Post subject:  Hand Throttle/Fast Idle
I have just set up a hand throttle in my sierra. its a choke unit of an old subara wagon.
Pull the knob to set your rpm then flick a switch to lock it.
There is an electro-magnetic clamp inside the unit which locks the cable in place, flick the switch off and the throttle returns to idle.

Im pretty happy with it although its pretty hard to pull the knob so i just have to use my right foot to assist.

Has anyone else got something similar or any other hand throttle set up?

I havnt fitted a switch yet but u can see where it will go.
Image

Whats hiding behind the dash, this box contains the electromagnetic clamp. there is also a light trigger. so i could rig a dash light.
Image

The cable is a little long so i ran it along the dash rail then back to the right hand side of the dash and down to the pedal.

this is wear the cable attaches.

Image
Ensure to leave slack at idle so the knob does not affect normal idle speed.

This is full throttle.
Image

i just took the accelerator cable off slid the choke cable in between the two plates and put the accel cable back on.

I've got gears so am on the upper end of the rev range usually.

I have seen a hand throttle setup that was an old Victa chrome throttle lever and cable mounted on the gearstick like a truck range/splitter switch.

I mainly got it so i set a fast idle for my air comp. but it will help with warm ups on cold mornings and it will mean i dont get throttle bobble offroad.
to remove any confusion i can set it anywhere from idle to red line

I ran a cable to the idle up part of carby.
Used the 1.o litre choke cable already fitted,
as I'd upgraded to 1.3 donk.

i've been meaning to hook one up in my Vitara for the last 6 years.... might actually get around to it soon, will be using the guts from a MTB grip shifter as the gear knob on either the transfer or gear stick rather than having a dicky odd looking lever in a late model interior.

EFI could be electonically switched to idle up

That would be sweet like the throttles on Cat 1 tanker pumps.
they have a linear actuator but the throttle is a n rtc toggle switch each flick is 100rpm.

On a Vit, I think headlights, air con and temp all cause idle up,
so it could be done.
On my Sierra, I needed it for stall prevention, hill starts and stuff,
because of a dicky clutch leg.
I not so worried on me Vit as its auto.
But if need arises, will go switched hi idle, rather than full hand throttle

Vit has PS idle up too.

Does Vit idle up work off a load sensor? my xtrail has load sensitive idle, so its pretty dificult to stall unless ur trying, you can almost drive with out using the right pedal at all :lol:

My G16B has an anti stall idle up but I have absolutely no idea where it is or how it works. Never bothered to find out cause it still works.

there would be limitations though with the throttle body being completley closed? i suspect a mechanical/magnetic solution would be better.

Is there something avail where you can just set it with your foot and flick a switch to activate an electromagnet style clamp or similar? (just spitballing here)

Thats almost exactly what i have rigged up Scales. though it uses a knob. but pulling the knob does actually depress the pedal.

You could always go to the wreckers and get an idle up cable/knob thingo out of a GQ for a few dollars. Not a high demand item so they'd be dirt cheap.
Would look like a factory install too.
