2014 BMW 435i MAP Sensor Calibration

Hello everyone, I have just installed a larger turbocharger and uprated the factory 2.5 Bar MAP sensor to a 3.5 Bar sensor. Does anyone know how I can calibrate this as i am getting a drivetrain malfunction at the moment? Thank you in advance

Hello,

I believe some of the tunes like BM3 or MHD have options to change that.

Do you have any of these?

If so the map configuration page should have an option to change.

If not you may need to rescale some tables and custom tune for it.

If you are getting a drivetrain malfunction, I would advise doing a scan and reviewing the fault codes 1st.

Regards,

Shane

I am doing a custom reflash myself on this vehicle so I don't have any of the mhd or bm3 stuff. If i don't have it, what maps and tables will i have to rescale for this map sensor to work on this vehicle?
