So my boss today let me borrow his otc encore can tool. He says it can be used to reprogram rear gear ratio in vehicles and I can’t figure out how to find that setting for my 1996 gmc k1500. Does anybody else have experience with this tool?

As in, after physically changing gears and then “reprogramming” ECM?
