Removing RS2 Speed Limiter

[GT500]

Just gave my RS2 the beans last night, bang on to the speed limiter!
I was a bit surprised! I would have thought the MTM chips would have got rid of it!

Defo limited to 163mph. Mihnea informed me he removed the limit when re mapping. Never did test what it did & I am back with the OEM maps at the moment.

I agree as Mihnea said something similar to me when mapping my car. In fact he even set it at 40 mph for a minute or two to wind me up!

It worked too, the cars ignition was cut at 40 mph. My car has now been set at an untouchable 199 mph

Hello Skaala,

I didn´t try removing the limiter yet because I had some eletric problems with my ECU, but as soon as I try it, I´ll let you know. Sorry for tooking so long to answer you!
Did you try it yet?

Best regards

Just remove the coding plug attached to ECU wiring loom - inside the Apillar on passenger side near the ambient/altitude sensor.

did you find out anything Nilo? I want my limiter removed as well.

Hello you guys,

Thanks for the prompt answer to my question! My car certainly has a limiter, since I´m running 1.6bar boost on the original K26 and It stops at 270km/h (on the clock, that is) like hitting a wall!
I was told about that pin cutting thing, though I was a little bit worried about the consequences of doing that. Didn´t know if it was going to cause me any trouble with the ECU, so I thought it would be a nice idea to ask on the forum if anyone has done that!
So, the thing is: is it safe to cut pin 38 to remove the limiter, then? Has any of you guys already done that? Any help will be much apreciated since even the Porsche dealer around here seems to be unaware (or unwilling to tell) of that!

Best regards

Nilo

P18 of the RS2 workshop manual. Coding 4 applies a speed limit of 270km/h

The limiter can be removed by applying coding 1. disconnect pin 38 from earth

I quote that.

RS2 has a speed limiter in the ECU

fair enough! the RS2 documentation doesn't show a limiter only that the top speed is 262 lm/h

Live and learn

All the test reports I have in old magazines state that there was a 262km/h 163mph limiter, and that it could be ordered without as an optional extra. The limiter isn't on the speed it self, but on the revs in 6th gear.

Are there any other effects (malfunctions?) on the car if you snip the earth wire as mentioned in the posts over?

How can the speed be limited to 270 km/h when the RS2 top speed is 262.3 km/h according to the specs??

Has anyone got any official documentation on this?

3B 5 Speed ARV box will do 188mph (302km/h) at 7200rpm, if you could hit 7650rpm in top it would pull 200mph (320km/h)

ABY 6 Speed CGR box will do 184mph (296km/h) at 7200rpm, you would need 7850rpm to hit 200mph (320km/h)

hey something else the 3b is better over the aby

I've known about the longer 3rd gear but thought that there was no difference over top end, now I know different

My RS2 is completely stock, and I hit a wall at 262 km/h (GPS speed) on the autobahn, It clearly wanted to drive faster but the limiter cut in, smacking the revs down and the speed to 255km/h

what´s the max speed limit in our gearboxes??? around 320 km/h maybe?? and with the 7A cams for broke the red line??

Maybe its something Porsche wanted on the car...

and me with my 3b, i had sometimes 260KM/h at 6500rpm... and 280km/h (180mp/h) at 7000rpm of course in the speedo,with GPS its the best mode to know how many speed we have. ALL i,ve tested in private tracks of course
