    VATS relearn 2002 Tahoe flex fuel tune in 2001 Silverado

    I flashed a 2002 Tahoe flex fuel tune into my 2001 Silverado 1500HD. I of course added the flex fuel sensor and modified the tune for my 6L LQ4. I've tuned everything and it runs great, however I can only start the truck if I disable VATS. I tried the procedure to relink VATS with VATS set to serial in the tune outlined here: https://www.hptuners.com/help/vcm_ed...elink_vats.htm . Both tunes have serial VATS so I think it should work. Any help is appreciated, thanks.

    I was able to get it to work by using the 10 minute key on procedure 3 times, which takes a while. I'm still not sure why the procedure above doesn't work. Thanks.
