That would probably be a good idea since you are too stubborn to convert to manual even though you are adding power and know Honda auto trannies suck.

I think the performance you think you are gaining when the engine is cold is all psychosomatic. Leave it how it is.

 

are you guys saying that your vehicle runs better in a) cooler weather? b) under normal operating temp? there is a big diffrence in both. all cars run better with colder air since it is denser which means you can pack more air in the same amount of space. more air equals more fuel (o2 compensates) hence the car feels quicker. all cars feel quicker this way...or should i say most cars. (lol das shmoo)

if you are saying the other way...under operating temp......first off....vtec shoudlnt work so the car should feel slower. if you have a vtec controller then this sint the problem. but maybe the motor is cold meaning your intake is taking in the colder air (see above) when your car warms up...then your intake is now surrounded by hot explosive air.

if you wnat your motor cold....really cold......drill a small hole through your thermostat. you wont have heat since heat works off of heat from your motor. also you could try to cool down under hood temps by rasing the rear end of your hood with spacers or washers. a cheap mans way of a "hood vent"

 

Not true.

My car runs like a dog until it gets up to normal operating temperature.

 

I know my car accelerates quicker when below Normal Operating temperature, I burn rubber on Full Throttle from Idle, but when my car warms up it doesn't respond as fast in the lower RPMs 3,000 and below and VTEC does kick in when below Normal Operating temperature, I know because the red light flashes on the VAFC2 to signal the high cam crossover, it just shifts at a slightly earlier RPM.

What would work better? open or close loop tuning using the vafc2 and wideband? or it doesn't make a difference?

cool weather and below operating temperature does my car real good. could it be a valve clearance issue?

 

could be your cold tires

 

exactly...if your measure of speed is spinning tires. cold tires dont get traction

also cold pavement has the same effect....as in winter wise. so you might have a higher top speed in winter but your 60 foot wil suck as in dragstrip runs.

and das shmoo.....i meant all na cars...you must be running a turbo setup? sorry for not clarifying that. and i take back that comment......most cars have a better torque response when cold...is that better?

 

I was thinking it could be the tires being cold too, maybe they spin and when they hook up I'm feeling the nice part of the torque curve when it reaches the ground.

I done something really bad... I accidently broke the top of my B&M adjustable fuel pressure regulator tonight, and I'm forced to drive the car with 42PSI constant fuel pressure with lol... it was originally back on 34 PSI before I tried adjusting it.

I leaned out my VAFC2 to be on the safe side, tomorrow I'll replace it.
