ran several tunes and all is well-but i noticed that the tables b8034,b7902,3,4 all are out of range
so i tried to adjust and they wont go over the max limit-so i said forget it and loaded the tune-well the truck died
i limped it home and read the codes -then checked the history and the tables that i tried to adjust said i changed the values from numbers way above the efi limits even though i didnt change them
this is on a 2008 sierra 1500 l98 auto with the e38ecm
sorry for being unclear -will fix my sig

I'm still confused about this post.
Here's what I show on a 2008 Truck calibration -

{B8034} Estimated MAP Maximum 105.000000 kPa
{B7902} Low Baro Threshold 75.000000 kPa
{B7903} Med Baro Threshold 84.000000 kPa
{B7904} High Baro Threshold 94.000000 kPa

Are you saying all your values were set to maximum?

Cheers,
Ross

no,all the values are set at 29 psi-actually thats what it SAYS theyre set at but the actual values are different-
if i try to change them it wont let me go above 29 because thats the efi limit

ok, now I think I get it, as you can see I was looking at them in metric and they looked fine. I'll check it out.

Cheers,
