If you go to APEXi's site, I believe the VAFC doesn't work with the F22's VTEC. You might want to get a SAFC instead.

Q: VAFC: Will the VAFC work on 4 cyl. Accords?
A: No. The VAFC will not work correctly on 4 cyl. Accord models. 4 cylinder Accords incorporate a slightly different method of VTEC control causing the engine to hesitate at approx. 5000 RPM when the VTEC engagement point is changed. The VTEC AFC will work correctly on 6 cyl. Accords.
