Hello, Has anyone done any ECU mods to any of these types of cars? I live in Costa Rica where the majority of the cars are late 80's to early 90 models Hondas, toyotas and Hyundais (civics, accords, elantras, excels, tercels, camrys, corollas etc.). I want to know if these vehicles need a MAP/MAF or another type of sensor mod to allow for the MPG gain w/ HHO. Any help?? The difference between the MAP/MAF and the EFIE? which do I need?
