well tonite on the freeway on the way home i got the car up to around 120 and then it kinda shut down as if there were a speed limiter on it? it felt exactly like what happend when i hit 118 in my 01 corolla. At first i was worried that some how i hit the boost fuel cut as i was giving it a good amount of pedal, however when i easied my way up to 120 it did the same thing as well.

what happend? is there a speed limiter on the 3s ecu? and how do i disable it?

thanks

Yes all factory JDM motors are limited to 118 mph IIRC. To disable it you need to cut the Purple wire with the white stripe on the 22 pin connector. Expect CEL on if you do that so you might want to get a switch on that wire so its not permanently cut. You MIGHT experience issues with power steering and/or speedo gauge. I have not removed speed limiter on my gen3 so i cant confirm this info, its just what i found out from reading. The best way would be purchasing one of HKS or GREDDY speed cut defencer (~$100) or going standalone

any one try either jsut cutting the wire or that hks thing? what are ur impressions?

>The ECU needs to see the speed sensor input or it will throw check engine lights (and probably limit boost, etc.). It would be better to use the speed cut removers from HKS or Greddy or whatever (I haven't decided if I will do that or a standalone on my gen3 motor).

Oh, and the speed limiter is at 180km/hr (or 112mph). It really sucks when you are just getting up there in 4th, huh?

115 for me, is it easier or the same to remove speed cut for a 2nd gen JDM 3sgte?

what exactly does that hks speed cut remover do? I like to know what things do exactly before i put them in lol


and yeah it does suck when ur just getting to a good place lol..... its kinda like blue balls

u got ur swap up and running? thats nice lol

just dont sell it

>It interrupts the speed sensor signal before it gets to the ECU. The signal is passed through up to a certain point, then limited to a speed that won't trip the speed cut. It should be really simple to wire up (power, ground, signal in, signal out).

which ecu box is it located in is it the one in the footwell?
