If it's SOHC VTEC, then I would deem it relevant to the the Fit's 1.5L VTEC.

I believe the VTEC for the Fit is different than the traditional VTEC used in other Honda engines.... here is a blurb I picked up...

The VTEC mechanism on the L15A VTEC is that of a 1-valve/2-valve system for the intake side only. The exhaust side always functions as a 2-valve system. So the L15A VTEC is a 12valve/16valve system. Here again, misunderstandings and prejudice abounds. Firstly because the original B16A engine that pioneered VTEC was a 3 rocker/cam-lobe design, while the first 12valve/16valve VTEC implementation was on the VTEC-E D15B engine, many have since labelled the 12v/16v VTEC mechanism as the 'economy VTEC' version while reserving the 3-rocker arm mechanism as the 'true power' version.

For the 1.5L VTEC, the exhaust always has two valves per cylinder. The intake side has only one valve per cylinder until around 3.5k rpm (VTEC engagement) when the secondary intake valves open.
