Semi auto euro is faster. ;) (experimenting)

Ok, I will rephrase.

If you are smooth at gear changes, the sensation of slowing down will be greatly reduced by smooth engagement and acceleration in next gear.

Easy clutch take ups mean smooth gear changes.
Don't be harsh on the clutch (take-up's).
Nothing to do with how quickly you step on clutch.

I find 1st gear is really touchy when driving sedately though, because of the instant responce of the drive by wire throttle. The other gears I find are smoother due to momentum and they have some weight to pull.

Practice at lower rpm's (~2500rpm) changing smoothly. It will make it heaps easy because of the lack of response at low rpm's.

The undesired effect comes when at 4000rpm I am in the process of pressing DOWN the clutch. I am still in 1st gear and haven't changed to 2nd yet.
At 2500rpm, I can shift 1-2 without the passengers excessively bobbing forward. Of course, shifting at 2500rpm means that Camry is ahead of me already. :)

Oh don't forget you'll be riding the clutch if you let it out too slowly, which aint too good for it.

They don't notice? Hmm, at 2500rpm shifts, I do it fast and smooth, I can see them but they don't complain. It's only when doing 1/2 throttle up to 4000rpm and then pressing the clutch down is when they notice it. :mad:

There is still that point in time where you press the clutch and have yet to get into 2nd and release the clutch. This is my problem. Because the acceleration in 1st up to 4000rpm was strong, the moment I press the clutch, the passengers go forwards.
My problem in not with the take up of the clutch pedal. It is with the change in acceleration at 1/2 throttle 4000rpm when I press the pedal DOWN (clutch disengagement) when doing the 1-2 shift.
Like I said previously, if I shift from 1st to 2nd at 2500-3000rpm without hard acceleration, it is smooth as silk.

The only way I have tried that can reduce this problem is accelerate 1/2 throttle up to 3500rpm so I have hard acceleration, then ease off the throttle a tiny bit for the 3500-4000rpm range and then shift so that the change in acceleration when I press the clutch is not as drastic.

Righto, I don't think there is any solution except tell your friends to shut up or walk :p

Either that or just drive around in second.

Hehehehe :D I'll just give them a taste of 7000rpm, that will keep them quiet.

This whole thread has just confused me!!

you can try to shift after 4000rpm, given that the engine develops its peak torque at 4500rpm. which mean, you can use full throttle till 4000rpm, then reduce the throttle a bit and upshift.

but like what the other forumers said, the pax will still get a sensation of decceleration.

Sorry for hijacking your thread, Faiz. My opinion is that using semi-auto is faster than "D" mode because you can use the higher revs more.

i will be confirming that soon arrong ;) i will state my results then.

and when did higher revs mean faster??

you just want to get high enough revs so that when you go up a gear you're still using as much of the peak of the powerband as possible (i.e. maximising the area under the power/rpm curve)

That is why one should shift gear past the "peak power" RPM - because you can get more area. Not because it gives you more "power" at a static RPM but because when you change gear between two RPM points which gains the overall best power at the rpms that u will use

I have never seen low revs mean faster, especially in a honda.
Euro goes best between 6k and rev limiter, so higher revs mean faster :p
