3rd gen 3sgte speed limiter?, does it have one? Options

[urbandork]

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

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?

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).
