speed limiter question again

[Vatche]

ok so i searched through every single speed limiter thread and there is not one thread which tells you where the 4th gear sensor is located on the transmission for the sr20det i found one thread that said where the 5th gear one was, is that for both 4th and 5th or just 5th. and thats about it. someone please help me locate these things and for future searchers thanks.

if you want to get rid off your speed sensor? 2 options:

1: buy a auto matic ecu and there is no rev or speed limitor
2: run a switch for the speed sensor before the ecu and when you are racing or what ever you are using this for just flick the swithc your speedo will drop to zero and trick the ecu that its not going past 110 and you can go as fast as you lil heart diseres

for an sr20det
1. why buy another ecu....takes too much money what im doing is free.
2. why run a switch you cut a wire on the ecu yellow with green stripe and grey dot blah blah and your speedometer still works. because as explained in other posts the vss vehicle speed sensor goes to speedometer then the ecu.
3. there are supposed to be 2 sensor plugs on the tranny that you unplug and it doesnt tell your ecu that your in 4th or 5th so that your limiter doesnt kick.

thats far as i know not for an sr? but it doesnt matter he says the two middle ones, i only saw one plug in the middle and from what i read on another post its the 5th gear sensor....so where the hell is the 4th gear sensor...thats what i wanted to know. we should add pictures of this for the future and put in the archive instead of the other shitty write up that doesnt explain anything.

[IAM_SO_sLOw]

i dont think you need a speed limiter for 4th...for my car i could go past 110 in 4th and when i shift to 5th it wont let me go past 110 at 5k rpm iirc..

im thinking about cutting my speed limiter (for el mirage) i was wondering if it would take out my rev limiter tho... because i wanna keep my rev limiter so i dont blow my engine =XX

[Vatche]

well from my experience on my car, i cut the yellow wire and didnt remove the 4th or 5th gear sensor because i didnt want to blow my motor. what happened was my 4th gear went from about 6800rpm cut to a 6000-6200 rpm cut basically from like 105 to 100 or whatever ...just enough to bother me..and my top speed got up to 130 from 116. I didnt like my 4th gear being lower because i would rather have a good race through 4th and stop at 116 then go up to 130 but be slow at it. So i hooked my wire back up and left it that way. Now I decided to do it right and unhook the sensors at the tranny, i dont know if that removes rev limiters. i do know from reading that all it does is tell your ecu to limit speed at a certain rpm in that certain gear. So i am testing this theory out.

[Gutling]

my sr20det was speed limited to 120 (very top of 4th)
and "doing it the right way" lol is never unhooking sensors somewhere. I got rid of mine through a enthalpy ecu. still got rev limiters

[projectRDM]

All wrong info. Unplug the 5th gear switch and the VSS. Done.

The speed limiter kicks in at 120MPH, or when the car sees 5k RPM in 5th gear.

[Vatche]

ok well i ran my car today to see if my speed limiter would hit. before i unplugged my 5th gear sensor, or what i think to be that sensor and before i cut my yellow wire my 4th gear went up to 7k and my top speed was 116mph.
After i unplugged what i think to be my 5th gear sensor and cut my yellow wire my 4th gear rev limiter hit at 6200-6400 or so and my speed limiter(might be my 5th gear limiter) in 5th gear hit at 122.

this is for a redtop sr20det. so if anyone knows what the fuck is going on let me know. and if anyone has a picture of where the 4th and 5th gear sensors are on the transmission that would be great too.

and your right im not doing it the "right" way , im doing it the cheap and free way. because i dont have 500 dollars to spend for a service like enthalpy. otherwise i would take my car to him and have him do it so it would run better too. and this cheap way works for most people. im trying to figure out how to do this the correct way so people dont have to spend hours searching next time. there are like 50 threads on this topic and none of them are specific or right.

[Gutling]

how do u know ur car is hitting 116mph, or 122mph out of curiousity?

[SilentSamurai8]

Funny...I just got a HKS SLD, or Speed limit defencer from option imports .com and have never had a problem sence.

I use to have a limit at 110 but know can hit 160 easy. Got buy one and forget the stupid ecu/tranny crap.

[Vatche]

i would never spend money on a device that only takes away your speed limiter. i would rather have an ecu done by enthalpy or get a piggy back.

i know i hit 116 and 122 because my speedometer works. read before you post vss->speedometer->(cut it here)ecu

[Gutling]

oh i guess u have hud, i was thinking the speedo stops at 110or115 lol why i was confused

[Vatche]

yeh i have a hud, but i still dont have any responses on which one is the sensor, im pretty sure i unplugged the reverse lights. so which plug did i unplug. comparitively speaking to where the 4th and 5th gear sensors are?

[Vatche]

doesnt anyone have an answer to where the 4th and 5th gear sensors are on the redtop tranny? i would like to fix this.

[projectRDM]

Two issues here.

SR gearboxes don't have the 4th gear sensor.

You cut a 'yellow' wire? VSS is yellow/green. You cut the wrong wire. 5th gear switch is yellow/blue.

Go under the car, unplug everything, drive it. If you have no limiter afterwards, you're done. Plug the VSS back in and cut it after the speedo, before the ECU. This really isn't brain surgery.

[Vatche]

ok well thats great news someone finally explained what i needed, when i have a chance i will keep you all updated. but for now i did cut the yellow with green stripe and gray dot, which i beleive is the right one. the wire i unplugged was my reverse lights so i have to get back under there and plug that back in and try the yellow/blue wire for the 5th gear sensor....my question now is why is my 4th gear rev limit lower then before i cut the yellow with green stripe wire from the ecu.... if you can help me figure that out it would be great.

[Vatche]

does anyone know why my 4th gear rev limits at 6100 rpm instead of what it was before i cut the vss, which was like 7000 or so?

[Vatche]

question still stands

[turbotractor97]

yea im experincing the same problem

cut wire

but ihit a wall at 110 in fourth and its just too soon
to shift into 5th gear
but 5th will go past 110

[HyperTek]

dam man your lucky to hit a wall at 110 and survive..

lol

yah russ ftw, you could allways run 2 wires up and a switch lol, put one of those cover switches, and write on it DEATH. "on" "off" road rage? anyone lol

id say those limiters save lives :keke:

[g6civcx]

I understand the limiter issue from both sides. It's unsafe to go that fast in any car, but again it's annoying to bounce off the limiter on the main straight.

Take your trusty multimeter and go to the gearbox. Leave the gearstick in 5th gear. Unplug the different switches and look for continuity across the 2 pins. Whichever switch has continuity is the 5th gear switch.

[cotbu]

There is no cheap, right, or easy way for the sr tranny! The failsafe kicks in if you cut the yellow with green stripe wire(some as low as 4800rpm in 4th). 4th and 5th gear sensors on the KA tranny can be unplugged, the SR tranny has neutral position and reverse sensors on the tranny along with the VSS. If you cut the wire for the VSS, then you may make it past the 180km limit but... if you can't see how fast your going are you really going fast.

The best way is a, DIY TUNE (bikirom) next, Upgraded ecu (enthalpy) then, speedmeters (pivot) Lastly Backup ECU (an Auto one)...

[bardabe]

hmmm so Im guessign I must have some wires in my tranny mixed up. he he I have a 62 ECU and uhhhh yeah I get my speed cut in my 3rd gear when it sees 5K RPM's .... snesor wires mixed maby???

[Vatche]

yeh i gave up on this stupid thing for the sr. its so much cheaper to wait and get a tuning device

[Rayne]

if you want to get rid off your speed sensor? 2 options:

1: buy a automatic ecu and there is no rev or speed limiter



The automatic ecu with an automatic transmission has a speed limiter set at 110. I believe the rev limiter is set at 5,000 rpm in 4th gear.

I am guessing people are saying there is no rev limiter with automatic ecu's because the automatic transmission only has four speeds and the ecu does not recognize the fifth gear for the manual transmission.

I am in the process of doing the five speed swap and will test my thoughts after everything is swapped over.
