Guys

I've lost the instructions for adjusting my yellowbox. I'm running 4.77 gears and standard 16" wheels/SO2JZ tyres.

I have done a search and found that other members have found the difference to be 13% but I don't know how to put that into the yellowbox.

Can anybody help?

Thanks

 

Goto http://www.ricks2k.com/ and you will find instructions in there under yellow box

 

go out and do your own timing that is in the instructions so that you can adjust it to your own specs and not that of someone else. every speedo is a bit different.
