Solution: Speedo calibration, details inside Options

[snapshotgt]

It looks like my speedo is reading on the high side. I am using the e153 tranny out of a 99 Solara. I also have bilstein struts, tein springs and 7th gen GTS wheels with 205/50/16 tires.

Four sources of evidence of possibly reading high:

1.) GPS is reading ~10mph slower

2.) OBDII reader from the solara is reading ~5mph slower

3.) I can be crawling at a snails pace and it reads obviously high

4.) When slowing down to a stop, needle can make un-flowing drops down in speed, does not look very accurate.



Please post your thoughts and suggestions. I'm looking to fix this and get it as accurate as possible. Anyone running with a e153 tranny swap please post your experience. Thanks-

Thanks for the post corey - i see i'm not alone.

Isn't there some type of electronic gadget i can buy for about $50-$100 that fixes it? I remember reading a post a LONG time ago about that... ?

Many people have also said just take the needle off (VERY CAREFULLY) and put it back on correctly... ?! I've got an extra cluster so i could practice.

Not sure how well this would work as it's a progressive problem - the faster you go the more it's off [if it's related to tire size etc.]

I guess i'm just not totally sold on it being a progressive problem. Even when i'm sitting still it reads high (2-5mph) ...but this may just compound the issue. Last i checked w/gps i was reading ~10mph high while going 40 & then 80 (thus, not progressive). I just need to do some more testing.

If that is truly the case then you're needle is probably just installed wrong or been moved [possibly by the swapper?]. Try you're other cluster and see if that clears it up.
