Default The dragstrip without torque management...

made it up to great lakes tonight. My previous best was:

R/T .027
60 1.87
330 5.162
1/8 7.822
mph 93.82
1000 10.084
1/4 11.991
mph 118.76

My best 3 times tonight were:

R/T .259
60 1.882
330 5.082
1/8 7.684
mph 95.20
1000 9.911
1/4 11.790
mph 120.12

R/T .162
60 1.899
330 5.100
1/8 7.703
mph 95.12
1000 9.932
1/4 11.812
mph 120.08

R/T .125
60 1.898
330 5.106
1/8 7.708
mph 95.12
1000 9.937
1/4 11.816
mph 120.38

My conclusion: Removal of TM gave me 2 tenths, and possibly more if I had drag radials. I was spinning in my 1-2 and 2-3 shifts alot more than before I removed it. There was virtually no improvement in my 60'....I truly believe that it is my tires, and my inexperience, that is holding the car back in the 60'. Not really convinced it is TM. I'm also convinced that with DRs, I can acheive the magical 11.49....where I would get kicked off anyway.

I was getting alot of comments and people walking up to me asking if I was supercharged, what my mods were, etc...people weren't used to seeing a regular C6 putting up times like that. That part was really fun.

BTW - the weather was very similar...in fact, it was warmer tonight and more humid than on the night I got my previous best.

I have a 2006 A6 F55. Mods that matter are: LPE stage II heads, a modest 224/230 XER comp cam, 3:15, LPE intake, melrose headers, ported FAST intake. This was on stock runflats with 14k miles & 7/32 tread left on them, 62 degree night (10 degrees warmer than the night of my previous best time).

Congrats on a new best! How were you launching your car last night? Did you roll into it than floor it or brake torque it and stand on it?

I've always brake torqued it. The track was so empty last night, I should have tried a bunch of different launching techniques.

nice very consistent. its hard to tell if its tm. your 60 fts are worse yet et better. i always go better on a worse 60 ft it never adds right since it was warmer the runflats will work better. but you spun more on shifts yet your 1/8 mph is higher

Yeah, trying to make sense of the slips can make you crazy.

But, I think here if I take a step back, it makes more sense. The problem off the line is mostly my tires (and me, of course). Probably not so much a TM thing...getting DR in the future will improve that greatly. The elimination of TM - I'm telling you, it's dramatic. The car THROWS you into the next gear...and you get expected spin as a result. If you had stickier tires, there's energy in the 1-2 and 2-3 shifts being wasted in spin that could be captured. The spin was not evident at all with TM enabled on my 2-3 shift, and only half as much in my 1-2 shift. So, despite losing some energy in increased spinning, my trap speeds were higher and time was better. The combination of better times, plus the SOTP meter that's telling you the car is an animal, supports that TM is costing at least a couple tenths...maybe even 3 or 4 even if you use DR.

The car definitely got faster as the air cooled down. My trap speeds were 118 and change when I first got there, with 75 degree air. My 11.79 sec run was when the air was about 62 degrees.

the traction on shifts. the spin makes less tm faster times. drag radials make more tm. more spin equals better 60 ft and times

I'm not sure I understand what you're saying. To me it seems that more spin = slower times. If you hook up and get all your power to the ground (no spin), you'll accelerate faster. Right?

you should but with TM cars you dont. you still dont see great 60 fts even with nitrous on the starting line. everyone i know with just a little spin on the starting line produced the best et. guys have put drs on with know improvement in et or 60 ft. you will probably see improvement with drs with h&c. the thing with tm when you hook up you will see better 1/8 mile et mph and slower 1/4 et and mph. you have to learn how to drive around it

I still dont get it. 'm trying to understand you, but I'm getting more confused.

Can you please be more detailed in your explanation, including what TM is doing and what it is causing? It seems like you're saying that cars with TM dont spin their tires, but dont get good 60' times. But, cars with TM DO spin their tires...just not as much.

your comment of "the thing with tm when you hook up you will see better 1/8 mile et mph and slower 1/4 et and mph. you have to learn how to drive around it" is totally confusing to me. Are you saying that TM cars will have worse 60' times, BETTER 1/8 TIMES, and worse 1/4 times??? That doesn't make sense. And I have no idea what you are talking about when you say "learn to drive around it".

I'm not being sarcastic, just trying to understand you, but your posts are too cryptic.

Let me try to restate what you are saying, and you can correct me if I'm wrong...

You are saying that cars with TM in their programming see slower 60' times

I'm with greentank. I'm not understanding your comments. He removed TM, so why does he need to learn to drive around it? He is saying that by deleting TM, he is getting more power and more tire spin. With DR's, he may be able to transfer that lost energy to the ground, and get better times. Bottom line, deleting TM seems to be getting more power to the tires with the potential for better times. The problem now lies in how can he keep the tires from spinning to allow him to transfer that power to the ground.

I think what Dennis is saying is that, no matter the tune, TM cannot be completely removed from the programming. TM applies itself during positive traction , not during wheel spin (i.e.the harder you hook, the more torque to the wheels and the higher the percentage of TM applied).During loss of straight line traction, and TC off, there is nothing (nanny wise) to keep your car from accelerating full out.This theory is consistant with both launch and during shifting. The harder the tires hook, from say, the 1-2 shift or the 2-3, the higher the % of TM, even though with tuning it is somewhat relaxed, is still applied. As an example, my first runs in my C6( with 50 less rwhp and torque) is identical to my last runs with the extra hp and tq, with the exception of a much higher MPH ( 117mph to 121mph). Currently the car reads more torque being transfered to the wheels and applies the TM accordingly, even thoug, yes, it has been "tuned" out of the car. Dennis's launch techniques , i.e. driving around TM, has shown great results for him and others who have used it.Some are seeing better times with DRs, of course, but would see even better numbers without TM period, and as of current, that is not possible with the tuning software availible. I know it goes against everything I've ever learned about drag racing, but it is true . Try a bone stock , un tuned car at the track and the TM is so envasive, it almost seems as if the car wants to shut off on a good hooking launch. I hope this both helps educate and further confuses you, as the TM issue has been a pain since day 1 in these cars for me.

I understand that a little better. However, Evilways...have you had TM disabled using the HPT beta version? I had it "disabled" using the older version, and let me tell you....NIGHT AND DAY is the difference. Nothing in the least bit subtle about the change in shifting.

The other thing that is still unclear to me is...what is "driving around TM"? Will you or somebody else please explain what you're talking about regarding this launch technique?

its about going 1.588 60 ft and 11.62 with bolt ons and still 11s with stock runflats and 12.0 with stock runflats, stock gears. stock converter, driving around tm, sometimes less is more

I guess I'll ask one last time.

I'd really like to understand what driving around TM is, and can you please discuss your launch technique.

Are you going to educate a humble and fellow vette driver that wants to improve?
