Also I Know The Engine Spark Retard For Tq Management... And The Abuse Mode In The Trans.... You Said There Were Other Places I Can Change Tq Management.... Is There Any Other Areas I Need To Do?? Im Gonna Go Ahead And Remova All Tq Management....


And Max Tq You Were Talkin About Is On Tq Management Section Right??

Also I Saw Disable For Tcc Says I Believe 100 % Tps, Or 100 Mph So Is Taht Bad If I Pass 100 Mph It Will Unlock The Converter?

One More For Now.... Why Are There 3 Settings For Speed Limiter?? Can They All Be Set For Same Speed?

 

OH YEAH... AND WHERE DO I FIND THE A/F RATIO FOR REGULAR PART THROTTLE DRIVING?

 

yeah that a/f was a little lean. Mike told me that 12.8-13.0 is great for our trucks so that's what I went with. As far as the spark stuff goes, in the top of the window there's a box where you can multiply selected cells by a certain amount. I'll post more later when I'm back from school.

THANKS ALOT GUYS

 

That is in the Engine > General > Air Fuel Ratio > Stoich AFR....But you don't need to mess with that any, it is set to 14.681 from the factory which is where it needs to be.

 

I would also zero out the Torque Loss % table and the Traction Control method stuff. If you want to get rid of TM while in tow/haul mode you will need to modify those table too.

Also under the ETC limits I would raise the ETC TPS Max Table to all 100 and zero out the ETC injector disable.

In the Engine TM section there is also an abuse tab that I would look at with three parameters, Max out the first and zero the next two.

Thats what I can think of off the top of my head.

Yes the TM section under the engine section.

No that is not bad. If you are in WOT with those setting it will already be unlocked anyway. You may be able to pick up a few MPH in the 1/4 by locking it earlier, but it is harder on the transmission so I would just leave it alone.
There are some changes you can make to the TCC duty cycle, but I'm not sure if they are needed or help any with a stock TC.

Not sure why there are 3 settings, may just be some sort of redundancy. I would just set them all to whatever you want.

 

your VE tables are going to effect your daily part throttle a/f ratio calculations. As for my fueling tables they are pretty damn good for a stock tune to be honest. There could be some improvements, but all I really want to focus on is WOT right now. If you look at the dyno truck list you can see how smooth the curve is and the a/f line is nice too. Not bragging, just sayin that the stock VE tables are workin quite well for me so far.

I think if you started tuning some spark in there you'd be pretty satisfied. I felt a little improvement in the pants dyno lol. Tuning spark is pretty straight forward too. Add until you get KR and then back off. You don't want to go too extreme though.
There was a thread recently in the eng&exh perf. thread I believe that a few fellas were arguing about what kind of timing to run. I think my max commanded in my spark tables is 25 or 26. You'll notice when logging that if you add the PID's for IAT adder and AFR adder to the scanner you can see how much is getting pulled for IAT's and how much is added from afr advance tables. I was boggled when my commanded advance was around 29* sometimes, but then I noticed that the table was really commanding 26 and the afr adder was 2.5* or somethin like that.
sorry to ramble again. I'm down at the beach house by myself goin nuts cuz there's nothing to do. too cold to fish, and I would do some tuning myself but I left my cable at the house

 

ok guys i still dunno where to go to do my adjustments.. i wanna start adding 10% timing but im not sure which table

is it ENGINE<SPARK CONTROL<(MAINSPARKADVANCE) LOW OCTANE??

IF SO... WHAT ELSE WILL I HAVE TO CHANGE TO MAKE SURE THAT IS THE ACTUAL COMMANDED SPARK ADVANCE?

HERES MY NEW TUNE... I THINK I REMOVED ALL TQ MANAGEMENT... PLEASE TELL ME IF I MISSED ANYTHING.. I ALSO CORRECTED THE PE EQ TO WHAT YOU SUGGESTED. I THINK I GOT EVERYTHING... THE ONLY THING I HAVENT DONE IS RAISED THE SPEED LIMITER OR SPARK ADVANCE AS I WANNA SEE WHAT TABLE IT IS FIRST AND WHAT OTHER TABLES WILL NEED TO BE DONE

ALSO ATTATCHED 2 LOGS... NAMES TELL YOU WHICH LOG IS WHICH

 

You will want to up both the High and Low Octane Spark tables. The High Octane table is the main table the pcm uses and the Low table is what it blends to if it detects KR. Unless you have the truck in open loop then it only used the low octane table. A straight percentage increase may help a little but pay attention to the cells you hit most while driving and at WOT. I would up the ones used in the WOT area more than everywhere else in the table and then smooth around them. Do some logging and make sure you aren't getting a bunch of KR. Make sure you are happy with your fueling before you get too crazy with the spark tables and read through one of the guides for spark tuning I think there is one in the stickies here and I'm sure there is one on the HPT forums.

There are several different places that affect spark based on ECT, IAT and some other things, most of those I wouldn't do much with. I would zero out the Base AFR Correction table and maybe reduce the Base IAT Spark table some.

You still have some TM on in the Performance table (Tow/Haul) in the Trans section and there is some in the engine section under Maximum Torque >> vs. RPM table. You could probably leave that one alone though since it is only in effect while the TCC is locked. Also in that same area there is a Traction Control section, I zeroed out the Retard vs. RPM table, not sure if that table really has any effect on the trucks, but I zeroed it anyway.

I will have to look at you logs a bit later, I figure I better get at least a little work done today... Maybe Wheatly or Zippy will stop in here and give you some pointers also or at least warn you if I tell you something stupid..

 

no worries... thanks alot for your help ryan... gonna go upload the tune right now and will log
