Difference between the vitesse and COW is that you can remove the vitesse throttle controller and sell it when the time comes.

 

Can you change the sensitivity of the COW booster on the fly like you can on the Vitesse?

 

Nope!

 

I have definitely decided on the Vitesse since it is easy to adjust. Just considering CoW for the tune.

 

. I guess that is possible but from the way other members speak of their experience with Chuck I hoping he would be happy to do a tune, without trying to push his booster product, if that is all that is requested. I guess I'll find out. Thanks.

 

A handheld tuner, such as Diablosport, is for the same reason (self adjust) and even though it's a taste higher cost, you can put your car back to bone stock when you sell it and sell the tuner separately. I only suggest this as an alternate to a good dyno tune, because maximum power is not your priority, but the ability to create the driving experience to suit your style is what you desire. Used ones may be available in the C6 Parts forum.

 

Great choice!!

 

Anyone can get a Diablosport inTune plus a custom tune from Lew for $495.00. The Trinity is somewhat higher if you want its capabilities. It's all done with emails once you get the tuner in hand. I am extremely happy with his tune for my A6 and the Vitesse, as it turns out, is the frosting on the cake.

Most people that get his custom tune are very satisfied with the results.

 

I was planing on the email AutoCal with CoW, no dyno tune. I assume the handheld AutoCal can be reversed as well, or not? I would not be able to tune the car myself, but would rely on the expertise of a professional. Thanks for the heads up on the parts forum!

 

Thanks for the info. I am considering this route as well. So, you had your tune done first and added the Vitesse after? No problems/changes with the tune? I see others here say it would not change anything, but I just want to hear from someone who has done it this way. I'm searching for the right order ( if there is one) to do the mods. Thanks.

 

I've had a built and tuned engine for several years before I added the Vitesse. It had no ill effects on my tune whatsoever and only enhanced my driving experience.

 

I just installed mine today, for previously owned 2 diff vettes with sprint booster, i can says that this thing is LIGHTYEARS better than anything else!!! Even eco mode works awesome! EVERY single vettes should have this its a must!! You dont know your vette till you have this !!!

 

Timmy,

Would you share what you feel the differences are between the Vitesse and the Sprint Booster?

 

I have had Lew's custom tune for several months. I was concerned the Vitesse might react adversely to the custom tune, but just the opposite occurred. With the stock tune, you had to press the accelerator a good amount before anything noticeable would happen. With Lew's tune, you only had to press the accelerator less than half the distance as stock. With the Vitesse, SP0 has become Lew's tune. With the increase of the SP settings, you can adjust the feel to your liking, which is SP6 for me.

I'll bet this thing even makes a stock car drive like a completely different car. You definitely will have a smile on your face.

 

Thanks!

 

You can. Chuck can program different throttle sensitivity into the computer, then you as the user choose them by going from regular mode, traction control off, and competitive mode.

Tom you can log throttle blade position and pedal position with HP Tuners and see what the difference is for various pedal positions with the unit. You'll be able to see different curves on your scanner, blade vs. pedal.

I've had a COW booster for years now and it really works as described here for making the car feel a lot more peppy. And it's great for heel and toe throttle blips which is why I got it. I'm sure this device works the same and as noted has a greater range of adjustability. By the way my Prius has three modes based on different button sets as well, and I understand the C7 has different throttle maps based on different active handling settings as well so this way to modify how the car feels is becoming very common.

Subfloor and I are having some good conversations about his new C7Z06...the relationship between the pedal and the throttle blade is absolutely NOT direct and completely different from a c6. You hit the pedal and the computer decides what to do with the blade and it's not anywhere near linear, you should see his scans.

I spoke to Howard at Redline about this the other day, he told me that the new controllers base throttle openings on a polynomial calculation - pedal input is a "suggestion" to the computer, and it gives what it thinks it should give based on available traction, torque limits, etc. etc. It's a huge difference between pedal input and throttle blade when you see a scan.

For old guys like me, I said this sounds like a Quadrajet with it's air valves on the secondaries - the secondary throttle blades are mechanical, but the air valves control the air and fuel admitted to the engine, it only draws as much as it needs (based on the spring wrap you set if you know that little secret). It also reminds me how at 12 years old I could ride my buddy's tiller engine mini bike a lot faster than he could...because I knew how to use my finger to bypass the governor on a B&S engine to give WOT. I told Subfloor too bad he couldn't run a string from the throttle blade in his car to the interior like I ended up doing on the minibike. lol

 

I'm curious. Does something like this have an effect on a manual C6?

If I want more power I just step on the gas pedal harder and leave it (or shift to) in a lower gear.

Car seems to respond pretty well.

 

It makes a huge difference.

Here's a write up I did years ago wherein I tried to explain it. It's easy to feel but somewhat hard to explain to someone who hasn't felt it.

One thing is for sure, everyone on this thread raving about how much of a difference it makes are not making it up, you'd never get that many people to create false recommendations...this isn't Yelp you know....

Sorry Joe, but the key words in my question were "on the fly." The Vitesse has 17 different setting that you can scroll through while you are driving down the road. If you are going to use your comparison of regular mode, traction control off and competitive mode, you could use these three different modes in each one of the 17 settings.

So the real answer to my question is, no you can not.

This Vitesse throttle controller is comparable to a BMW throttle controller called a PedalBox.

 

What are you talking about? You asked can you change settings on the fly. You can change from three settings on the fly. Not 17 of course but three.

So the real answer is yes, you can.

Now this Vitesse is a lot easier to install that removing your computer and sending it in (I did it when Chuck was in the same town) so there's other benefits to this, but to answer your question, yes you can change on the fly.
