Ok, just finished my 96 hatch, b16a engine and trans, no CEL's runs extremely smooth, i have obd2a with a p73 ecu, everything i sperfect about how it runs just Vtec engages at 6200, i was wondering if anyone had the specs on the p73 ecu, (Vtec Engagement, Rev Limiter) the ecu is great though, only uses the primary o2 sensors and it runs my b16 extremely smooth.
