Mine was 5100

Now its 4700 thanks to VAFC and tuning

So what is yours? And did you find out anything useful by lowering VTEC engagement, whether it be Hondata of VAFC

 

5200-4950

 

stock, there's no fun in lowering VTEC unless you have a really light flyhwheel and you want to stay in VTEC while you upshift. Otherwise, it's an awesome way to burn gas.

first off, if your falling out of vtec on the upshifts with a lightened flywheel, u need to learn to shift.

secondly, you can gain 25+ whp in the midrange just by lowering vtec alone, so I hardly call that insignificant.

And to the original poster, i usually set the vtec to about 4700-4800 on a mostly stock motor, that shows the most gains and smoothest power delievery on the dyno.

 

4000, but I'm blown

 

i have a vtec controller and the motor starts to open up @ 5000.
someone told me when you lower it past 5000 it doesnt idle right and ur gas mileage sux

Someone didn't know what they were talking about. Idle has nothing to do with vtec engagement.

 

Used to be 5250 RPM.
Got it tuned and it was set to 4800 RPM.
Got it tuned again with cams and it's at 5200 RPM.

But that's not surprising since you are now running different cams.

 

ditto. i have crower 2's and vtec is at 5200. if i set it lower, i feel a lag if engaging in 3rd/4th.

 

on @ 4900rpm
off @ 4500rpm

only activated over 20% tps, 150`F,

 

Anybody actually go below 4500 that isn't F/I ?

 

with stock cams, by 4500rpm, ur gonna lag. the lowest i have gain power on they dyno is 4700.

 

5800 rpm

 

it was set at 4700. then for some reason the VTEC engagment stoped working and i cant get it right again

i am going to rewire it all when i get back to the states. maybe something fucked up.

 

~4700 for the track
5200 for the street. no need to hit vtec during high(er) speed highway driving.

the Pirate

 

4500

 

4688

 

Just installed my vafc. I dropped it too 4800. It engages alot smoother and seems too pull alot harder on my butt dyno.Still needs tuned.

 

Quick question:

Is the JDM H22 VTEC engagement point different than the USDM H22?

 

dont know but i know my jdm ecu was 5000

 

4500 on my SH... actually gained about 10hp from the 4700 setting...

i tested from 3000 rpm to 6000 rpm and it was set to 4870 in the end
