Still nice to have my stock read as known "truth data".That read you took is really for Woolich benefit, not yours. Its how they harvest unknown ECUs from the field. You read it and then if they don't already have it in the library its sent off to Australia to be deciphered.
If you restore your ECU to stock, you'll get the stock bin file that is already in the Woolich library.
With regard to the TC vs WC table, its never worked as anticipated.
By never worked as anticipated do you mean doesn't work at all?
