Vtec not engaging

[BLKCIVICPN0I]

I have a JDM B18c, before it would just bog when vtec is about to engage, now it just doesn't engage at all, it feels like fuel is cut off after 5300 rpm. Anyone know what could cause this? I'm using a CTR ecu which is a 1.6, would that be a problem? I didn't have this problem when I got the swap. The reason I'm not using the ITR ecu is because I can't find one that has the immobilizer removed. Any help would be appreciated. Thanks

Your VTEC engagment point might be set too low. Look into something like a VAFC, and go schedule some dyno time to tune it.
