VTEC and AFR's

[abs0Lut]

So I've been so used to a straight pipe exhaust and easily hearing VTEC engage but now I got a res and muffler installed it's alot quieter and I can't tell if VTEC is engaging or not. I have a turbo b series where full boost hits at very low rpm. Would you see in your AFR's if VTEC wasnt enabling? It would be alot more rich wouldn't it? Also is there any easy way to display if it's engaging or not? Thanks guys.

You will have to look at the datalogs to see if it is engaging.
