Predator tune, new cal id needed, changed gear ratios

hasman70 · Post by **hasman70** » Mon Jul 23, 2012 1:06 am

I have a 2010 Suburban, have in and out at the stealership for a couple of months now, they updated pcm with new calibration, and installed a new torque converter for a trans shudder condition. Predator now shows no tunes available other than modify stock tune and backup, two ecm communication codes come up. Need the latest and greatest tunes. I have been running a modified mpg booster tune for about the last year with good results, however HATED the gear ratio (3.08 and have just changed to 3.73.) I also am wondering if I can use this tool to set up the correct pinion factor (speedometer calibration) so that it reads correctly. Thanks. Cal Id's that come up are 12636005 main os, 12650895 system 12650880 fuel system 12631610 Speedometer

What is the software version at the top of the main screen of the tool once powered up?

UGHHH, What's the story on a tune? Do you need more info? Are you on top of it?? I'm taking a 2k mile trip starting next weekend.....I'd like to get it set up and use the program before I take off to avoid issues if possible. Thanks!

Seems to have loaded on the vehicle, do you have the mpg booster file that will work on this version? Thanks

All is well, except, MPG booster tune not showing up, options are diablotune, 87 octane tune, modify stock tune, original backup. Thanks

what engine do you have in your suburban?? do you have DOD/AFM on it?? if not, then you will not have the MPG Booster tune, since that tune is only for AFM/DOD trucks....

Burban is a 2010, 5.3L with DOD setup. Prior to having it updated by the dealer, the MPG tune is what I was using. I'm leaving on a long trip Friday and would like to get it back to where it was before it was reprogrammed if possible. If not, Lew, I will definately be contacting you for help with a tune when I get back. I was going to use the trip to get the trims figured out. Is there as much of a benefit to modify the Diablo or 87 tune to get better fuel economy? The other thing that has been changed after the dealer swapping out a bad torque converter and reprogram was that I installed 3.73 gears front and rear because the 3.08's were horrible. Still can't figure out why GM would lug the crap out of this engine in stock form. I'm hoping that the fuel economy will improve along with having much better driveability. I'll know in about a week I guess... Thanks
