is it? I am aware of thinner wheel 45 instead of original size 50. It may be totally offset from orginal tyre but just minor affect on the speed...

I though the original tyres are 215/55-17? if so a 235/50-17 will be the closest overall diameter.

A 235/45-17 tyre will put your speedo and odo out by about 4%

+1 yup wot he said. So when your speedo reads100kph you're actually only travelling at 96.3kph. On the bright side that's in your favour when going thru a multinova and you'll clock up less K's on the odo than you will actually do :thumbsup:

So if speedo reads 100kph and actually travelling at 96.3kph wont that mean that odometer reading of 100km will actually be only 96.3km travelled and hence will clock up 4% more kms than the odometer reads????

FIXED.

but yup you're right sorry my bad..............DOWNSIDE you'll clock up more K's on the odo than you've actually done.

Hey guys just my two cents, i run achilles on my V35 (sedan) 245/35r20, for the price they are they are awesome tyres done 20000 on them daily driving (i drive pretty hard on em too) got at least another 30000 left in them and and they stick like glue and have like no road noise. Also i better mention that we at bridgestone have just launched 2 new tyre ranges the MY01 and the Turanza serenity, but i cant vouch for them personally yet as i havent even seen them yet because we only released them on the 3rd of this month

Hi Guys, I had one of my front tyres punctured (Bridgestone Potenza) and need a new tyre to replace that without having to spend too much. I have been quoted Sumitomo (HTR I think) $220 and Hankook K115 $190 fitted and balanced.

Any thoughts on that anyone?

By law your tyres must be rated to do a sustained speed equal to your car's top speed, regardless of whether that speed is legal or not.

I'd get that stuff right, as cops check that data when considering whether to defect your tyres as roadworthy or not.

What a load of rubbish.

The only legal requirements for tyre fitting are that the speed rating of Australian passenger cars be rated S or better and that the load index of the tyres meet or exceed the manufactures spec found on the tyre placard in the drivers door. There are other rules like tyre cannot ride outside of the body etc but basically if you meet or exceed the placard you are good to go.

FIXED.

but yup you're right sorry my bad..............DOWNSIDE you'll clock up more K's on the odo than you've actually done.

Sorry to hijack the thread but is it possible to get the speedo calibrated that it shows the correct speed?

    • You won't need to do that if your happy to learn to tune it yourself. You 100% do not need to do that. It is not part of the learning process. It's not like driving on track and 'finding the limit by stepping over the limit'. You should not ever accidently blow up an engine and you should have setup the ECU's engine protection to save you from yourself while you are learning anyway. Plenty of us have tuned their own cars, myself included. We still come here for advice/guidance/new ideas etc.  What have you been doing so far to learn how to tune?
    • Put the ECU's MAP line in your mouth. Blow as hard as you can. You should be able to see about 10 kPa, maybe 15 kPa positive pressure. Suck on it. You should be able to generate a decent vacuum to about the same level also. Note that this is only ~2 psi either way. If the MAP is reading -5 psi all the time, ignition on, engine running or not, driving around or not, then it is severely f**ked. Also, you SHOULD NOT BE DRIVING IT WITHOUT A LOAD REFERENCE. You will break the engine. Badly.
    • Could be correct. Meter might be that far out. Compare against a known 5 ohm 1% resistor.
    • @Murray_Calavera  If I were an expert I wouldn't be in here looking for assistance.  I am extremely computer literate, have above average understanding on how things should be working and how they should tie together.  If I need to go to a professional tuner so be it, but I'd much rather learn and do things myself even if it means looking for some guidance along the way and blowing up a few engines. @GTSBoy  I was hoping it would be as simple as a large vacuum leak somewhere but I'm unable to find anything, all lines seem to be well capped or going where they need to be, and when removed there is vacuum felt on the tube.  It would be odd for the Haltech built in MAP to be faulty, the GTT tune I imported had it enabled from the start, I incorrectly assumed it was reading a signal from the stock MAP, but that doesn't exist.  After running a vacuum hose to the ECU the signal doesn't change more than 0.2 in either direction.   I'll probably upload a video of my settings tomorrow, as it stands I'm able to daily drive, but getting stuttering when giving it gas from idle, so pulling away from lights is a slow process of revving it up and feathering the clutch until its moving, then it will accelerate fine.  It sounds like I need to get to the bottom of the manifold pressure issue, but the ignition timing section is most intimidating to me and will probably let a pro do that part.  Tomorrow I'll try a different vacuum line to T off of, with any luck I selected one that was already bypassed during the DBW swap.  (edit: I went out and did it right now, the line I had chosen did appear to have no vacuum on it, it used to go to the front of the intake, I've now completely blocked that one off at the bracket that holds several vacuum lines by the firewall.  I T'd into the vacuum line that goes from that bracket to the vacuum pump at the front of the car, but no change in the MAP readings).  Using the new vacuum line that has obvious vacuum on the hose, im still only getting readings between -6.0 and -5.2.  I'm wondering why the ECU was detecting -5.3 when nothing was connected to the MAP nipple and ECU MAP selected as the source. @feartherb26  I do have +T in the works but wanted to wait until Spring to start with that swap since this is my good winter AWD vehicle.  When removing the butterfly, did it leave a bunch of holes in the manifold that you needed to plug?  I thought about removing it but assumed it would be a mess.   I notice no difference when capping the vacuum line to it or letting it do its thing.  This whole thing has convinced me to just get a forward facing manifold when the time comes though.
    • Update: tested my spark plugs that are supposed to be 5ohms with a 10% deviation and one gave me a 0 ohms reading and the rest were 3.9ohm<, so one bad and the others on their way out.
