Speed Limiter Controller

Speed Limiter Controller
I don't know if this has been mentioned, but HKS makes a speed limit controller that can disable the factory speed limiter. It says it's universal but I don't know if it's been tested on a TC.

Or maybe I'm just a dummy, but I thought it was interesting.

Also, what about reseting the ECU? Just disconnecting the battery cable for a while and pumping brakes. I heard that someone did that and it stopped the fuel from being cut. He said it went from 127 to about 148 (he thinks) at 5900 rpms.
Can someone confirm this? Very interesting "upgrade".

no your right.............i was reading the manual one night before i even bought the tC and there is a fuse for the limiter. its not in the main ecu either............at least i think that what i read. ill look through it again and see if its right. might be for something else but i saw limiter and a fuse for it and thought speed limiter.

Definately check into that.
Does anyone even know yet what color on the ECU the speed sensor wire is? I installed the Apexi RSM-GP on my tC and it has a speed cut defense system built in. Just need to tap the correct wire.

there isn't a TRAC fuse for the speed limiter like there are on older cars like the JZ supra engine. it's programmed into the ECU, the only way around it is a piggyback or reprogrammed ECU, I'm not sure if that will work or not but Scionspeed is working on it and they are very close to a solution.
oh, and the theoretical top speed of gearing on a manual is 139.4mph with stock tires. auto is 163.7mph @ 6247rpms but you would need OVER 340whp to overcome drag to get up to those speeds.... the Scionspeed stage 3 turbo ought to be able to do that... here's a pic I stole from another forum, property of Zoltiz

I saw a product advertised on spike tv this weekend... It plugs in like an error-code reader but then you can reprogram parts of your cars computer.
i think they specifically said the top speed.

hrmmm im just tired of running threw 1st and 2nd gear and hitting the limiter.
im used to having my old bmw that i could go ALL the way threw redline. where the TC just hits the line and limiter kicks in...I HATE IT!

Just out of curiousity, WHY are you trying to go past the rev limiter? It's there for a reason, you know. Are you trying to blow your engine? You do realize you are past the optimum shift point in terms of the power curve.
Unless you are doing forged internals or other internal engine mods that could handle an increased redline, you're only causing unnecessary damage to your engine.
