what engine do I have? (Southern California USA)

4cylenjoyer · 03-26-2023, 07:08 PM

I have a 2019 330i U.S spec. I am running a TT piggyback tune, but recently unlocked my dme,changed sparkplugs and ordered a catless downpipe and will soon move over to BM3. Anyways, I am confused on all the engine codes and which engine is the best for tuning capabilities. To my understanding the b46tu has the strongest internals for U.S spec. When checking online (bimmercat.com) and other vindecoders it says I have the b46d (b48b20O). But also when I google “is the b46d same as b46tu?” It says they are, so I am super confused…

Also correct me if wrong but from strongest to weakest it goes. B46e hybrids, b46tu, b46 gen 1. And for eu spec just change “6” to “8”
