Best ECU for LSVTEC setup ?

[mdixonjam]

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) ?

Its best to use the ECU for the head you are using.

Your absolute best option is to get some kind of engine managment system. Hondata/uberdata/crome/turbo edit and then it won't really matter what ecu you start with and you can tune fuel/ignition maps specifically for your engine.
