Guest stinkinpoor Posted June 13, 2009 Share Posted June 13, 2009 hi there, quite new to the supra thing so I have no idea if this is common, but... when attempting to accelerate to top speed, the car seems to run in to some kind of limit at about 120ish. It seems to be a a rev limit though because as soon as it gets there the car backs right off. The car is a stock j-spec tt auto. The only mods being a 3" bore cat back exhaust and an air filter. I purchased it like this. The box was set to o/d on and manual off. Could it be a faulty speed sensor causing this. As I have a spare to replace with. Thanks p.s tried search but couldn't come up with anything similar. Quote Link to comment Share on other sites More sharing options...

gordy07 Posted June 13, 2009 Share Posted June 13, 2009 Possibly still limited Quote Link to comment Share on other sites More sharing options...
rob wild Posted June 13, 2009 Share Posted June 13, 2009 Yeah sounds like the 112MPH speed limiter Search for top speed delimiters Quote Link to comment Share on other sites More sharing options...
Guest stinkinpoor Posted June 13, 2009 Share Posted June 13, 2009 it seemed to reach its rev limit, would this happen i its still limited? was hoping that would be what it was though. Faulty speed sensor wouldn't cause any of the above then, just for the od light to flash on and off (annoying). thanks though will check it out.

hogmaw Posted June 13, 2009 Share Posted June 13, 2009 What revs were you at when doing 120? I think that is around the limit of 3rd gear. Or you could have hit fuel cut, but unlikely if not decat, so maybe your car is still limited. You can get an electronic box which will delimit the car and then you'll be able to get much higher speeds. Quote Link to comment Share on other sites More sharing options...
Guest stinkinpoor Posted June 13, 2009 Share Posted June 13, 2009 it kind of revved to the limit then bounced back i was expecting it to change up :-s Quote Link to comment Share on other sites More sharing options...
hogmaw Posted June 13, 2009 Share Posted June 13, 2009 Are you sure o/d is on? If it's off then you will stay in 3rd and that's your problem. Quote Link to comment Share on other sites More sharing options...
Guest stinkinpoor Posted June 13, 2009 Share Posted June 13, 2009 o/d is definitely on but as the sensor is malfunctioning and flashing o/d off in the display omtermitently maybe this could have an effect? Quote Link to comment Share on other sites More sharing options...
