When TQ managment jumps in it doenst fall on its face. It pulls a few degrees timing.

You can feel the timing being pulled but it doenst feel like active handing or traction control shutting down fuel flow. The AH/T-control you are talking about is a complete shutdown of the air/fuel flow and is not what TQ management is nor is it what is being asked about. Disabling this with the console button doesnt remove TQ management.

I can turn it off with HPtuners and back on again...over and over and you can tell the difference.

 

Interesting that Charlie at A & A tuned mine with both HP tune and LS2 edit and didn't observe what you are saying. In fact no read me file jumped out from the raw computer only what the tuner sofeware presented. In fact Hp went up when timing was reduced from the 26 degrees that LS2 edit allowed to 16 degrees as per HP tune and the ping went away. Of course timing will be affected with different load and rpm conditions but not this sinister plot of GM to save a transmission maybe to save a piston. Of course if I would have stayed at a Holiday Inn Express I might be able to understand better.

 

As reader of this thread assess the credibility of the engineering-challenged members claims that TM is a myth, please read the following...from the tuner Jimman claims told him TM doesn't exist.

A&A Corvette's CF advertisement

We have just upgraded to the newest Dyno Jet 224 X with eddy current load cell. Only a true load cell allows the tuner to hold the vehicle at any load and throttle setting for a predetermined amount of time. This, in turn, allows us to analyze each end every "fuel trim cell" for proper fueling. The standard 248 DynoJet with a "brake" simply can't do this. It can only add load by dragging the brake to slow the run down in order to gather more data. Not the same thing. I did a lot of research before investing in this particular dyno and determined that this model would be the best available unit for tuning, not just measuring horsepower and torque. I've also just invested in a module to log boost and fuel pressure as we tune. This gives us more needed information to tune supercharged cars properly. With the latest versions of LS1 Edit, LS2 Edit, HP Tuners, EFI Live, Ease and GM's Tech 2 editing and diagnostic software, we have the capability to tune your LS1, LS6 and LS2 powered vehicle for optimum power and driveability. Fuel and spark curves as well as torque management and transmission settings are optimized for your combination of performance modifications. We also have the capability to tune more radical vehicles in "Speed Density" to enhance driveability dramatically. We are the only shop on the West Coast to have all this in our tuning "arsenal" Please call or e mail for appointments and information.

So they told you TM doesn't exist, but their own advertisement say is does. Who are we to believe, you or our own eyes?

Enough of the spinners and game players. This is deceipt, plain and simple.

My tuner told me he tuned out a large percentage of TM. He used HP tuner. I really know very little about it, but my A6 definitely hesitates on the launch. My 60 times are slower than my C5. I have not run it since the tune, might go to the track tonight if it dry's up around here.

 

I'm not the one who is saying that TM causes it to "fall on it's face". I'm simply responding to those who say their car is falling on it's face and blaming it on TM. Honestly, I think most of them are not turning Active Handling and Traction Control off.

 

with the A4 and torque converter management.

 

That is also my experience. I have 90 rwhp more in my C6Z than my C5Zs; but the C6Z is no faster in the 60' and 330'. The reason is TM.

shurite44, you may want to visit your tuner again and further tweak the TM and related values.

I'm stuck with TM until satifying myself I've found the bottom of my ETs with the car bone stock.

is the ls6 used in four wheel drive vehicles, i understand the ls2 is.

doesn't the tuning software allow you to 'edit' a variety of vehicles ? not all functions in the software apply to all vehicles.

how can one trigger a tm event. would it be possible to use your launch technique to cause a tm event. does it feel like a slight miss or is it just a very slight hesitation ?

if we could identify the sensors or how it's monitoring the 'system' would we be able to interupt the 'signal' and therefore disable tm ?

 

This is why you cant tell if it happens because you don't know how to activate it. it has been stated many times the better the traction the slower the 60 ft. and 330 and even if you drive around it and pickup your 60 ft. you don't get similar1/4 mile gains of better et.as you would with a none TM. car pick up 1/10 60 ft get 2/10 et. when you heat tires take off at Maximum power and traction TM activates have someone stand behind car and they will hear it on and off throttle sound in the exhaust note.when car spins it doesn't activate so if you cant drive. you cant activate it or feel it auto or stick you will feel it in the shift to depending where you shift at. of course you have less torque at redline.you guys with autos heat your tires floor it off the line you wont spin the stock tires slow 60 ft times drive off easy roll into throttle faster 60 ft times try it I cant believe people give you pointers to faster times and the reason why and you dought us we are trying to help everyone go fast so you represent corvette well I am tired ofpeople saying the are dogs because you guys cant drive

 

using this argument i would need to have faster times than someone else in order to prove my point ?

 

So let me see how this works. Sitting at the line in a 3200 lb car with NO wheel spin allowed, launch at say 2000 rpms which means car should move at around 15 mph. So the car will instantly reach 15 mph or will the engine rpm back off to meet that new 0 mph speed for a moment. So is this TM, that instant of clutch engagement when engine wants 15mph and car is at 0 and GM is worried that the transmission might break and a warranty claim will ensue. I think I would want timing to be pulled so as not to get pre-ignition and punch a hole in a piston that is in the wrong place at that moment in time. Or do we just go for the gusto and advance the hell out of it because Bubba and Billy bob are on break from Wal-Mart’s door duty and will tune your car. Sorry just couldn’t resist.

 

Do you know his contact info. I would like him to tune my car as well, but can't seem to find his # anywhere.

 

look on DC corvettes

 

no i don't think your driving technique activates it. you know how some drivers can relay info to there crew chief of what the car is doing. the rest of the story you know.

 

Hey Ranger, .

Well I have not been back to the track since the tune. Hopefully tonight.

I will not be able to tell precisely where my gains will come from though. I added quite a few bolt ons this weekend. I gained around 45-50 HP on their dyno.

Similar TM type scenario happened to me when I went with wider sticky tires on my A4 C5. Hesitated enough that my racing buddy asked me what happened when he saw me launch. I have a suspicion that the auto has more TM programing than the M6 but who knows. The guys with HP tuner seem to have a handle on it though, I will find out tonight I hope. I should be able to cut a 1.8 60 with my setup I think, I hope anyway. My C5 ran a 12.71 with a 1.83 sixty foot (CAI, cat back, Hypertech tune), I sure hope I can beat that with my C6 with LG pros, high flow cats, corsa sport, vararam, and a dyno tune.

 

Lets just see have you ever raced your c6 at any track and what are your times.do you have any goals of going faster or racing any more.if yes we would like to hear them. if no why do you care about TM.

 

Hey Gary how did the rims work out did you try them on the car yet

 

if that's what it will take, then fine, i'll bite.

i just got my car back from the shop. had the clutch replaced, my vehicle was covered under the 6k high rpm shift tsb.

now that i have the 'new' clutch i'll take it out and see what i can do for you.

 

Tuners handle edits to TM in various ways, because there are muliple tables with TM impact, but the impact of changes is not linear. This is because the various algorithms themselves, which draw upon values in many different tables, are not precisely understood, since they are embedded in proprietary firmware.

So there is some experimentation involved for the tuner. And you may benefit from an ongoing dialog with your ECM tuner as you start making passes in your C6. On-board data logging at the track would be best. That data combined with your slips and some hand-held weather station input would be ideal.

Rob thats the only way to no. good luck but if you want just think all 06 c6 have better 60ft times after GM changed out the back rear and all 05 c6 have a slower 60ft because GM put less TM in the 06 because it had a stronger rear.
