I have been messing around with this stuff for a while now. Simply it is awesome with my mods, but I was wondering if anyone has any 1999 files they have tuned some with? Or, if you have tuned any year truck what were some of the things you have done?

So far I have 6.0L spark table, little bit firmer shifts with higher shift points and deleted torque management. Also, 160mph speed cut off and 600rpm idle (due to cam and underdrive alternator pulley). Any more ideas???

Thanks,
Ryan

 

I'll send you my 1999 file with Hypertech 93 octane tuning on it. <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />

 

I have a lot of 00 and 02 stock files and some edited files for my 00. Most all of my tinkering has been with trans cal.

btw.. have you compared your HPP3 file with the stock file? +4* timing in one table is all I found as far a engine tunning goes with mine. <img border="0" title="" alt="[Roll Eyes]" src="images/icons/rolleyes.gif" />

 

Hypertech also changed the PE vs RPM multiplier some on mine. I think I saw another change, but its been 10 months since I have looked at it.

 

Wierd! I compared every table on mine and that was the only one I saw a change in. +4 for the 93 tune and +2 for the 87.

 

Alright, thanks BigTex.
Is it just adding +4 to the entire table for 93 octane tuning? When I did 6.0L tuning much of the table was different additions instead of something like a +4 Add Value to the entire table.

Are the Low Octane and High Octane Spark Tables for WOT only or for entire vehicle operation? I think it is entire operation for all condiions, right?

Last quick question, I can only read 1999-2000 truck files with my LS1Edit and cannot read 2001+ files. Can you guys read multiple PCMs?

 

We have 4 truck on our module, 2-2000 and 2-2002 so we can read them all. Your module has to be set to read one or the other or both from carputing.
