Looking at the DME's available for my 00 323, there is the standard flash (Euro 3 equivalent) and the ones marked EU2 are for lower power output or low compression motors.

The one is marked "Catalyzer Preparation=Yes". Is that the cat-less EU2 tune?
You don't want any flashes marked for low power/low compression.

I know my tune number, there are at least 3 that can be used on my 325. If you aren't sure, don't flash.

For a MS42 323, you may want to consider 12141430440

For vehicles with:
EU2 exhaust emissions standard (S168A) = Yes

It's amazing to me that a non M E46 is such a beautiful car but the E46 M has never done much for me.
