speed limit cut for japan engine

[r60262]

hi guys..... i already install speed cut limit but the prob. it seem nothing happen. same like before. i don't know that prob. come from my engine or this unit. i use ultra brand. ( from japan) other funtions on this unit is rpm, odometer, miliage, oil, & trip also have memory. i use toyota engine silvertop at seg car....

 

[huakenny]

r u sure ur car can exceed 180km/h???

 

[apeng]

most probably u cut and tapped to wrong wire...
since last time it happened to me...
after tapping to the rite wire at ECU, it's works.....

 

[g88]

i think your speed cut wiring didn't tab properly...i used Pivot Speed Meter X...one wire need to tab to ECU speedo sensor input and another to speedometer sensor....

[jockchan]

300 km/h also slow la 400 km/h fast la

 

[youmolo]

sorry for asking, but what's the speedcut on a silvertop? 180kmh?

 

[kwai]

i think all japanese domestic car have the speed cut things...

same case with my halfcut...

dam lost stim when reach 180km/h but kena cut...

dann geram when pulled away by merc coz of the 180km/h cut...

r60262,
make sure your ultra gadget really have the eliminated speed cut functions...
if its really have, double check the manual book, whether the connection is correct... :D

 

[g88]

i think most of the japanese car speedcut at 180km/h

 

[kiran84]

Yup its 180km/h

As it was my speed cut on my 4age 16v non tvis

After fitting a speed cut remover, so far tested 220km/h on KLIA road............after that not berani oready.......................

wad happens when u reach 180 when you have speed cut? i know my bt has rev limiter la. the engine like wanna die when reach above 8k rpm. but i can go above 180kmh. the only problem is my speedo ends at 180kmh so the needle just goes beyond that.

 

[r60262]

hi all.
1stly i'm sorry if i wrong. also my english very bad. i new in car modify. i have auto silvertop. before i fitt speed cut remover max speed i test is 175kmh. after install that speed cut remover also same. i dont know if my car perfoment can exceed 180kmh or not. or my wiring is wrong. when off/drive (3rd gear) my car can reach 160kmh but after on off/d i only get 175kmh.... long br dpt. can you all teach me something.......

 

[youmolo]

maybe ur car can only reach 175kmh cuz auto tranny got torque converter and at high speeds they tend to slip. just my theory ;)

 

[kwai]

if you have speed cut, when your meter touch 180km/h, even though you floor the accelerator paddle, you engine also will sudden cut fuel...

is like you suddenly let go the accelerator pedal~! then a big jerk....

if you still keep ur foot on the accelerator pedal, your car slow down until certain speed(my car 160km/h), then continue accelerate back....

 

[fritz]

Erm..youmolo..u try to speed..over the 180km/h mark..if the speed limiter in function, then u will found tht ur speed will be lowered to around 160 or 170..cant remember.
U always rev till cut? I heard those toyota sifoo say cut 3-4 times engine habis one oh~hehehe!!!

i dun think the speed limit will behave like this...it will not jerk the car...but it will like the car cant go anymore...the speedo will stay at 180 and will not bounce back..

if ur engine/rpm will bounce back and need to accelerate again to reach the 180, i think it's ur gear are finished it's speed and u need to change to higher gear.....it's just like u over rev the first gear..
but in sec, third and fourth or even fifth gear, then bounce back will slower nad slower ..not like first gear.........

 

[detomaso_runna]

howiechoo..... i think whut chai said is rite.... it will bounce..... fuel cannot go in engine ma.... my engine also bounce back.... meter full.... already pass 180 then bounce back... till 160 then can accelerate again..... if gear finish i wont bounce back wan.... if gear it will stay.... your theory is wrong.....

any sifoo here wanna comment?? mayb diff engine diff style of speed cut... mitsubishi sure bounce back.......

 

[youmolo]

thanks guys for the explanation. i can go until the meter needle pass the 180kmh mark, and then the needle will just stop there cuz no place to go anymore. but i never experience any jerking or reduction of speed till 160kmh. i dunno if my meter reading correct or not.

not always rev until cut la haha got a few times rev too high until the engine spluttering. 3-4 times engine die meh? so fast?

i tink when the speed cut is functioning, it works exactly like the rev cut: it limits the amount of fuel going into the engine. cuz u cant limit the air going in, so that's the only way. when u limit the fuel, the engine will jerk la.
