Milage Helper Maybe

[jwth]

I don't normally condone something like this since there always seems to be an ass bite back
Since the Gas prices are up and so is everything else
I am sharing a HP TUNERS template from my 5.3 l 2003 Yukon that has been running around 24mpg hwy and 20 or so city
USE AT YOUR OWN RISK
USE AT YOUR OWN RISK
This has been running on my 2003 5.3l 4x4 Yukon SLT for over 90k miles with no issues
You do need access to HP TUNERS
Yes it will get me "OH NO'S" form many, but I use it and have saved $$$ driving this brick 140 miles a day for work

RENAME THE FILE TO MILAGE.HTT before using it, It is a hpt template

If ya don't like it no problems, keep the snide to yourself and go be peaceful someplace else

Mind sharing what you've done with it? I don't have HP tuners. Curious if I can emulate anything w/ my diablo unit

 

[jwth]

sure
smoothed out the VE table and increased it for performance
increased the timing tables by at least 7 degrees and more at 1000 to 4000 rpm ranges, some more or less depending on vehicle performance
pulled back on the knock retard tables and adders, still active just selected ranges
adjusted injector flow rates and adders
adjusted the throttle tip in and acceleration rates
adjusted the transmission for a more comfortable ride and softer shifting

more but I have to look it over to tell you o.l.d. disease ya know

should be a good starting point, every car is different.

could serve as an outline for the 6 litres

2003 to 2006 for sure,,might apply to others

I have hptuners that I needed for a trans swap so I have everything I need to try this out. Thank you so much for posting this!

glad to help
let me know if there is a problem, I had to rename the file to upload it and I hope it will work after renaming. I seemed ok on my end.

24mpg is pretty sweet; I felt pretty cool at 18mpg lol. I wish I currently had a tuner set up to try it.

with some tweaking of the timing table I was able to run at 26 mpg, did for awile but backed it down when the local gas mixture changed, spark knock on acceleration, using the 87 octane fuel.
