I just ordered a D16A for my 00 civic. It has a P2E non vtec ecu in it. The motor is coming with the harness and a PEM ecu for auto trans (pretty sure its from an HR-V). Am I going to be better off doing a auto to manual conversion on the jdm PEM ecu so it keeps the 4800 RPM vtec point or better off buying a P2P manual ecu? If I did the P2P manual ecu can I use a vtec controller to move the turn on from 5500 down to the 4800 it should be at for the D16A? Last honda a was doing mods on was in my teen years in the 90s..
