1st, you will need to give us tyre size man. It'll be like 225/35/20 or something.

2nd, If the transmission is anything like the 3rd gen 5 speed autos (which I believe it is) it should hold 8 liters. Engine should hold around 4.7 liters.

i think the engine holds 4.3 lts with filter and transmission is 8.4 liters

this is a handy site just put your car make model in and gives lube guide

hi man they are 225/35/20 sorry guys wont be putting up pic's till the car is slammed

For the tyres then, assuming your SX came with the optional 17x7 alloys, the standard tyres were 215/55/17.

Now you have 225/35/20.

Stock tyre diameter is 668.3mm, 20's is 665.5mm meaning when your speedo reads 100km/h, you're actually travelling 99.6km/h, so pretty much bang on how it was before.

im running 235/35 20 and haven't had an issue with the speedo being out at all really maybe 2 k's according to the nav man, slammed on 20's this i gotta see man im on super lows and still look like a pajero lol.

If you have 8.5" rims put a 245/35/20 on & the speedo will read about 2% fast. With the 225's it will read about 5% fast.

The speedo reads fast from the factory with stock tyres.

thanks for that link jamie64

yep mine did come with the 17x7 215/55/17 and now i have 20 x 8.5 225/35/20.
good to hear just don't want to get done for speeding etc thanks for your help

slammed on 20's this i gotta see man im on super lows and still look like a pajero
i would never trust the nav man to much delay etc i'm still getting the super lows nothing different to you lol
from what pic's i have seen still much better then stock no where near pajero haha

5% faster? the other fellow member said it's almost on the money? i'm guessing i'm going to get a lot of different answers then :)

That's because the stock speedo reads about 5% fast, if you want to correct it go the 245's.

I get almost the same calculations as Disciple using this website... http://www.rimsntires.com/rt_specs.jsp
... so I agree with Disciple, "...pretty much bang on how it was before."

Using the above website...
215/55/17 are 668mm
225/35/20 are 666mm
Only 2mm different. That's only 0.3% difference in speed.
eg at 100kph they are only 0.3kph different. (100kph vs 99.7kph) Practically the same as Disciple.

awesome thanks for your help guys i have learnt so much since being on this forum, it's a real credit to you all :)
now i have piece of mind when driving and feel safer knowing i'm not over the limit etc

as for the engine and auto trans, 4.3 lts for engine with filter and transmission is 8.4 liters correct?

i normally put 500ml extra in as i have heard in the past especially with gearbox's
the front gears like that little bit extra as when you take off all the oil goes to the back of the gearbox leaving the front gears without as much oil?

Jaycar have a nice little kit (about $50) which allows you to 'tune' your speed, we use them on the track cars to over ride the ECU 200kph speed limiter. 3 wire attachment, very easy to fit, and a 9yo assembled the kit.

SMK380: Your Navman GPS will be far more accurate as an indication of speed than pretty much anything else you can use. Planes have been using them for eons (GPS that is, not Navman's lol) Also, I think what Foozrcool is saying, is that from the factory, your cars speedo reads fast, ie. off the showroom floor, when your speedo says you're doing 100km/h, you're most probably only doing about 94km/h. So what he's saying is, if you buy a different sized tyre, this can bring the speedo more into line with what your actual speed is, vs what the speedo is telling you.

I hope that made sense.

Neil,

Does this kit tune or adjust your speedo reading to correct it, or does it simply come with it's own display which shows your real/correct speed (a bit like a satnav)?

I've browsed the Jaycar site and I'm having trouble finding the kit.

KJ.

Edit - I think I've found it on the Jaycar site, here: http://www.jaycar.com.au/productView.asp?ID=KC5435&form=KEYWORD&ProdCodeOnly=yes&Keyword1=KC&Keyword2=KC

A bargain at $54.95 to get your speedo reading spot on.

Unfortunately it says 'out of stock'.

Spot on ;)

i'm going to run 100% synthetic nulon auto trans fluid they only come in 4L bottles so needing to buy 2 bottles plus need an extra 400ml lol
lucky i found some spare from the mr's car :)

You will need more than that to flush the transmission man. You will need a good 15L, so 4, 4L bottles for a proper flush.

I would stick to Mitsubishi trans oil for your auto... Mitsu auto boxes are very picky when it comes to oil, I know Pajero auto boxes have a lot of problems when you use anything but the correct Mitsu oil.

Picked up one of these kits today from my local Jaycar.

Way beyond my meagre abilities to assemble let alone wire up to the car, I know SFA about electronics!

I'm also wondering about how to connect it to the speedo wire, seeing as the 380 instrument/dash cluster connects via a multipin plug.

Seems it might be a complete dash out job, which would pretty much kybosh the idea for me.

Any auto sparkies out there able to give some advice?

15L wtf??? i just drained from the sump plug to give it a freshen up, i'm sure some of you guys have done this before? how much will it take by just doing that?

I didn't think the 380 had a limiter on it! Not that I have got to 200 kph though lol. Is this a definite ?

Most likely 3L? You need to dump the pan too then flush the torque converter with the car running. The process is in the workshop manual. The idea is that the gearbox takes 8L + 5L to flush.

they have a limiter at 205, although my black vrx that was an ex under cover had no limiter at 235 and was still going. Not that i tried it. lol but yes standard one 205.

I haven't been able to trigger any speed limiter in my 380 whilst driving on......

the track,private road,airport runway,back paddock, NT before speed limits,private road,the track,private road,airport runway,back paddock, NT before speed limits,private road,around dog kennel in back yard, chasing cows in holding pen..


If you do manage to push the envelope (on the track,private road,airport runway,back paddock, NT before speed limits,private road),

then be aware that the 380 ECU logs all the speeds above a certain threshold and may be called up for warranty claims....

KJ, you pick up the sender unit from the gearbox, down the back of the engine. We cut the signal wire (one of three in the wire down to the sensor) up the top, about level with the bottom of the battery. You do need a ignition on power source, we didn't bother, just connected straight after the battery cut out switch. The install took about 15 mins in the pits at Bathurst last Easter, but we did have a good guy with a multimeter. We dialed in 50% to give easy relavence to any displayed km/h and the car then had power all the way down Conrod.

I'm suprised you hav'nt found the limiter on an airstrip or in the NT, we have 2 ECUs, I thought the std one cut out at 200, but if it's 205 so be it, I also have an unlocked Engineering ECU that MMA sent me and it seemed to cut out at a higher speed (210/215) but not much in it.
