Default Vtec not working after ecu swap

So I swapped my ap1 engine out for an ap2 f22c. For a few months I ran the ap1 ecu with the ap2 engine and everything works but dont want to over rev and want the vtec to come in sooner like its made to do with this engine so I paid to have the ap2 ecu programmed to my cars VIN and now I have no vtec at all. Went back to the ap1 ecu and it works again. Why would this be happening. No CEL lights come in and the engine runs fine with the exception of no vtec. Bad ecu?
