Speed Question.

[civ_sik]

Hey guys, girls.

my speedo is sowing the wrong speed... 20kms over what i am actually going...
Can i fix this or would it be best to let an autoelectican handle fixing this?

thanks :wave:

how do ya know its showing 20km/h over what your actually doing??

does the needle start at 20 instead of 0??
if it is just take out the dash, gauges etc and reposition the needle to start form 0..

auto electrician would fix it... ~100-150 depending on whose doin the work and the warranty period...

[civ_sik]

i know its 20 over cause my mate was in front going 50 and my car said it was doing 70 and yes it does start up on 15km when im idling, but when theres no key in the ignition it goes back to 0...? :S

Might be a wrong voltage bias being introduced somewhere, if this is what the guages go by. I'm not sure. Maybe a faulty sensor, a short in a wire. Best get it checked out by an auto elec.

Have you got wheels/tyres that are wider and larger than stock. This may also cause speedo to be out, if the new tyre/wheel size isn't in the same ratio comparison to the stock size.

yea i got 17s which would contribute slightly but my mate has 17s too and his car was showing 50 and mine was showing 70 and i was sitting on his tail (both si hatchs) so i dunno, but when its not moving just idling it says im going 18km/h so thats my main problem atm ...

[asiansquad]

maybe ur mates car came stock with 17's??

[civ_sik]

no its an si same as mine

i would take it to an auto elect to get it sorted out. would be a hassle to drive and always look at the speedo and deduct 20kms from it constantly. good luck bro

and yes it does start up on 15km when im idling, but when theres no key in the ignition it goes back to 0...? :S

Sounds like it could be a problem with your instrument cluster. or VSS (does your trip meter click over when you are idling?)

[civ_sik]

na everything is fine except it the speed display is wrong evrything else in working fine...

[civ_sik]

should also point out this is my original cluster, i hadnt had it in my car as i had an eg6 one in it but it fuked up, so i only put it back in and intantly it was doing the wrong speed thing...

[civ_sik]

okay car went to auto electrican yesterday, got it back today and its all good.

thanks for your help y0 :thumbsup:

[Eclipsor]

they say what the problem was?

[civ_sik]

didnt ask man lol im not like that hey as long as it works its sweet

[Bowzer]

you didnt have reverse indigo gauges installed into the cluster have you? installing those things can upset the calibration of the speedo... in some cases you have to replace it
