you can start off by modifying the stock tune.

first keep a copy of the stock tune on a disk and keep it somewhere, and one on the puter and one on another puter. so u can always have the stock tune in there.

do you have your old tuner still?


theres some people who would help out getting you stated with a tune, small changes too about 4 tables is what most tuners do. when using the tuning tool there is a brief description about the table in.

alot of them typically modify tables B0720, B0721, B0727, and B0910.

if by old tuner you mean my quadzilla? yes i still have it but returned it to stock before i started playin with efi. im so confused with all of this. are there like any people who can sit down with u and explain this stuff:argh:

there's e-mail and telephone ;)

is the phone answered on sunday

if im not busy texting lol

Once Danny gets you started he's got a good thread here to help learn some basics of what to start messing with as far as fueling goes. https://www.dieselbombers.com/durama...ly-primer.html :U:

I have 2001 duramax with hypertech set on 70, pulling a 34 5th wheel trailer and I got a check engine lite/lost pulling power. checked the code with the hypertech and it gave me a P0093 code. I can clear it but it comes back within 25 miles. Any Ideals?

a clogged filter can cause that, but the code means there is a large leak in the fuel system.

what was the last time u changed the fuel filter

is there a way to load for comparison two tunes that dont have the same OS #?

hmm, dont know a way if there is.
