Default Off-the-line acceleration?

I love my xA other than the off-the-line acceleration. I'll hit the gas, but it won't speed up right away. It's almost like it needs to ramp up for half a second or so before it actually starts moving. What can I do to improve this or make it peel rubber from a complete stop like my old K1500 pickup used to? (Note that I don't have a lot of extra money at the moment).

I enjoy rush hour, I just release the clutch at 3 grand and watch the cars in my rear view mirror get smaller as I reach 5 grand and shift to the next gear.

You just need to rev the engine up so the vvt kicks in. Otherwise you are pulling with less than 20 hp vs 90+.

Our cars aren't ment to be speed-freaks. Maybe you should have bought a earlier M3 used- 1995, for about the same money($15K) ?? Its a give/take between hp/torque and mpg .... take your pick.

Its not a bad little car for the price, fuel economy and manufacture. I get between 32 and 34 mpg just driving like the flow of traffic chirping tires at the stop lights than carefully watching it to get 40mpg.

I use to drive one of the worlds slowest production cars, a mercedes 240d. The only car slower than that was the grey imports o the 220d and 200d. It was a 4 thousand pound car with a 54hp diesel motor. At least I had the manual where as the slush box option took 3 minutes to go from 0-60 and it was recommended by the former owner to not be afraid to push the gas petal to the floor for acceleration or in some cases to just maintain the posted speed limit. I had to look over my shoulder coming onto the interstate to time/merge into trafic as the acceleration was noexistant.

I was under the impression that VTEC, what Honda guys use, kicks in at like 6500RPM while Toyota's VVT-i is continuous throughout the entire torque band.

I was of the opinion it works starting at 3000rpms. Sure its on the car like the air bags, but only used when you reach a certain rpms. I just know the power really builds fast in this engine, however outside that range you just dont have it.

Yah, I feel it all the time in my xA. When I first had my car before I started modding it, I can feel the max pulling action when I hit around 3000-3500 RPM and then it just kinda dies down.

I am guessing its like the ignition advance, so technically its there 24/7 but it works best at a certain rpm range.

According to one of the honda forums I was reading was that theirs kicks in around 4 grand, which can make your fuel economy suck as it burns more gas if you speed in your honda car. I kind of hate that since I do a lot of highway driving above the posted limit that I am pulling 4 grand. I am sure I just need the rpms not the full 105 or 109 hp the engine is making, but so far my fuel economy isnt suffering.

I read a lot of forums for real world fuel economy before buying my xa.

ok this has been discussed already lets not confuse vvt-i with vvtl-i or vtec with i-vtec.

vvti works all the time continusly the lack of pull your feeling at 3-4k rpm is the torque curve. variable vavle timing inteligence on these engines adjust the intake camshaft accordingly to run the enigne at the best possible range programmed to the computer for fuel mileage.

vtec is works like this honda engines usally run on a 2 valve system once they hit a certain rpm then all 4 valves in the cylinder are used. obviously allowing to breathe better but lowers your mpg since now it needs to add more fuel to the ratio. this essentially gives you a kick in power feel.
