Is this Secondary Main VE Table only on the 99-00 trucks? I'm trying to do a VE tune and I think the secondary table is seriously throwing it off because the LTFTs keep going up even when I raise the Main VE #s. I DL'ed some tunes from 01-03 trucks and they didn't have this table at all. How do I work around it? Or do I just copy the main numbers into it? Please help

 

just switch to an 02 operating system. that's what I did and it's very easy if someone like me can do it. Just copy all your old stuff from your 99-00 OS

 

Did you have to pay $100 for a new license?

 

yes you will need a 2001-2002 bin license to switch to a 2001-2002 PCM
(service number 12200411) use the 2002 file, just copy all your 99-2002 tables exept the v.e of course. Also be sure to turn off the dtc for the terminal L

 

Just copy the corrosponding lines to the 2nd VE table from the main VE table.

 

That's what I did. It kinda sux having to fill in the blanks (the secondary table goes by 10's, the main by 5's. It took a lot of extra time but I got it nailed down. The truck seems to have a better exhaust sound or it might just be my imagination. Thanks for the tips, but I'm gonna stick with my 2000 VCM for now.

 

Not with efi live I didn't. It wasn't a big deal at all.

EDIT- You should only need a new liscence if you switch pcm's.
