Which ECU to use for my B16A2?

Wassup guys...I just recently got a B16A2 swap done off of a 99 SI. I have 2 ECUs right now...USDM P73 (ITR) and a JDM PCT (CTR). To all the ECU experts out there, which one should I go with?
Whichever one I don't use I think I'll sell.
Thanks

I think you should sell them and get a 99 SI ECU, since your maps/vtec crossover will be programmed to produce less power with that engine, since its not the right engine. I think the ITR ecu's run rich also, which would just make you run even richer.

99 SI ECU

depends on which car it is goin in. it is more work to make the 99 si ecu fot a 96-98 car.

Yeah...that's the prob. The swap went into my 97 EK. I have the SI ecu but I'm gonna have to dish out over $200 for an ecu jumper adapter. I think you're right about the richness as I'm not getting expected gas mileage.
But until I get the jumper, the question stands.
P73 or PCT? I noticed VTEC kicks in later for the CTR (~6200rpm), whereas ITR kicks in at around 5800rpm.
