Sorry for the late reply. I was noticing some weird pulls where VTEC would switch on late or not at all, or even switch off under WOT. Any ideas?KBuilt, you have a good eye 🆙. When you check the cross points (5250 rpm for a ftlb-hp same scale diagram) you see there is something wrong in the OP's diagram. These engine setups have optimal VTEC, depending on exhaust and intake setup, between 4000-5000 rpm. OP's engine VTEC switch point is beyond that crossing point, despite the 50° VTC capability, which largely can lower VTEC switch point speed by advancing VTC. Either a failure in the diagram SW or a failure in the tune of the calibration.
Motor has been bulletproof otherwise. Will try to find some dyno data for y’all to take a look at, steve at atomic race works in spokane wa gave me the tune & built the car, super reputable dude.
