i want to run a obd1 p72 ecu chipped to XS engineering specs, on my 99 prelude. Ive heard of people running stock p72 ecu's on prelude but it runs very lean on a wideband O2 sensor 14:1 and even close to 15:1. So im thinking with a chipped ecu with more fuel it will be safer. The main reason i want to upgrade is so that i can rev my motor out higher to get the most out of my crower stage 2 cams and upgraded portflow valvetrain. Please let me know what u think
