did you really have to make more than one post about your stupid question?

vtec point should be set to 6500 RPM's and redline should be set to 12,000 RPM's

don't misinform the poor guy

vtec should be set at idle for max performance and the revlimit at 5000rpm, because most engines go kaboom if the vtec powerband is extended for more then 4000rpm.

OP don't be fooled by what other people try to trick you to do

I do not know much.
If you do not know Do not point wrong.
other topics of the forum reviewed the idle AFR: 14.7 I have read that.
Thank you anyway.

VTEC crossover 5600 - 5900 rpm (depends on where your engine performs best, find the rpm that has smoothest engagement point with no hesitation or big jump)
Rev limit - 8100 rpm
Idle AFR - 14.7 - 15.5
Wide open throttle AFR - 12.75 - 13.5 (also depends on where your engine performs best)

A dyno or good street tune with datalog will be a better way to find where your engine performs at it's best. For both AFR and RPM crossover points.

Thanks for the information you provide.
VTEC point 5900 using current setting.
afr at idle you say you want to set mine up to the poor.
Can you look at the comments in my hand the current output of the dyno?

If poor = leaner, than yes, that is what I am saying. A lean idle is OK, your engine doesn't need 13:1 AFR at idle. It really only needs enough to keep it running. While at the same time keeping it from detonating (going too lean)

If your engine is making power above 8000rpm you would want set your rev limit higher. However, I didn't see anywhere in your build that you have done any work to the valve train or block. You might want it to be around the 8500 rpm range with a stock valve train and rod bolts.

From what I can see your dyno looks pretty smooth. Have you tried different changing the AFR's and timing to see if it will make any difference?

I have a great idea! How about you pick up a tuning book and read it. Or at least search.

Sorry if I come off being a dick...but seriously
