Speedometer / Odometer Calibration Solved!

[biomax]

Sorry. Just have to share this with everyone. It's the little things that make me excited.

Due to my 33" tires, my speedo was off ~13%. I ordered a ratio adapter from Commercial Speedometer Service in Sacramento, CA. It took <5 minutes to install, and now everything is accurate (per my GPS). For more info and pics, see my build thread here.

Can you get correction for various gear ratios and tire sizes?

 

[biomax]

Yes. Somewhat. There are certain percentages they can offer. I don't know what all they are, but give him a call. He's very helpful. Just know your current % off is, and he can tell you what is available.

brilliant. by any chance do you have an email address for him ?

 

[biomax]

Nope. They don't have email or a web page. Just the phone number. It's a small speedometer shop in Sacramento.

Would you have the # handy? I sure would like to do this to my FJ.

Thanks,

Link was in my first post. Copied here for those click-disabled.

So Tuesday, I ordered a Ratio Adapter (P/N 800F 1.1555) from CSS (Commercial Speedometer Service) in Sacramento, CA.

Greg Burlin was my contact (916.371.5873) and shipped me out the adapter same day. Because I'm in Nor Cal, I got it next day via UPS.

Total cost? $69 plus tax and shipping = $85.48.

Speedometer Service in Portland ,OR also makes the conversion gear boxes. I had one on my recently (last night) sold FJ60. When I changed gearing again I called them up and they just sent the gears to replace to correct the speedo and it was spot on both times.
