Gas Pedal Delay

DIGItonium · 12-21-2010, 04:19 PM

If this is a DBW issue, then it would be consistent from the start. The car is very responsive from the start after warming up the car. I can get the car rolling and floor it, and the car immediately revs up and overwhelms the tires.

After awhile, regardless of oil temps (even around 160-190 range), the car starts losing power below 3k band. Granted, torque is not as plentiful, but it feels artificially limited.

Anyhow, you don't need to floor it to feel the lack of power. You can give it 30-70% throttle while rolling in 1st or 2nd. The car initially revs up, but stalls around 2.5k before climbing past 3k and continuing regardless of throttle input. It feels like VDC cutting power. Now, while the car is "cutting power," I can literally go from 30% to 100% throttle in 1st and 2nd and it feels like I'm in the wrong gear.

Under this circumstance, and under casual acceleration, other cars are able to out accelerate me as the engine feels like it is struggling under 3k RPM even at 100% throttle and holding it down. Even with VDC off, the tires won't slip anymore from a roll.

I turn the car off and let it wait a few minutes, and the normal response comes back and I can start lighting up tires from a roll in 1st.

This is what I go through driving to and from work... not racing.

this pretty much sums up the experience of driving this car. this is constant for me and ive always chocked it up to DBW, because just about every DBW car i drive does the same thing, my moms TSX, my fiancees civic si, any of the newer cars i test drive at work... pretty much all of them. it makes it feel like a jerky take off. as far as the trouble as oil temps rise and loosing response, sure it happens to me, but not anything like some of these guys are describing.

so far we have decently conclusive evidence the following dont fix the problem being described:
1. oil coolers
2. reflashes/tunes
3. different engine oils
4. dealers
5. dealers
6. oh yeah... dealers

some have suggested the sprint booster thingy and swear by it... idk.

No problem here after technosquare.

Technosquare doesn't tweak VVEL, right? I'm assuming VVEL is still not really "cracked"?

I don't know if they cracked VVEL but I am very happy with their ECU.

THIS. Exactly. Feels like I'm a gear or 2 too high. And same here, day to day driving.
