PA: P72 OBD1 JDM Virgin ECU B18C $150 shipped
i got a question about my ecu...recently, i was using a p28 set up with an s300, then i got my orginal ecu which is a p72 with the newer s300...i see a difference when vtec pops with this p72...not a good difference. i cant feel or hear vtec pop anymore. but with the p28, i felt and herd the difference. is that because the p28 was tuned to certain specifications? or is it because im using a p72 on a b16a motor?
