edd_t Posted September 21, 2005 Share Posted September 21, 2005 Hey ppl, I noticed that I had alot of ppl passing me when ive been going the speed limit! so i got my gf to drive infront of me at 60mph last night. when i was sitting at 60mph there was a noticable difference in speed. i had to go at about 66 to keep up with her. So it looks like my speedo is out, is this something that is easy to fix? Also, my fuel warning light came on last night, how much reserve fuel does the supra hold, its about 8 miles to the closest garage with optimax! Cheers, Edd...

Ian C Posted September 21, 2005 Share Posted September 21, 2005 A J-spec Supra holds 70 litres of fuel. You should have about 12 to 15 litres left when the light comes on. -Ian Link to comment Share on other sites More sharing options...

monkey76364 Posted September 21, 2005 Share Posted September 21, 2005 I look at my angel for an acurate reading ! Link to comment Share on other sites More sharing options...
edd_t Posted September 21, 2005 Author Share Posted September 21, 2005 fair enough, i might go borrow and angel then and see exactly how far out i am. thankyou... Link to comment Share on other sites More sharing options...
tbourner Posted September 21, 2005 Share Posted September 21, 2005 Since fitting bigger wheels mine is actually better!! So that's obviously the answer. Link to comment Share on other sites More sharing options...
edd_t Posted September 21, 2005 Author Share Posted September 21, 2005 the car has bigger wheels. i bought it with a set of 18"s on. the wall hight of the tyres are 40mm. so i guess that will have put the speedo out a bit... Link to comment Share on other sites More sharing options...
tbourner Posted September 21, 2005 Share Posted September 21, 2005 What tyres? 265/30 18? Link to comment Share on other sites More sharing options...
Jake Posted September 21, 2005 Share Posted September 21, 2005 If you change your speedo converter to a Thor Racing one you can adjust it by up to 10% and that will make the speedo read spot-on. Link to comment Share on other sites More sharing options...
edd_t Posted September 21, 2005 Author Share Posted September 21, 2005 ah thanks I'll check out Thor then. and cant quite remember the tyre sizes exactly, only looked at them a couple of times, only had car 2 weeks! im sure there something like 245/40/18 on front, and 265/40/18 on back. but i could be completly wrong!

tbourner Posted September 21, 2005 Share Posted September 21, 2005 Aah, 40% profile, I'd say they're too big then. But wouldn't that make the speedo read low? Link to comment Share on other sites More sharing options...
edd_t Posted September 21, 2005 Author Share Posted September 21, 2005 i got no idea think i best go get it checked out. i've never heard of the company that made the tyres anyway, so there probably some cheap crap put on by the dealer that will pop as soon as they get warm!

Need4Speed Posted September 21, 2005 Share Posted September 21, 2005 Peter Betts' TRL/Thor DSC unit can be fine tuned to fix speedo error... and it does all the other things if you need to sort a J-Spec. Top piece of kit. Link to comment Share on other sites More sharing options...
