i have a 99 si cluster that i purchased and there is a problem with the spedometer. i mean everything works on the cluster fine but the speed my car is traveling is displayed 10 miles too fast. i was wondering if the spedoemeter is bad or do i need to buy a new one? i searched but i found that no one else had this problem. need help asap. thanks a lot

 

What's your tire size?

 

195/50/15, i know tire size affects speed but 10 mph is a **** load off, so idunno

 

The person that had the gauge before you may of screwed around with it...( replacing the gauge face, removing the dial, etc.... thats if it was used) heres a tip, i did this to mine. remove the cluster and take it apart, put a piece of color tape where the dial lays when the car is at 0 mph, take the dial off then put it back on. i would rec. that you do this and keep testing it while the car is on but not moving; this way, the tach will read exactly where you want it to, and all you have to do is find its right spot. its very tricky and took me a few trys. i have done this both on my rpm and mph tachs. pm me if you have other questions. if your not comfortable with this, you could also just buy a whole new mph tach to replace the broken one.

 

wow i thought i was the only one. i have the exact same problem. the gauge cluster reads 2 mph when off then when i turn the car on it jumps to 29 mph and starts from there. i'm always have to subtract 30 mph to reveal how fast im going. someone help us !!

 

^^^look at my last post

 

yea i didn't really get what you were saying. thx tho

 

ill try psoting pics of the before and after. i may not get to it today, i just pulled 44HR. DAY AND IM GONNA CRASH, but look out for it soon

 

mine is the exact same way.. its off by 10mph.. post back if you get it fixed through JDM_Spec_SI-R way.

 

JDM_Spec_SI-R is right. The person that had that cluster before you might have screwed around with it. I had the same problem with my si cluster. I didn't want to deal with it so i just sold it to another person for really cheap. ( of course i told him before hand that the speedometor was off) .
for the guy who sold it to me without telling me about the problem

 

it's cool man i just appreciate you trying to help us out. i'll definately keep an eye out on this thread

 

yep my si cluset in my 98 is 10 off also. tach is right but speed is not. i am rolling with 195/50/15s too

 

check the speed senser....maybe

 

i would tell you guys to try to take your cluster apart like i had posted on how to earlier, but it is really hard and involves alot of work. i would have to tell you, since some of you have never done it before, not to do it, caus ethen you could ruin the whole cluster. if you guys need some directions and how to's, just pm me and ill be more than happy to help.

 

never had a problem with mine

 

imma have to try takin it apart and fixin the needle
