Not really, on the I4 if VTEC engages around 4900RPM's that's when it switches to the higher lobe which demands more oil pressure. But if your car is low on oil, it won't switch over and VTEC will not engage. Thus, the reason of not revving past 4900RPMs in park or a drive gear
...the engine will stay on the low cam if the oil pressure is low. The neutral rev limiter has nothing to do with oil pressure, I already explained why that's there. That's totally seperate, enough of that.
Haven't you ever driven your car when it's cold and needed to swing the tach up to get out of a tricky situation? The engine just doesn't hit VTEC engagement point and stop, it just stays on the low cam and it feels gutless.
