Unfortunately for Japan, they can't use their cruise control over 112 km/h. I live in the UK and own a 4.0 V8 Soarer, or SC400. At 70 Mph, the engine hardly warms up, so normally I drive a bit faster, got the restriction removed, it's great! But the cc doesn't engage at speeds higher than 70. I've seen some really blurry, out of focus pictures on the internet, how to change this. Does anyone has some better pictures or a more detailed description of how to fix this? Thanks!
