Im very new to efi tuning and ive been trying to soak up as much info as i can. i bought a turbo kit from another member of this forum and he was kind enought to share a tune he had on his truck for me to get base settings. (the tune was actually for a procharged 4.8 becuase hes recovering his hard drive to get the turbo tune).

ill attach a picture of what i think was the proper thing to turn off in hp tuners for deleting evap?

is there anything i need to change for the evap delete?

also if someone could look over the general settings of my base tune to see if im in the general proximity of a startup tune. the truck is a 2001 gmc sierra with a 4.8, single 69mm borg, 2 bar cobalt map sensor, p01 computer, 1000cc injectors.

this forum has been loads of help and i cant wait to start a new build thread.

Thanks guys!

Disabled your cat codes too, and P1441 I think for evap.

The VE is really really fat, probably going to flood itself right away. I'd input the stock VE for 15-105, then build the VE up to 210kpa.

Raise the power enrichment KPA from 55 to like 80-90kpa. Lower the enable torque down to 50% because TM is maxed out. Lower the enable setting for the pedal if you want. Most choose a lower pedal enable and leave the PE/BE up to engine rpm and map KPA to enable that.

Timing curves shouldn't mirror each other, the low octane table should have less timing in case of knock. It will use the knock learn factor to figure out the timing if you see knock. Generally have like 4-5 degrees less timing in it. So if you want to run 14-15 degrees at timing at full throttle, have that same area be 10-11 in the low octane timing. Or just make the whole high octane curve how you want it, copy/paste to the low table and minus 5 from the entire thing.

Thanks for the quick reply FFDP, i appreciate the pointers. im still a couple months out before im done with the build so i should have plenty of time to figure out a decent base tune. as far as the speed density settings do they all check out?
