Just wanted to ask something real quick and i hope some one can clear it up for me so i will understand a bit better. I have a 90 ef with a 94 civic si engine swap that wasnt done completely, I have bought JDM$hit obd0 to obd1 harness ( they still had original ecu from 90 civic in it ) my friend is getting me a p28 computer for the civic will i have any problems what should i expect and is there anything that would be better than the p28, sorry for so many questions but i have had A1 volkswagons last 12 years so this honda stuff is totally new to me

 

pretty much just the ecu. it ought to already be wired for mpfi
