was the car warmed up when you were trying? how is the oil level?
actually YES it should. the ecu wont let VTEC kick in unless your car is up to operating temperature (there are other things also but this is the one in your case). its to save you from killing your engine when you do stupid stuff like try to hit VTEC when your engine is coldAuz said:the oil is good, the car was not wrmed up, but this never happend b4.........and it shouldn't
but this never happend b4, and the feel is like somthing is holding the car.....it's like when you are trying to run and someone is grabing you....it feels as if you are draging somthing.....4bidden said:

i can see that happening, but why would it happend now, and not before.....it could be the oil, but i'm thinking it's somthing else....i just called them and they didn't look at it yet...it's been over 2 hrs........i need all posible things that could make this happendMike Natoli said:I had that problem and Honda told me that it was because the oil pressure wasn't high enough, and that I should wait for it to warm up so the pressure could get up where it needs to be.
Totally agreed m8Leprechaun said:Who cares if it is not pulling hard when the engine is cold? Don't push your car to the limits without it being warmed up...do you want to fuck up your engine?
Oil viscosity is one issue when the temperature is still cold in the engine, but it isn't the main issue. Oil is captured at the filter (via the anti-drainback valve) so it is very close to the top of the engine on startup. Oil will be properly circulating within 30 sec of startup, but you are right - it won't be optimal temperature.Weenie said:seriously. are you crazy? unless your temp guage reads at least halfway (or whatever it holds steady at during normal driving) then you shouldnt shift past 3500 at the highest. if you keep trying to hit vtec while the engine is cold you can say goodbye to your engine. thats one of the worst things you can possibly do to your engine.
think about it...the oil has to heat up to be thin...when its thick it does not protect the engine parts well at all. if you spin the engine that high while the oil is cold your going to be in trouble.
Yeah Exactly....Id even say 4500 is taking it too far. Id take it to about 3000 the 2.2 has enough torque to easily get around under that. The preludes oil-pressure also gets max pressure at 3000. I forget as well but a system also kicks in there....Im pretty sure its like a 3rd stage of vtec....or the 2nd stage and its a stage that readies for VTEC and i think the timing changes up some....or something. I forget what exactly what it does but you can hear something as well as notice the power comes on strong after that.BaronVonFlop said:
I would say to stay under 4500 (I don't know why you would need to go that high anyhow) until it is at operating temp. Take it easy and slowly build up to climax (hehe). You want your car to last!

One thing I like about my 4g prelude digital dash is that you know right away when it will let you hit vtec (the first bar on the temp gauge flicks up one bar)....other than that your limited to about 5500 rpm....if you try to get past itll sound real odd and youll stay on the low-end VTEC cam profile....just struggling.....in reality this is the limit of the low-end cam and then finally youll tap a revlimiter.
Its funny too , ive sat on my little cold rev-limiter , waiting at 5500 or so almost half throttle and its funny to hear it not revving out and hitting a limiter , its like bowbbowbowbowbowbow.
Then the bar goes up one bar on the temp gauge and ding....you hear the pin click. VRBAAAAAAAHHHHHHHHHHHHHHHHHHHHHHHHHHHH , and im off.
I dont suggest doing that , but i wanted to show my friend one time...since he didnt believe me.
-- Also HIGH-CAM VTEC Engagement all depends on oil-pressure, if your too low on oil it wont engage.....
I think only prelude's have this.
