A buddy of mine has a smogging coming up and was thinking that if he disabled his VTEC with a controller (set it to come on at like 12k RPM) he would do better on smog. Im not up to date on "smog technology" so I have no idea if his idea is sound or not -- > Would something like this work, if not what the heck should he do?

 

I doubt the testing station would take his engine up to 12k rpm.

 

i think that was his point, so the vtec won't engaged. i don't think vtec matters for smog but i could be wrong.

 

VTEC doesn't matter for smog. On a normal smog test they shouldn't reach the VTEC engagement anyways.

 

I don't think VTEC matters. They usually run it around 2400 rpms or so....depends. I'm not uptodate on my smog stuff either

 

smog runs, 2nd gear - 15mph@ 1500-2000rpms, then 3rd gear - 25mphs @1500-2000rpms.

So no its not needed to disengage vtec.

 

You may want to lean out your fuel alittle. That may do it depending on setup.

 

leaning it out will not be any better. It produces more NOx(most concerned pollution), when their is more air and when the engine is hotter. The leaner you run the hotter your engine gets. You want it 50/50
