But if your coolant is keeping the oil too cool it wont activate, will it? I also thought that VTEC wouldn't switch to the high cam when the engine is cold as a safety feature.

I have found this to be true, even after 5 minutes of driving down a hill on a cold night, sometimes vtec won't engage until it's warmer.

You probably don't want to be driving it that hard till it's warm anyway. The pistons, piston rings, and bore all change shape at different rates as they heat up. Your engine isn't actually tuned, or running properly, until it's warm.

I don't intend to, normally five minutes is heaps, but this time I got to the bottom of a long hill, at the intersection below decided to give some berries and nothing to show, obviously I noticed immediately and barely hit 5k and looked at the gauge and realised what happened.

Overall speed wont change,

If you have a stock airbox take the top cover off and let the car warm up.

Once its completely warm go in 2nd gear and at roughly 6kish youll hear vtec kicking in (deeper sound).

If you can put your phone on the dash and close all the windows so we dont have air causing sound and record the sound.

Make sure the car is warmed up otherwise vtec doesnt work.

Basically it will feel like it's actually worth revving all the way to redline, don't expect a kick at all, just a smooth transition. However in cold weather it's more noticable.
