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-

in terms of removing your needle, when i removed mine i turned the key to on and THEN put the needle right on zero. that worked for me, GPS-tested and everything. (if you decide to go that route man)

Mine was way off when i did this.
My solution was to drive around as steady as possible and by using the GPS speed see how off my speedo was. Stoped refit the needle and try again until i got it right. If you need to refit the needle before the rest pin... plug it in slightly, bend it a bit to pass the rest pin and you are good to go. Within a few minutes you will be able to get it spot on.

P.S Be very carefull when you remove the needle inorder not to break it and do all adjustments while you are safetly parked and with the key to ON.
