BB4 prelude H22a7 swap questions..
So I've read the thread by thericepatch (very informative and well written, and the pics are a major help) but im new to hondas so some of it was a little over my head.. As mentioned, it's going into a BB4 prelude that has already been swapped from an h23 to an h22a4. I blew a crank shaft bearing and decided to swap to the euro R engine.. Ordered the engine and started doing my research looking for any problems I'm going to encounter while doing the swap. But im not that versed on honda Ecu's. Should I pickup a Euro R ecu? Is the normal H22 ECU fine? Am i overthinking it and there's no difference? I'm assuming there is because of the different compression ratio but maybe im overthinking it... Any help would be greatly appreciated. Thanks in advance.

There are difference but don't think you will have problems if already had a running h22a4. Not sure. If looking for ECU, should use a chipped P28 (or similar) and have it tuned. If currently have an OBD2 search on how to swap to an OBD1 ECU
