i will be switching my y8 into my 90 civic soon. i have a p28, will be doing the dpfi-mpfi swap, etc.. how do i get my y8 to run like stock with a p28 ecu. i want to use uberdata.. do i -4degress across the ignition table and then use my timing light to get 12 on the crank? i hear this thing about a p2p but i cant find a p2p rom or anything. any help would be greaty appreciated. thanks.
