symptoms??
Car? ECU number? BIN number and XDF what was used to edit it.
As example 413 ecu with 623 bin only sets trouble code if checksum is wrong.
Most likely wrong XDF was used. ECU goes reset loop if map header data is broken. Wrong offset in XDF can cause this.

No, it is synced now with faked cam signal.
153624 -> 536241 it's same firing order, but it only starts from 5. I think this is something to do with 120 degrees different trigger wheel position. Maybe only BMW engeneers can say why this is changed.
