can't find a techII how to so as long as you can connect and read the TDCO value you might have to do a KOKO relearn and just use the scanner to verify the results?

Google KOKO relearn.

I don't have a techII so the exact steps are not sometrhing I know but I would expect it to be fairly straight forward when you get into the right menu-just don't exceed 1500 rpm during the relearn adjustment phase.
