Speed Restrictor

[gfro]

hey.

my r32 gtst seems to be restricted to 180kmh, NOT HAPPY! just womdering if anyone has a cure for this inconveniance??

i've heard that u can buy some sort of chip to bypass this or will it need some ecu tinkering??

any and all info will be greatly appreciated,

thanks Sam.

um... mod the ecu to remove the rev and speed limiter? its a 5 minute job. you'll need a soldering iron, an EPROM and an eprom flasher.

or just cut the speed sensor wire the the ecu. Wire 53 for the GT-R, I don't know what one it is for Gts-t

[guesty]

Wont you lose the speedo as well then?

[4drftn]

u can by a unit for it of if you have or get an aftermarket ecu it will cut it out...

not in a R32, the wire comes out of the speedo, and spilts into a few differnt places. SO you just have to cut the wire at the ECU

why would you want to go over 180 in a stock 32? it would be boring

[funkymonkey]

the speed signal also affects your HICAS and ATTESA (if you have a GTR or GTS4) so I wouldn't go cutting it. I mean think logically, Nissan's not gonna have a speed sensor on a mechanical speedo equipped car for no reason.

If you have a GTSt with no HICAS then you shouldn't have any use for it.

Go get your self a Remap from Dr Drift ( SAM ) in melbourne or

Buy an Apexi RSM as they remove speed limit and you can move the rev limit

Or i have a Blitz ID Speed Meter Which does the same thing which you can buy off me

Cheers

I traced all of the wiring when my HICAS played up, 1 wire comes from the speedo to a spitter, then from there 1 goes to the ECU, 1 goes to HICAS, and 1 goes to ATTESSA. So if you cut it at the ECU it won't affect the others.

Oh ok. that must be the reason why mine stoppped working in the 33 when i cut the wire.

because out at baskie i do 165 - 170km down the back straight and with a few decent mods i have planned i will be hitting the restricter and we dont want that now do we.

also thanks for the responses everybody, keep 'em coming!, i'll have a look at my ecu wiring asap.

r32gtrpowa how much u want for the speed meter?

[gfro]

also funky monkey help this noob out, wats an eprom and eprom flasher

[sav man]

if you have a new ECU planned in the list of mods that will fix it, the factory ECU is what restricts the car the 180.

cut the wire and place a switch in line to turn on and off when needed to do that over 180 track speeds!

I like this idea, it's some rocket switch sh!t hey!
