I wanted to ask if it's possible to update the PCM L1T1-12A650-LA (calibration L1T1-12A650-GE and strategy L1B1-14C204-GE) in my Fiesta MK8 (1.0L Ecoboost 95hp, 2020 model) to MK8.5 software.
The reason is that I retrofitted the fully digital IPC N1BT-10849-FAF and managed to unlock the Performance Screen. Unfortunately, currently only the coolant temperature is displayed correctly (and the others are, I think, initialization values), and I've heard that updating the PCM to MK8.5 software is sufficient.
Or does anyone know what other things are needed?
I would be very grateful for any help!
