top speed limiter removal...

[EnjukuRacing240sx]

i just want to make sure this is the correct procedure... if someone could verify this for me?
on the computer, cut the yellow wire with the green stripe... its the 8th wire over from the right on the harness #32 on the computer?

cant clarify that for you, what i would do is just cut the 5th gear sensor on the tranny down there

hmm sounds like it would work... i just want to make sure that this will work first because i dont want to go under the car to do this unless this method definatly doesnt work... thanks

just unplug the 4th gear and 5th gear sensor on the tranny.

doesnt unplugging the 4th and 5th gear sensors on the tranny disconnect the rev limiter??

i'm listening.... i hate my revlimiter!!

cutting the wire will only allow you to go about 120. the rpm limiter in fifth gear is around 5000. The fuel cut is a nasty thing for the engine.

Does that work and does the tach still work? oh and why do you need to disconnect fourth?

[Bryants95240sx]

you dont have to it just let you wind out 4th more your tach should still work but your speedometer wont so youll have to wire up a switch if you want that to work.

every1 is sayin cut this and unplug that.. has any1 tried this on their own car an know that this works and doesn't cuz any long term damage to anything? cuz i mean i wanna try it too but i'm scared to cut anything then i gotta put out money to fix it

Why don't you guys just buy the speed cut and rev cut from hks? Save you guys the hassle of cutting up all your wires, and having a headache later. Do it right the first time.

i removed mine about a year ago all i did was splice one little wire, and wire it to my pop headlight switch so i can turn it on and off when ever i want no problems, no regrets, NO MONEY,NO REV LIMIT

this is my post from about a month or so ago heres the procedure from 240sx.org I actually just completed the task last week.It's not too difficult to do yourself as long as you have the ability toramp or lift the front of your car up enough to get to the transmission. Here's the procedure. First you must disconnect two sensors (presumably RPM limiters?) from the tranny. One is the fourth gear sensor, while the other is the fifth gear sensor. If you look at the transmission under the car there are supposedly four (4) sensors (I only saw three, but the fourth one is somewhere under there), the ones that need to be disconnected are the middle two (2). The electrical connections are simple snap lock configured so not cutting is required. Once the two connections are disconnected, I recommend you thoroughly tape over the ends of the connectors to prevent moisture from entering within.

By doing this step the ECU doesn't know your 4th or 5th gear RPMs, therefore it won't limit you. Note: If you have faith in placing your car on jack stands (some members have done this) you can test the limiter for each gear before and after each step. What you'll find is that the ECU limits the top end RPM for 4th and 5th gear before you disconnect anything. Afterwards, the skies the limit.

The last step is to disconnect a control wire that comes from the tranny area and passes by the passenger side of the starter in the engine compartment. You'll find another simple electrical connection (looks like a tube style fuse holder) with small gauge wire. Unhook this connection and then drive your car and you'll notice the speedometer doesn't work, nor do the number onyour odometer change. What you've disconnected is the sensor that transmits the speed to the ECU and the display. Now the computer tries to watch your speed to make sure you don't go past 115mph (S13 model, S14 may vary higher), but never cuts off your fuel since it doesn't have a clue how fast you're traveling.

Since most of us don't cruise over 115mph you may want to wire a switch into the speedo connection just mentioned. I used a simple red rocker switch and installed it into the blank Nissan console plate located to the right of my
rear window washer/wiper control buttons.
now you dont have to install a new switch i just wired it to the head light pop up switch cause i didnt ever use this button

Which wire did you splice and does your speedo and tach still work?

*EDIT* Never mind. I understand what you did now. Thanks. I'm looking for a way to get rid of the fuel cut and have the speedo and tach work.

[EnjukuRacing240sx]

yeah thats what i was wondering

[AWDSR20]

no rpm at 4th and 5th??? huh... not tanxs! i rather get the HKS one!
