You either need to run a JDM ECU, add a VTEC pressure switch, or disable that feature in the ROM. I think also that motor uses a non-heated 1 wire 02 sensor (P08 ECU) so if you use a P28 you would again either have to disable the 02 heater circuit in the ROM or use a 4 wire 02. FWIW, a P28 should run it fine, but ideally a P08 would be what you would want. That or just tune it.
