ECU software

Post by radek93 »

Does anyone know what the latest software is for Motronic 4.4 for the b5254t manual? Have there been any changes? According to the gtp chat, I have the oldest version. Apparently, the newer versions have better idle control, STFT control, and no longer have sporadic misfires.
