changing idle flunctuation

Its easy to let the idle revs either hold the car stationary or pull off!


Well it is with a 2.5 V6 Diesel anyway :)

For what its worth, the 20vt VAG engine can easily pull away from the steepest of hills on the bite point, it just keeps raising revs until it goes.

No surprise to me. It's amazing what a car can do at idle if it's not badly underpowered or at too low idle.

NO. Not move-the-car... just to hold the car in place long enough to get to the gas pedal.. lol

As some else has already said, whats wrong with using the handbrake?

1) Handbrake on (should be on anyway)
2) Stick it in first.
3) Rev a bit.
4) Drop the handbrake, while the clutch comes up and the accelerator goes down.
5) Produce satisfying wheelspin, followed by movement.

again yes I know about hand-brake on extreme hills.

I was taught to use handbrake on any incline, to stop any rollback, and so you're not chewing your clutch.

Anyway, thanks everyone :)

What?!

What happened to using the handbrake on a hill, then finding the biting point WITH a bit throttle and then pulling off that way? They dont teach you to get the biting point without the throttle...

it's worked on all other manuals I driven just fine. you'll even find that technique in a driving manual

You are attempting to stop the car moving backwards by letting the clutch slip, it's not a good idea, I bet the author of said driving manual wasn't paying for the clutches!
 
I wasn't expecting debate nor the jokes about my clutch control (which is just fine... arg).

Anyway, I guess in the UK people only use hand brake on any hill. Good enough.

But those who don't have really underpowered cars... just try it before you knock it. It's pretty neat and it doesn't eat the clutch any more than moving off, probably less if you don't hold position for too long. Go to a reasonable incline and try it. With foot on brake, raise clutch until you feel a slight shudder... don't raise clutch too much. Then release brake ... if the hill is not excessive, the car will hold. Less cumbersome than using hand brake every time. I didn't make this up, it's what I and many others have been taught.

Cheers :)
 
Fair enough if you've got a huge engine-d car or a diesel, but you've got a 2.0 Mazda.

Most people don't actually use the handbrake on a hill-start anyway - off the brake and straight onto throttle/clutch and the biting point will get you underway quite happily.

And TBH if you went to a garage about this I think you'd get a few smirks. ;)

Fixed and please explain how it will wear the clutch less?

it has no problem doing it when the rpm's haven't dropped by the 300 rpm amount. And other non-diesel cars I've driven have also done it just fine.

I know that. I do that too.

Thanks for the warning, but I've never heard of this technique being a no-no. Different strokes in the UK.
 
BTW, I think some people mistunderstood "cooling fan" for the A/C. I meant the cooling fan on the rad.

Also BTW, the level that the idle rpm drops to after the fan has been runnung is lower than average for the car.
 
I really don't see the advantage of this technique. How can it be any quicker than using the handbrake, throttle and clutch simultaneously? Even being lazy and not using the handbrake it has to be a pretty steep hill for you to roll back any significant distance just by jumping off the (foot) brake onto the throttle and letting the clutch out - although isn't the smoothest of techniques.

In which part of the world do they teach this crazy method?!? :confused: ;)
 
get a Discovery if you want to do this :p probably totally different on a car but a lot of bikes just have a dial that you turn to upp the idle revs :p
 
Well I fail to understand how doing this wears the clutch more than regular moving off or for that matter doing a hill start with the quick-footed method. If you've never done it yourself, you're probably imagining something brutal... it's very quiet, uneventful and smooth when you do it.

Anyway thanks. Maybe the Mazda 6 just isn't a good car for doing that with. Oh well. I'll just get out of the habit if the rpm drops can't be "dialed-out" of the system.

Tried it on the way to work this morning.....and bugger me....it actually works, as long as I bring up the clutch slowly. :o

Just found a steep sloped side-street, stopped at the bottom, stuck the car in first and lifted slowly, it make a little grumble when the clutch was 1/2 way up, but then went on to creep all the way up to the top, without me touching the accellerator pedal. Slowly admittedly, but it did do it.

Yeah i know, i do it when i have to and its really no big deal! Can't feel it putting any undue strain on the car.
 
Isn't the OP just talking about effectively "holding the car on the clutch" like when you are at a junction on a hill and you are waiting for a car to pass before pulling out?

Yes, also known as slipping the clutch :p

As volospian said, it's only to hold the car while you move your right foot from the brake to the gas. Once you're on the gas it'll feel a little different from your usual moving off since your clutch is already part way up... you might chug a little the first time you try it.

No, becuase he isn't using any throttle before he releases the clutch completely.
