Hi,

 

Ya so does mine, :)

 

Maybe Toyota decided that above 70MPH you should be paying more attention to the road and doing less "cruising" :D :D

Nah it's just down to where the cruise control get's it's speedo feed. If it's before or after the convertor. You want it to be wired into the same wire as the input signal for the convertor, not after it as it will be as stock, so you need to trace the speedo wire from the C.C. ECU (look at the electronics manual on mkiv.com) and cut it and splice it into the speed signal wire that's going to the convertor.

It should work up to something like 120.

It doesn't matter which delimiter you use, it's down to where the speed signal feed for the cruise control comes from. You want it to come from before the convertor. The Thor unit has a 1:1 output so you can wire it into that, or save yourself the expense of the Thor unit and wire it in before the convertor. 6 and 2x3's.

This Thor diag indicates how theirs is wired with a 5/8 signal - not 1:1 as suggested above.

 

Could someone explain in more detail to what I have to cut or swop about to sort this issue out ?, I have the same problem as above my CC will not go past 70mph

 

Thanks Jamie.

Thor's diagram above looks correct and good to go... if you can't suss it out from that maybe you shouldn't cut wires :p

 

(Honestly not trying to put you down, but I can't think of a better way to explain it than that diagram does :) )

My wife had the speed limiter in her Soarer cruiser control removed. There was a fix on the Soarer owners club site. I have been told by JDM Supra owners here that the CCs in these are limited to 110km. That just doesn't cut it as the drive from Regina to Calgary takes 8 hours and the traffice goes a legal 120 all the way. Do any of you know if the Soarer CC fix will work on the Supra?
