I've searched on it. In one post Glenn tried it and said his speedo still registered incorrectly, but Diacom worked fine. A few months later, Traxion mentioned a link to Dave Zug's site where it was outlined how to adjust VSS for gearing. (https://www.thirdgen.org/techbb2/sho...threadid=39272) Zug's link is dead.

Anyone have an updated link or info? I'd like to change from 3.27 to 3.73 and need to know so I can order drive and driven gears if I need em.

 

While I see the need for adapter code if you have a 40,000 pulse tranny (T56), I would think that it minimizes the need for "extra stuff to go wrong" if you just gear it (your 700) for the 3.73's.

My understanding of the higher pulse rates is that it was necessary for ABS & Traction assist, not for the ECM...

I guess I'd rather have "standard code that works" over custom stuff that works, if there is no benefit. I had read Zugs article also.
