H22 Vtec... is setting the VTEC point at 4500 too low...

 

do it at 4800

 

Thas a lot of gas to pump I think from 4500 all the way 2 redline, jus do a trial error, and time it within a certain distance

 

with stock inturnals I'd say somewhere between 4400 and 4800. but a dyno is the best place to find out what's good for your car

 

do it on a dyno and you will know which is the best point

 

If your car is stock, leave it at the stock engagement point. Honda knew what they were doing when they set it where it is. Dyno it test some settings if you want it earlier but if your stock, leave it stock. just my opinion...

Its there for a reason, that and the fact that no normal person wants to be in vtec in 5th gear when there crusing at higher speeds.

 

What is (excuse my language) ******* the stock vtec point, i keep getting different answers.

 

They tuned my car's vtec point at 4200! it worked out well.

 

5200RPM stock VTEC engagement point for 5th gen Preludes to the best of my knowledge.

 

5200 is correct.

You win a 1985 Mustang! Tan color.

 

So where agreed at 5200. Is this on both gen's.

no only on 5th gens.

4th gen is 4900

 

Realy, thanks that helps alot prelittlelude, considering i have a 4th gen lol.

 

its definitely 4900 on 4th gen although it looks like 5200 or somthin on the tach. I'm not as sure about 5th gens but I thought they were the same.

 

yes there is approx 300rpm difference in the stock tach and actual RPM due to the mechanical guage. as speeds increase so does the inaccuracy of the mechanical guage.

 

leave it at stock, they knew what they were doing.

 

I belive all h22's are at 5250, aka 4th and 5th gens engage in the same place.

 

true story^^^

 

well you believe wrong. 4900!!!! this should be posted somewhere viewable by everyone cuz I hate saying this **** 20 times b4 people quit throwing bs out there.

 

4900 is 4th gens andi really have no experience with 5th gens so i couldnt tell you. although in 4th gens it looks like 5200 because of the inaccuaracy of the manual guage.

Vtec is engaged at 4938 and disengaged at 4750 in a high load situation,
and it is engaged at 6313 and disengaged at 6188 in a low load situation. In a stock P13 ecu..I know this for a fact..From looking at the code..

The best point to set your vtec crossover is were your power curves cross on a duno. If you don't know then leave it stock..
