Trying to do a fuel system segment swap to get my fuel gauge working on my 98 to 99+ pcm swap. Everything seems to be copying over fine, and all tables and parameters are changed back to my 98 info. But the gauge still isn't working, just stays maxed out. Is the problem that I needed to do the segment swap before going with a COS? Do I have to revert back to my original GM OS then segment swap, and then start over on my COS5? Thanks guys!
