Good morning.

Hey guys, I'm having trouble updating the PCM (KK21-12A650-FA) in my 2019 Toureo Custom 2.0 Ecoblue 185HP. Forscan shows the availability of the new KK3A-12A650-BHM calibration, but when I try to download it, it says it can't find the file. Could you please tell me where I can download the new calibration file?

I want to update the module because the engine speed is very low immediately after startup (<750 rpm). I found information that the new PCM firmware fixes this problem.
Have a nice day :-)

I should note that I have purchased a paid Forscan license.

I doubt the engine rpm is low due to software problem.
It's more likely your alternator overunijng clutch has failed.
