ok so i bought a EG hatch that already had a b18c1 swap and i know very little about the cars history. the price was a real steal so i picked it up regardless. i would assume the ecu is chipped or modified somehow because vtec doesnt engage until 5500. how do i determine what ecu i have? how do i know if its chipped and what kind of program it is? and then also wondering how do i determine if my engine is usdm or jdm... and if its obd1 or obd2, etc.
