I noticed this when I was pulling out of school. The engine was still cold and I took it up to around 4k and shifted for 1st-4th. In each gear I could feel a good bit of extra kick when I hit 3750, when the secondary ports open. I felt this in each gear but less pronounced in each successive gear. When it warms up though I don't feel it. Any idea why this happens or am I the only one noticing this?

 

it's the vtec kicking in...

 

vtec pwns yo!

 

Arg... Seriously...

 

cold tranny fluid = not as viscus ?

 

the car is running on open loop until it warms up. could be that your open loop is leaner than your closed loop depending on your LTFT. also colder temps generally equals more power than warmer- and the intake air is going to be warmer from passing thru the intake tract after the car is warmer.

if you had a scanalyser you could track you intake air temps from start-up to warmed-up

 

thanks Zoom. THat makes sense in a way.

 

Zoom44 knows his stuff. Its not good on your Car to drive it when its cold. Let her warm up. + you get better gas per gallon too.
My Friend just got a TL, When its cold it wont let you rev it pass 3,K RPM'S.
