K20Z1 VTEC kicking at 6200..when should be 5500

i-VTEC is always adjusting. Not like the old B and H series were its on or its not.
Read up on the i-VTEC system so you can understand how it works.

*adjusting during the revs.
I dont mean that one day its 5500 and the next its 6000.

I thought the only thing that continually adjusted was the intake camshaft angle. The traditional 'VTEC switch' to the high-lift cam lobes still happens at a set RPM at full throttle as far as I understand it.

yes, but Timmy did refer to iVTEC "always adjusting" - which includes the variable camshaft timing...

so whilst not being very clear or informative with his post, he was still close to the mark...

Too add to Tinks link.

i-VTEC is a little more complex than VTEC.
its VTEC + VTC

I understand how iVTEC works tink, and your article states what I was trying to say.

"The K20A2 head uses three cams per pair of inlet valves on both the exhaust and inlet. The low lift cams on this head are probably very similar to the high lift cams on the K20A3. The high lift cams engage at 5800 rpm and disengage at 5600 rpm."

It is a fixed RPM that the high lift cams engage, which is what the OP was referring to, not the VTC part of iVTEC (which is not really audibly discernible as it is a smooth change throughout the rpm range).
