Well you left off the last 3 digit’s on the part number so I can’t double check it.
Typiclly a J series is safe to upgrade unless Ford has replaced it at some point with a newer production date model.
Question is why even put 3.4.x on it rather than the last 3.0.x release since the last release of both was within 30 days of each other?
Unless you’re planning on raising the APIM firmware/calibration to -Ex the only thing you’re getting is a prettier interface.
Oh weird, I know I put it in. It’s CDC

As per our hw db, you should be fine.
If you need higher certainty, you should take a picture of the APIM’s sticker on its back and share it with us.
