Throttle not responsive. Normal or not?

[Babs]

Hi guys,


What I have noticed with the new MY12 Deefer is when I accelerate the throttle does not immediately respond, I have to press at least 1/4 of the way before it responds, is this normal?

Taking off on a hill especially with a trailer is scary, as I ride the clutch because there is such a long pause before the revs come up. The Hilux I had as soon as you touched the accelerator it would respond. I'm a little confused as to wether this is normal and I just have to adapt my driving style.

Also wondering if this might be linked with the high fuel consumption I have mentioned in another thread?

Any thoughts would be greatly appreciated. Cheers.

Yep, it's completely normal Babs. Takes quite some getting used to. It's actually a "feature" that was designed in for the fly by wire throttle. I suspect only the engineer that designed it knows and/or appreciates it, but that's all part of Puma ownership. It doesn't have to make sense does it??:D
So, no, it won't have anything to do with your poor fuel economy.:(

you need to change your driving technique, try this

put it in first ease up on the clutch and release the handbrake finish releasing the clutch and then apply the accellerator.

you dont need to use the accelerator to move off in a diesel if its set up correctly and geared appropriately.

Blknight,

Sounds good, but what if I'm towing and taking off on a hill, this scenario happened this week, scared the crap out me, had to ride the clutch and rev the puma out before I could fully release it, and that long pause before the power comes is enough to either stall or roll back.

But if its normal your right I'll have to adjust my driving style, and use the handbrake. It all takes getting used to. I think I've gotten soft since last owning the Hilux it was the first auto I ever bought (well for me that is) and previously to that I had the last of the Patrol GU 4.2 TD and in my younger days had a couple of Troopies.

Ahh it's good to get back to basics :)

Gotta' say that I've never noticed this in my Puma - maybe I just adapted without realising it?

If mine wasn't 400km away ATM I'd take it for a quick spin to check...

I know its a different motor, but using the method Blknight.aus suggests I can pull away on an incline in my TD5 towing a 3.2 ton caravan ( and do). Give it a try, easy on the clutch and dont touch the throttle until it is right out.

What I've noticed with my Deefer vs our Patrol and other Japanese diesels is that the throttle response is 'soft' so the engine doesn't surge with the bouncing of off road driving. ie. you don't have to rely on a hand throttle off road.

[uninformed]

yes, as rick says, its a long travel throttle for a reason. I believe that its even in the TDi manual somewhere....

hand throttles are only for stationary engines IMO

I have found that down-changes from 4th to 3rd work very smoothly with a little "blip" of the throttle. Getting the blip just right is a bit of a trick with that weird throttle response but can be mastered. When you master that, you start to realise it'd be great if the Landy engineers had made the throttle and brake pedals the same height so you can "heal n toe" for down-changes ... but they weren't engineering an F1 or WRC car. (They "engineered" the Defender???:p)

Throttle pedal mod (in a Tdi) for heel and toeing ;)

Ile agree with that I had a gq diesel and in low box it was very touchy and if it started to bounce around on rough tracks it would be very hard to control the throttle the landy no worrys even on the roughest tracks and when spotlighting I know I won't lose shooters off the back from bad throttle control

It was impossible on the leaf sprung GQ ute we had on the farm.
The only way to drive in the rough stuff was the hand throttle, if you tried to use your foot the bounce and subsequent surge would just start a loop of bigger bounce/bigger surge.

SWMBO's coiler GU wasn't much better, luckily it hasn't been off road since we left the farm years and tears ago, just does road and paddock duty on our little 8.5 acres so it doesn't matter.

I find that just getting it moving on a hill start only requires you to let the clutch out, pausing at the take up point so that the computer takes over, then releasing it fully...no accelerator required. The anti-stall feature promoted for low range also works in high range, adjusting to 900 rpm and balancig the fuel to suit the load...makes life easy.

Puma 2012 110 Wagon - Just racked up 10,000kms, 4 days on Fraser Island, almost every sunday she is in Low Range climbing some dirt hills....

The throttle lag is my only complaint with the 'fender! You basically need to engage the throttle a full second before you actually need it. The amount you have to depress the pedal before it lifts the revs even slightly is really annoying. The first 15-20% of throttle does little to nothing. I must say I have now got used to the throttle, but I still dont like it.

Does anyone know if the remaps such as the one offered by IRB Developments improve this erm, "characteristic"?

Blknight,

Took your advise on this one, its been a lot more easier to drive since. You really have to have a lot of trust in that anti stall though.
