BMS Stage 1 N55 & S55 same unit?

s2k750 · 07-15-2016, 08:28 AM

I previously had a 2015 335 with the BMS stage 1 tuner. I know the hardware is the same from the 335 to m3. I've read conflicting information about the software being the same.

Can I install it or does it need to be upgraded?

Thank you?

The new ones are the same unit for the N20, N55, and S55. The system detects the model based on the sensor voltages. The older ones are not and not compatible with the S55.
