Looking at some of the videos of people driving Hondas with VTEC engines, mine seems to be extremely 'subtle' about the VTEC kicking in, to the extent of me wondering if it's actually working or not - thus leading me to asking the following questions - At what revs should the VTEC kick in on my 2.0 Civic Type-S ? I can't seem to find a definite answer on this Is it supposed to be so subtle when it kicks in (assuming it is) ? If there WAS an issue and VTEC was not kicking in, would I be able to detect this with an error code that I could pick up with an OBD reader ? Does my foot have to be flat to get it to kick in, or do I just need to rev past a certain value ? Does VTEC work in every gear ?
