ive been lookin at the racelogic system on the supra sites, its a absolute must of the 600 brake + supras, the key to it though is the mapping of it, if its fitted 100% spot on it will still work like a bog-o-shite if its not been set up properly, there are a few people who have gone to great lengths developing software maps for it on the supras to make it work well. i supose the same will be true for a cossie, its not just a matter of fit and forget, it does need quite a lot of small tweaks to get it to be spot on
