Hey I was just wondering if anybody had a start up tune they wouldn't mind sharing with me. The car is gonna be maf less and no 02 sensors and once I have the bugs worked out will be twin turboed . Its a 2001 5.3 with a 4l80e . Im new to gas tuning on efi live but am very familiar with the diesel side so any help or tips are greatly appreciated.

Can you find a 2001 5.3L truch file at www.tunefiledepot.com

if it has the 4L60E segment you can do a trans segment swap from a same-OS-4L80E file (if you can find one)...

or, since you will have to modify the trans subharness anyway (for the 4L60E->4L80E segment swap) you could simply run the 4L80E from the 4L60E segment with the harness relay mod (not requiring the segment swap).

Would you happen to have a link for the harness relay mod. Also do you have any tips on running with no maf or o2s

Running MAF-less (SD) see the AutoVE tutorial, but try to perform Calc.MAFT, see post #1 here:
Calc-MAFT-correcting-VE-and-calculating-MAF-(in-single-log)-gt-reverse-of-Calc-VET (http://forum.efilive.com/showthread.php?16413-Calc-MAFT-correcting-VE-and-calculating-MAF-(in-single-log)-gt-reverse-of-Calc-VET)

Also, before doing that read post #1 of Calc.VET:
Calc-VET-correcting-MAF-and-calculating-VE-(in-single-log) (http://forum.efilive.com/showthread.php?15236-Calc-VET-correcting-MAF-and-calculating-VE-(in-single-log))

After reading those, you should be able to perform AutoVE using WO2BEN instead of the BEN pid (using the calc_pids.txt file from either Calc.VET or Calc.MAFT).


For a better understanding of AutoVE and Calc.MAFT, see post #29 here: Summary-Notes (http://forum.efilive.com/showthread.php?14188-Summary-Notes)

Gasoline engine requires the correct AFR and spark.
