FCA alert

[majorgeneralZ]

I got an FCA alert in the Ford Connect app for PCM reprogramming (19B37), which seems to target the 1.5 engine. Just curious if anyone with a 2.0 or 2.5 got it too. Someone with a 2019 Fusion 1.5 said their dealer told them it's to reduce boost for overheating and longevity concerns, but honestly, the current boost already feels just enough, so Im not so sure Im on board with that change.

Yeah, that recall mostly targets the 1.5L EcoBoost, but a few 2.0 owners have seen it too. Dealers say it's about engine longevity, but yeah it might soften performance a bit

Why would they apply a PCM update meant for the 1.5 to other engines like the 2.0 or 2.5, could it be a mistake in the alert system, or is there overlap in the tuning strategy?

The dealer's explanation about reducing boost for longevity sounds plausible especially with smaller turbocharged engines but I can definitely understand your hesitation if you feel the current power is already adequate.
It's always a bit concerning when a software update potentially alters performance!

I would guess there's an overlap in the underlying PCM architecture or calibration strategies across different engine sizes.
Sometimes a core issue or optimization discovered for one engine, especially regarding things like emissions or powertrain longevity, can have a similar or related application to other engines in the lineup even if the specific calibration values differ.

Ive been wondering the same.

I mean, don't we get a choice on this?
