need advise where to start

I have a E36 325i m50b25tu with 413 ecu has all the m54b30 internals.
car is running nicely but under heavy load starts to lean out.

which bin file can i use to start at and which xdf file do use.
please be kind I am still learning and want to understand the tuning side of this thanks

Download the Bin and xdf file for 413 from the download section and start experimenting

Similar situation here, M52B28 with a 413. Car is running VERY RICH with an older Dinan powerdyne supercharger and Dinan software. I bet it's supposed to have one of those Turbotronics magic boxes on the MAF signal wire...

I used TunerPro with the Ostrich on OBD1 Mitsubishi ecus in the past. They had full disassemblies of the code to work with and a plethora of serial port diagnostic tools.

Is there no ALDL style RS232 diagnostic protocol for these Motronic ECU's? This dead-reckoning style of tuning is pretty crude.

Good luck roadrager!

you can use a snap-on scanner to watch data or the moates.net ostrich has live data tracing.
