speedo recalibation?
can the early classic scoobs be recalibrated.
mine is miles out, when using 215/40/17 tyres, at 70mph (gps speed) the car is doing around 81mph (clock speed) i dont mind 3mph or so out. but over 10mph is silly any where that does it? |
any ideas how to get this done
|
Place across from Trent bridge house will tell u, just before Brooks toyota, those little shops that stand back( sorry cant remember the name of them)
|
thanks mate. i'll check them out
|
anywhere else?

Could you have gone for the wrong profile? I did not see (vodka glasses) if it was under or over. If it is reading under then the rolling circumference is to small soi you need a larger aspect ratio ie; 45's or 50's. If it is reading over then the rolling circumference is too large so you need t go to a smaller aspect ratiop ie 35's or even 30's. I have seen convertors online somewhere, so try a google search as that might help if you put in the standardt yre details then the new wheel size. If you or a previousowner has changed the wheels.

its reading over, well over. if it was the 3mph then i wouldn't mind. but over 10mph out the converters are good for imports, to convert from kph to mph there must be some way to ajust the speedo? |

Nothing wrong with the tyre size, its only 1.25% out compared to std size. I bet its more to do with something like a gearbox swap, thus the speedo is not matched to the gearbox speedo drive. All IMHO :thumb: |

All IMHO :thumb: with 45's its ok. but the 40's!!!! so i need to get the speedo sorted out the standard wheels on a p1 is 17'' + 45's and thats slightly out. but any smaller and. you get what i've got. miles out |
205/45/17 is the std size for a P1
using a 215/40/17 at 60 it would overread by 1.2mph A mate has a P1 and regardless of the 2 variations of sizes you mention , he has never reported any such issues with the speedo. I reckon its a compatablity issue. I have similar speedo issues and also have a box designed for an electronic pick up and dash, rather than the std speedo cable. I'm not overly bothered as i know its 20mph/1000rpm in 5th so easy to work out, plus its exact to my GPS! |

Yeah I know it fits straight in what im saying is, there may be some variation in the gearing/electronics of later speedos hence the calibration issues.

my car is electronic type.
the uk95 was. i wish mine was only out by 1/3mhp. but at 60, its 9/10mph out i was tempted in trying one of them adapters. as i know the p1 boxes are also fitted to some of the sti's (i checked the box code) but where do you fit these? |
