hey just came here for some help.. just wondering on what to do.. just finished dropping an F20B motor into my civic coupe.. Now heres the question , which ecu do I stick with??? I have a p28 where I used an obd1 obd2 converter .. the ecu runs like *** maybe with better tunning I should get another program for the ecu. Since this nonsense occured should I stick with the stock OBD2 PCb 004 ecu that the F20B comes with.. please someone tell me the difference between both ecus because I want to get the max potential from this motor
