Outer Limits 4x4 Board

Just wondering if any one has come across an electronic speed sensor which will fit up to a manual 1.3 W.T transfer and drive a jimny cluster? Ie is there a slim chance that the jimny one will fit in the sierra case?

Basically the issue is i have a jimny auto, and efi motor going into an LJ81 and would like to use the jimny cluster but dont want to use the jimny transfer.

no it won't fit in the case but you can use it on the rear drive flange. you have to notch the flange with the same amount of teeth as the speedo gear in the jimny.

Tanshi,

You need to do the same VSS install that people do with a Vitara Auto.

Basically you get a part from an EFI vitara instument cluster and put it into a sierra cluster.

Do a search on VSS - we have discussed it a few times.

I'm not sure how it will work with an LJ Cluster though.

Cheers,
Greg

rick from BBM used to have a kit to do this externally on the transfers. It mounts where the handbrake used to bolt up and uses the OEM sensor

hmm BBM might be worth a look.

Greg, im gonna try and use the jimny cluster in the LJ with a sierra transfer so i think it will be the other way to the one your thinking but thanks for the input any ways

D and G tuning in europe look like they do a kit but it is really expencive and involves changing the rear flange for a non standard one any one else done this or similar and have any input?

on second thought will i need to do the VSS thing. i was only considering how to make the jimny cluster work woth the sierra transfer but will still need to do some thing about the vss for fuel economys sake?

I used a machinery toothed timing belt gear (a #26L075F from any good bearing, chain and sprocket supplier) when putting a SJ410K 3.05:1 box into my Jimny and had it machined to fit the rear output flange (basically where the hand brake was mounted).

However, about 20 minutes ago I checked the latest posts on a Swedish Jimny board and found a post linking to this page from the motherland with pictures like this...


The trick is to increase the number of teeth to correct for bigger rubber.

Denby thats a impresive bit of gear..

does any one know where u can buy a jimny vss??? mate needs one..

Yea... I wish I saw this before I got mine made...
Mine is rough in comparison... but it works and the speedo is now correct

Any pics of yours?

I need to buy/make something like this, mines been sitting on the back burner for a few months.

The 26L075 toothed belt gear as purchased
I used a 26 tooth gear to replace the 25 tooth original gear to correct my speedo. The site I linked to in a earlier post gives suggested tooth numbers to correct for bigger tyres.


After machining (the teeth were cut a little deeper BUT this may not be required to trigger the sensor as others are using a transfer gear left over from a Rocklobster conversion)


Hand pressed onto the rear flange (a Samurai rear or SJ413 front) with a little Loctite to stop it falling off or turning


Bracket to hold the original Jimny sensor


Sensor with block of hardwood to protect it from debris.
NOTE: This wood was trimmed after this photo was taken to allow for the driveshaft bolts


Mounted in place

Denby thats fantastic, ive been trying to find a pole wheel suitable for this use for a while, looks like you found one thats optimal.

I would have liked to use one that was smaller in diameter but then the depth of the tooth became quite shallow... and will a shallow tooth still trigger the sensor???
The poms seem to have solved that using a transfer box gear but I still have doubts about the accuracy of the sensor with a shallow toothed gear. British site is here

A google search shows the 26L075 listed on the Challenge Power Transmissions web site in Scoresby Victoria.

But this will only work if you use a jimny ECU and Speedo or what?
The mod is intended for jimnys replacing the original transfer with the Sammy transfer gearbox.

Some of us is using baleno enginges and the baleno ECU is used to getting a square pulse signal from the electronic speedo wich gets a sinus signal from the baleno gearbox. (Manual trans.) To calculate what frequency one should send to the ECU at any given speed you would have to know the gear ratios from the driveshaft and to the baleno gear box VSS.. sounds like a pain to me to figure out
The speedo sends half the freq. of the input to the ECU btw acc. to FSM..

You are correct Yakuza, what I have described is for fitting a SJ / Sami transfer into a Jimny (and probably the Coily Sami as well as I think they use a similar transfer box to the Jimny and probably the same speedo sensor).

With the Baleno engine (while still in a Baleno) how does it get a speed signal, is there something attached to the gearbox, differential or an axle which triggers a sensor of some type?

If so, why cant the sensor that matches the Baleno ECU be mounted in a similar fashion to what I have done when putting it into a Sami or even Vitara?

That way the Baleno ECU would be getting the correct signal as it is coming from a Baleno sensor... it is just being physically triggered from a slightly different point in the drivetrain.
The you don't have to worry about the frequency or that messy electronic stuff, just use the matching bits and manufacture a trigger to suit.

To calculate the correct number of teeth required on the trigger gear just work out the circumference of the Baleno tyre and divide it by the number of teeth on the Baleno trigger to get the distance travelled per pulse. Then divide that distance into the circumference of your Sami or Vitara tyre.
I would guess (and it is a wild guess) you will get a number between 20 and 50 which is how many teeth you will require.

Best of luck.

NOTE: The value of the advise given above is proportional to the amount paid for it.

ok so the question remains, Baleno engine, Jimny auto. Is the Vitara VSS greg mentioned. The Jimny one which Denby awesomely put together a guide for. Or some thing completely different the best option? I would have liked to use the jimny cluster but if i cant then i wont.

there may be a better option, but mine is definately working.

you could always be tricky by running both - have the jimny speedo widget in place so you can use the jimny dash... then behind the dash tucked away out of sight you could have the sierra speedo with vitara vss.

that said - the jimny speedo widget would make the vitara vss superflous anyway.

.

nope coilies are cable driven same as the leaf sprung ones. you can actually just use the original cable and everything and pow your done.

tanshi - i just thought of something else...

You can't put a jimny dash in an LJ - it would look terrible!

vitara dash in an LJ....

See Greg's comment above.

The only dash that should be in an LJ is an LJ dash IMHO.

Each to their own.

Steve.

pppffftttt....in a perfect world maybe.

In a perfect world ljs would have come out with 1.6 efi, 4 speed auto etc. i get your points tho however im not staying true to the original vehicle in any way shape or form so... I have measured up the WT sierra dash and it will goin and look shmick but then i like the sierra dash and alot don't. The jimny cluster looks like it will be easy enough to fit into the sierra dash using the sierra perspex front and just fitting the cluster behind it.

So the Vitara VSS will send the correct signals to the jimny auto?

tanshi wrote: So the Vitara VSS will send the correct signals to the jimny auto?

no...

kidding.

yes - it will work. that's the setup i have and it works a treat.

then sierra/vitara cluster it is.

According to the pictures in the manual i have, the Baleno VSS sensor that mounts in the gearbox looks similar to what Holdens run in the turbo 700 trans, ie gear driven.
If i used a sensor say out of a Vitara that is not gear driven but senses a pole wheel, will that still work for a Baleno dash? I have just grafted the Baleno speedo and tacho into my Sierra Cluster, is sweet and looks almost stock, would hate for the good work to be wasted, as the gear driven sensor would be way too difficult to implement.
Im thinkin i might use the Vit sensor with a similar setup as pictured before, then just use the Jaycar speedo correction kit to tune the speedo instead of trying to calculate the ratios.

PJ Remember!

* I have the Baleno speedo and Tacho Faces.
* Vitara Vss speedo internals. Including the Kms/Trip meter etc.
* Baleno Tacho Internals.
* Sierra Arrows

With the 33's(32) and 3.7 diffs, its almost perfect reading for the speedo! (Tests have been checked via driving beside a 07 civic with a big digital dash):lol:



All the suzuki "cable" speedo's i have seen use the same principle. "734rev" Is this correct?? I Think i remember seeing this on Swifts, Vits, Sierras driven speedo's

Sorry i meant Jimny sensor not Vitara VSS sensor (was soused when i typed that). Can i use a Jimny VSS sensor with a Baleno speedo cluster?

This is what the sine wave looks like for the Baleno VSS sensor. Being that it has two wires, its not a Hall sensor producing a square wave i dont think, so to produce a signal it requires the notched wheels to be moving constantly past the sensor. I need to know, is the Jimny sensor a Hall sensor or not? Does it have two wires or three? If it only has two wires i think it should be compatible.

Dammit just looked it up, looks like the Jimny VSS sensor is a Hall sensor not a VR like the Baleno, so they are incompatible.
Im thinkin now that i may be able to use the Baleno crank position sensor as its a VR sensor so i should be able to use it as a VSS sensor for Baleno dash.
