Rev limiter?

[SiVaK]

Ive searched through the forums and cant find anything that could explain what ive come across... in 5th gear my r33 gtst s1 rev limits at 5000 it bounces and wont go any further,im past 180kph as well so its not speed limiter plus this never happans in any other gear only 5th?? Has anyone come across this before?

[siksII]

are u sure you have had the speed limiter removed

??

when the limiter cuts in, the car will indicate well past 180...

at about 5 grand is actually 180 in a r33 gts-t so i would say it is the speed limiter.

i hope you are testing this on a private road

Hrmm well the speed varies whether going uphill or downhill when im hitting 5000 in 5th which is when its cutting.....i thought the speed limiter cut the revs when it got to exactly 180kmph this is why i thought it may be something different because im going well past 180 downhill in 5th doing 5000revs...on a PRIVATE ROAD yes... =]

In my r33, the speed limit was at 192km/h as read on a gps speedo, its miles past 180 on the speedo. Pretty sure thats what you're hitting.....acceleration just stops gently?

[Tosh]

speed limiter for sure

[SiVaK]

Yup that sounds just like it Duncan but its always perfectly at 5000revs (by eye on stock dials) does that sound right?

[R33vit]

Sound about right

[Duncan]

muahahah HIJACK!

Sam, are the ratios in yours for an R33? I thought they were:

1 3.875

2 2.14

3 1.384

4 1

5 0.694

You have

1 3.214

2 1.925

3 1.302

4 1

5 0.752

:confused: I don't have the manual, can anyone confirm?

[dojobi]

Duncan, those ratios you've given are for the 5 speed auto in the GTS25. Sam's are right for the manual.

[Duncan]

:Oops:

[SiVaK]

Yup sounds to em like its the speed limitor,i used sams gear ratio calculator and it adds up thanks.

NOW how do i get rid of it? ive heard things about cutting wire 53?? is this right and where do i find it?

[SiVaK]

Anyone wanna touch this? haha

[Tosh]

buy an Apexi RSM or HKS Speed Limit Defender

[carlo]

My RSM reports my top speed to be 190kph.. The 5000 rpm limit will be either boost or more likely speed cut.

Fix it by getting a defender or aftermarket management. I dont really think you have to tho for most things, the only time you get past 190kph is at EC.

[Tosh]

but didn't you wire your RSM to keep the speed cut as you were planning on buying an aftermarket ECU anyway Carlo?

This is correct. As mentioned above by Duncan the speed cut on the ECR33 seems to be 190ish as opposed to the popular belief of 180.
