I have a 420i with engine failure

code N20B20B and engine replacement request N20B20A appears to belong to the 428i

When I installed it in the car it started normally. But the problem I'm having is the vibrator

I have a few questions?
1. The way to turn it into a 428i with the new engine is N20B20A low compression ratio

2. Will Remap improve the problem, or do I need to find a DME 28i to install
