how do i know this?
i can hit 180k on a flat surface pretty solid according to the speedo. on a downhill i topout at a bit more then that before i govern and on an up hill i govern a bit bellow 180

so explain to me how my speed limiter changes according to the angle of my car? unless honda has some pretty seriouse gizmo's int here lmao.


its a rev limiter plain and simple.

You have the right idea. it sa simple switch to say "shut off fuel pump" now two questions. is this a seperate wire that tells it to shut down. or something that tells the cars brain to stop pumping gas. cause its two different methodes.

if tis a seperate line then its simple to find said line and create a break

BUT if its int he cpu. I.E. the cpu in the car is reading the rpm gauge and is also running the fuel pump is coded to decide at a set rpm to shut down the fuel pump. the only way around thi i can see that is simple would be to find teh RPM sensor and isntall a switch to disable it completely. which would do two things.
one kill your tach int he car,
two stopt he cpu from also reading it. which MAY cause some errors.

now at that time. figure out how it sends the signal.. does the rpm sensor send a voltage to the cpu which then tells the cpu by the voltage +/- how fast its going. make sense? kind of like a meter.
if it does it this way. fidn out what voltage it sends at 7000rpm in 5th cause they should all be a diffrent source soo.. um how can i explain this

in 1st at 2000rpm you cars rpm sensor is sending a 1.2vdc current tot he cpu so the cpu says OH ok thats this speed displays this rpm to you and calculates etc.

so in 5th once u hi the limit. say 7000rpm its sending a 11.3v signal?
install a switch with a proper resistor.
so its sending 11.2 about to hit the 3 to kill the pump, but you click on the resistor. knocks that source back a few numbers and bam your internal rpm is way off BUT your cpu is also readin something wrong.

if i could find the wire i could test this theory myself. it may be a resistor and nothin more lol

***the above information is exactly that. and is jsut my thouht process over this discussion using my knowledge that i ave aquired. i have no degree or other bs so this is just a few possibilities. i may be right i may be way off
thought i'd toss it out there

find the RPM sensor and you can killt he govenor. one way or another

find otu hwo to disable the rpm sensor for the stock ecu. add in your own ater market tach and you should be set to giver

the cars BUS, or combined system of all the computers read signals and communicate using 5 volts not 12. so it wouldnt be 11.4 volts or w/e u said. and some,not ours but some, read off 1 volt for some sensors. and second, you dont just go wiring in resistors to voltage signals because you can fry your ecu that way, and the rpm reading is used on many many more things so dont think that this wont **** up more ****!, plus rpm is read from the camshaft and crankshaft sensor. and rpm signal voltage doesnt matter what gear your in, how is 2k rpm diff in diff gears? its still 2k.
again sorry if i come off as a **** but i havent had the best few days and im honestly just trying to let you know this stuff.
i like the idea of switching though, maybe i could figure out the best way to wire in a relay and switch into this circuit so i can keep the rev limiter for driving and remove it for top speeds!
i thin what ill do is get my multi-meter or one of the test lights that doesnt draw current, and ill leave the car in neutral, revving it watching the signal. then ill bounce the rpm off hte 7k rev limiter and watch to see if the ecu is grounding the circuit to cut fuel. i have no clue when i could get arond to this since im fixing my car


no way, all it takes is someone who knows and understands automotive electricity, and can diagnose symptoms, thats all this is, diagnosing the symptom of the rev limiter kicking in, hell i think even a mechanic ase certified in auto electricity could do it (thats me lol )
