I have an LS/VTEC setup with a JDM Integra Type-R head, intake manifold and throttle body. Unfortunately my original swap forced me to use an OBD0 PR3 ECU. I need to get a chipped ECU that will extract maximum power from my setup. I did not want to get a Hondata or VAFC or anything like that. Is it suitable to use a PR3 ecu with a Type-R head ? If so, what is the best program to use ? Who can I contact ? Is it better to use an OBD1 ECU ? Is it okay to convert using a OBD0 to OBD1 harness ? Will I need to change my distributor and O2 sensors ? Can this PR3 ECU cause the car to lose power in the lower RPM bands (everyone thinks the car should be performing much better than it actually is - haven't dyno'd yet) ?
