jschindler, You lost face, credibility and my respect. Do not hide in words as offended. I'm not offended, I am embarassed to be in the same forum with you. Don't want your kind in my platoon.

But of course, the world must be flat, because the pseudo-engineers continue to "have doubts."
Members can lay out what the Frinking service manual says about Torque Management. Back it up by
(1) the tuning software metrics
(2) GM HiTech Performance article on tuning out TM
(3) countless affirmations by experienced drag racers
(4) many tuners who help owners turn-off TM and achieve improved acceleration.
(5) now the graphics by boosted_Z06
Is that enough evidence....?
Of course not. To them, the world is still flat and will always be flat....Until someone finally produces credible evidence that it's not. They will go to the grave in the dug-in position that TM is a myth.
My last post. When I figure out the technique for driving around TM, I won't be posting it here.

TM has been my obsession in this forum. It is well documented in the threads I started. I understand the frustration all too well. I knew something was afoot on my SECOND PASS.
Now after my tuner did his magic you see a hard pull to 120 MPH and just under 7,000 RPMs.
Hard wheel spin off the line and then HP and torque never drop to negative values until I got off gas pedal so TM exists can can be tuned without turning it off
OK, I agree with you, it does look very odd. How about your second graph that doesn't have any negative torque. Do you have a manual or auto? If it's a manual, are you speed shifting? I would expect with a normal shift you should see some negative torque.
Hey, why are all you guys attacking JSchindler? He's just being inquisitive and he just wants data to show that TM does exist. I'm sorry if I also appear to be a skeptic, it's just that I am also looking for hard data that TM exists. I haven't had my car tuned, so I don't have back to back runs to see what differences there are with TM off. But showing a graph that has negative torque margin is interesting, but all graphs will show negative torque during a granny shift, unless it's an auto or speed shifting a manual. Hey, let's all lighten up a little, we are all after the same thing, trying to figure out how to make our cars go faster. Just because someone questions the proof or data doesn't make them evil! And Ranger, please give us the secrets to going fast, you are my hero! Don't hold back the info.

Glenn - thanks for the support.
Honestly, I can be a bit hard headed, and argumentative. Except for SR0707, I don't have any issues with the way they have shot back at me. I've done the same to them.
I just sent "boosted.." a PM apologizing if I have offended him, and I want to make that public. He has posted good information and done it in a respectful way.
Ranger is my idol. Not only is he probably THE best driver of Corvettes in the country, and far and away the best on the forum, but he has handled himself with nothing but class and dignity.
I'm learning a lot on this thread. I just can't hold back my experiences. I know I can come across as an *******. But I can assure you that most of ya'll would enjoy my company. I'm really a good guy, and as honest as you'll ever meet.

Do your tires spin with a 2000 rpm launch?Do you get wheelspin on the 1-2 shift? With the RA1 you will not. Even the Z06 tires are not sticky. Throw some RA1 or Nitto 555R2 on there and I think you will feel what I am talking about. BTW if you are ever in DFW area come by and we can put my wheels/tires on your car and see if you can feel it.
One tip not mentioned yet where TM kicks in even more on my A6, is while racing over slight bumps on the drag strip WHILE shifting. Need to launch STAIGHT aiming at the FLATTEST surface.

Hey, no problem, I just didn't think you were coming on that strong to get everyone riled up. I respect everyone's opinion on this forum. It's just that I haven't really seen TM.
I had an 01 Z28 with a 224 cam, headers, and a cutout that would run 12.75 at 114 in Phoenix (1250 feet of altitude), so it was quick, but man was that a tricky booger to launch on street tires. Launch at 3500 rpm and the tires would spin, launch at 3000 and it would bog. Some people interpret the bog as TM, but I don't think an 01 Z28 had TM, at least I never read about it over on LS1Tech.com.
Now, I believe there is TM, because otherwise why would the tuners have an option to turn it off? However, I'd like to know when and where it comes into play. Does anyone have a log of a run at the drag strip that shows timing being pulled and throttle position being closed during a run?
Dennis, you took what you referred to as a good natured shot at me yesterday, so let me return the favor. Your C6 has an automatic transmission right? How can you think you know what I'm describing on the TWO C6's with manual transmissions that I've owned? I'm simply relating the experiences I've had with my car compared to what some people are describing.
At least I can say that I now have 10,000 miles of experience with manual transmissions C6's to go by. How about you?
Jim I am not in any way offended just a debate. the reason you cant feel it when you shift because it happens after you shift if you shift a high enough rpm there probably isn't as much torque and it might not set it off but i have road in many stickshifts and drove many in competition. they are very illusional of being a lot faster than what they are so it would be hard to tell. don't get me wrong i love manuals raced them the first twenty years off racing.then when bracket racing got big everyone was going auto so did i. but i can still drive friends manuals faster then they drive there own.i have even taught my daughter to drive a stick in one day better than her racer boyfriend.and now that you have 10,00 miles where is a new time slip to see if you learnedanything with all that seat time in your stick.
There was not one word I used flaming anyone, it is a fact that a stock engine would not have the same TM issues as those of us with 600 HP and assume TM does not play much of a part so it is not intended as a flame but rather TM really is a trip point when engine is at the upper limits GM placed where a stock engine would hit less often the a engine that has performance gains added but still using the same TM limit values.
In other words if GM set the maximum torque to trigger at 350 ft/lbs the engine wtih 600 HP and stock tune would rather easy hit that TM trigger then a stock engine.
In 40 plus years of drag racing I know with stock tires and powershifting it takes around 3 to 4 tenths for the engine to recover from a shift and anyone thinking it takes almost 1 second to move shifter from 1 gear to another needs to time their own shifts and see what it is but in this case let's just say I take 4 tenths and the other 4 is from TM.

We have just as much right to debate this issue as you do.
As to the above acertation. You say it's well known that it takes .4 seconds to shift. Certainly you can agree that a shift can take longer than that, right? I didn't imply that the "ECU has no creditility", I questioned how you can be sure that the time on your chart is not just the time it took to shift. I'm not saying its not so, I'm just saying that there is no proof of it.
Stickier tires? Sure, they can cause an engine to "bog" right?
Don't shift or launch hard enough? Even Ranger admits that its mainly a problem at the drag strip and on drag radials.
Again, let me repeat (because some people insist on questioning my and others stance). I don't dissagree that timing may be pulled under certain "events". But I have launched plenty hard, and shifted extremely hard. What I don't feel - not even remotely - is the "falling on its face" that others report. In fact, I can assure you that my car shifts very hard - there is no softness at all to the hit when I bang the gears.
If it makes ya'll feel any better, I'll go ahead and concede that TM does exist in some form or fashion. Just not what many people say they feel.

Dennis, I have been driving "sticks" for nearly 40 years. I've owned lots of them. I don't want to go into my experience or what I have "learned", as I pretty much regret the comment I made about my shifting earlier on this thread. Shame on me - I should have known better.
I guess I better not even bring up the trophys I won and standings in the AMA national points standings in 1982 for roadracing motorcycles....

Boosted, I liked the graphs you posted earlier. One showed negative torque during shifts, one did not. I would think that if you are granny shifting any manual you will get some negative torque. So were you shifting differently between those two graphs?
Yes manual 6 speed and powershifting but with TM tuned and not kicked in the car pulls much better and nose never drops between shifts.
To me this is all about drag racing, not cruising on the street and the point that TM does add to the ET and causes engne to drop out of it's powerband and that tuning ( not turning off) TM has purpose but does have a effect on stress to drivetrain
At the least if having the horsepower and having to use 4th gear to hit the traps TM adds at least 4 tenths to ET

Both scanner recordings were using the same shift style to show the effects when stock TM settings are used and then when TM is tuned
If you look at the 1st graph as to RPMs you can see it was not slow/easy shifts
