Anyone Know How To Remove 180km Speed Limiter In R33 Gtr?

[bonestorm007]

Hey all,

Have a 1997 R33 GTR, making 239 RWKW with standard computer. Am quite happy with that for the moment and want to keep the factory computer for a while. Unfortunately was hitting the speed limiter half way down the straights at Sandown.

Anyone know how or who can cheaply remove 180km speed limiter in r33 GTR while retaining the factory computer????

Cheers,

Luke.

you need a after markert computer or a hks fcd maybe

ok have you ever taken a look at the computer? its at the passanger side

ive never tried this myself...since ive never owned an R33....

but apparently there is a wire to the Computer labelled No#53...

cutting this wire....taping it up would disable the speed restrictor....

cutting any of the wires...you could always join it back up...so if i were you, id give that a shot....

why do you need to remove it? because how are you going to test this out?

this would be the "cheapest" way without modding the ecu

make sure you let us know how you go on this.... should this work, ill post it up on the DIY section for future reference. Im pretty sure we need this one in there

or u could just get a fcd and know thats its gona work 100% without butchering your car

[joeyjoejoejuniorshabadoo]

cutting 1 wire is not butchering the car, yo can EASILY join it back up

[frx026]

easy and safest way is either

HKS - SLD - Speed limit defender

or

APEXI - RSM

either one will remove the limiter, although I would go the apexi, at least it will give you a few other functions you might find useful on a track.

That's safe and nearly $500 retail for the Apexi unit

Wire #53 is commonly known as been able to be cut (according to the SkylinesDownUnder I believe), I never tried it personally as if you have an aftermarket ECU you won't need to do that trick

ermm both you guys i dunno if you read his question...... he asked for the CHEAPEST way possible..........

hes "happy with everything" for now.......so he didnt really ask for jibber and jabber or gidgets and gadjets....

i think this is the most efficient way to suit his needs

do you know if this will work for a gtst is it the same wire .... i have heard of this before and was told that #53 wire is the out put to the ignition module when the computer switchs it to earth the ignition is disabled if this is true its a verry easy cheep and safe way of disabling speed limiter im sure you have to cut more than one wire to install one of the hks or apexi units listed above so why would this method be dodgy

[fuzzy_scuz]

If you are in Melb I have stock ECU with a Speed limiter over ride connected to it already. For you to look at. This was installed by AVO.

This should give you an idea of what is required.

the apexi rsm can be had for $300 direct from the usa..

and i thought that was really cheap.. 300 bux is nothing.

[leetom]

pivot speedmeters are pretty cheap and will remove limiter, cutting no53 is obviously the cheapest but you guys with autos better do a search cause i think its a no no.

[CR34M]

I've heard you can melt the limiters by travelling at the max speed (this being 180k) for at least 5 minutes at a stretch...the fun part would be finding a stretch of road that is suitable for 5 mins worth of flat out driving at 180Km/h...That overides them without having to buy a limiter defence cut thing.

Or you can do that on a dyno

I heard this from many people not just a few of em and a few people who have actually succeeded in doing so. So its worth giving a try i guess, just run your boost on low and gradually make your way up to the speed ona dyno and leave it there for as long as needed.

Don't know how reliable this is since i havnt done it myself...but worth a try like i said....

i think it is the same wire. have a look at the ECU.. apparently the R34 is wire 29# or something but 32 and 33 has the same.

yes i recon... people are forgetting how Stereos, speakers, Alarms, Tachos, immobilisers are installed.....

no body solders things anymore.... its just snip snip.... and electrical tape it shut....

i think its worth a try... and if its no good.... just tape it back up...

sweet cheers might try it tomorrow ill let you s know how it goes

lol

you seem more keen than the OP...

yep, definately keep us posted and you could be the first to POST a DIY. ive checked and there isnt one there regarding this

[Walfers]

Old as bump,

my 32 GTST has got a 25 Neo in it, am i safe to cut wire #53 until i buy a Apexi RSM or something similar? Hicas has been deleted.

[Ben C34]

Get a nistune.

Hi,

ECU PIN 53 is the VSS input to the ECU and cluster.

Cutting this wire I would say will disable the speedo itself.
