Hi im new here and was just wondering has anyone at all hooked one of these speed cuts up to their aristo?
I have a 96 Black gen 1, 3grand stally, fmic, catback exhaust. lowered on superlow springs with 18" BBS wheels with 235s on front with 275s on rear.
my best 1/4 mile time was 13.2@104mph at townsville dragway in queensland

i just wanted to no if cause the speedo only goes to 180k/ph and i do like 240k/ph will the speedo needle be damaged and if anyone has the pin location for the speed signal ecu wire and the speed signal (sensor)wire

PM me your email address and I'll send you the Aristo ECU pinouts.
For info, where did you get your 3k stally from? _________________

Just some thoughts that have been passing through my head, i thought i would share the info here.
Most of the speed cut controllers for the aristo work by disengaging(sp) the traction control system in some way, now i know that most of them dont do this all the time, that is that once they hit say 179km/hr the traction control system is disengaged thus removing your speed cut. However under said 179km/hr your traction control would still be active.
Now if this is the case it would be extremely simple to build your own "speed cut defender". The aristo uses a electronic speedo so getting a signal wire from that would be relativly simple, all you would need to do is measure the voltage (im assuming its controlled via voltage altho it could work off varying resistance at certain speeds) at said 179km/hr and build a cercuit whos output is disigned for 12volts up until it reaches said speed where it would output a 0v signal to a relay on the supply power side of the traction control system (where the fuse is) hence opening the contacts of the relay and causing power to be removed from the system, which would have the same effect as someone pulling the fuse.
Maybe sometime in the future when i have some spare time i will build one of these "speed cut defenders" _________________

i just removed the trc fuse under the bonnett and did over 200k/ph and still going.I was beside my mate doing 250k/ph before i backed off.Its the best.

The other way, to maintain your TRC electrics, would be to find the line that runs to the TRC butterfly in front of the throttle, and put your relay on that, so as you come close to 180, the trc wants to shut it, but you force feed it 0V and leave it open.
The good thing about that over the fuse-pulling is that if somethin goes wrong you can back off and trc will come back alive. _________________

Well the only time your are going to need to do these kinds of speeds are on the track or the drags so why not just take out the fuse when u go down then put it back on for street driving? _________________
