CSL '0401' Program Binary Disassembly Notes

[SliM3]

Do the US emissions machines connect via OBD2 ?

In the UK we just have the pipe up the exhaust and hold engine RPM steady.

They check readiness monitors here in GA via OBD2.

If anyone is interested this http://www.kleinknecht.com/en/software_gredi4.htm appears to be the software that BMW used to testbed tune the S54 (and presumably other engines/DMEs of the era).

There's a reference to "Gredi" in one of the funktionsrahmen documents and I saw it and was curious and a bit of a hunt unearthed this. This also explains what I'd previously noted about the "B" canbus channels which appear to be for transfer of data. Pretty sure the CAN Control Protocol that Gredi uses fits the bill.

Wow, wild find

Looks like the pre-decessor of INCA (ETAS).
Nice find!

Have you found pieces of code that could potentially be used for live adjustments? From what I believe is that some ECUs put (part) of the calibration-data (program) in RAM (memory) and adjust the RAM values to live adjust the data.

Might sound more easy than actually program it that way.
