Vitesse question

[tbss1]

I would like to know how the professional tuners feel about this product. Not trying to start anything, I Just feel if you get a good tune that this thing would be of no use. But if they (professional tuners) feel that this is something that is worth putting on a good tuned car I will definitely buy one.

No professional is going say anything but buy my tune it's better than VTC, there have been countless post from guys that are tuned and still get the benefit from using the VTC

Only time were the VTC does not live up to exceptions is when you have ported TB with intake, the VTC still functions as advertised but the throttle response is already greatly improved from the intake and ported TB so it neglects the throttle improvement achieved by the VTC

Is your car tuned with Vitesse? If so did you feel any difference?

[tbss1]

Is this thing the same as sprint boosters?

[tbss1]

I think I'm going to try this out. For the price. If anyone has one they want to sell, let me know have paypal ready.

I installed this in my camaro which has a hypertech tune and it was a great throttle response. I like it

I wonder how it would be with the 4.10 gears.

Tuners can't modify the potentiometer sensors signal built into the accelerator pedal which is what controls the signal going to the throttle body to determines how much or little to open the throttle. Whereas the VTC control unit can modify (ie. boost the sensor signals) going to the throttle body based on the SP settings.

Prod tuners correct me if I'm wrong, but I expect to hear crickets.

You are 100% correct tuners can't tune throttle response on the E38 ecu, they can decrease TM that will give a improvement to throttle response through allowing more power not to be limited by TM . that's why VTC is still used by guys that are tuned because it controls the part of the car that is unachievable to modify with the ecu

Yes I'm tuned with the VTC, the tune only optimizes the AFR TO 12.5 TO 1 on wot and optimizes the ignition timing so there is no knock (predetonation) plus adds a few degrees of timing here and there but mostly just efficiency. The reduction of TM will let the power come through with out the spark or fuel being cut off to limit the power. I did feel a difference from both but not the same feel .the tune gave more power the VTC gave more response

[davidscamaro]

Those two feelings are easily mistaken for each other because the end result "feels" similar. I choose to have both because why not I personally like the fact I can control another part of my car

Thanks, you answered what I was wondering, ill be ordering one.
So if I get more bolt on that need to be retuned, I won't have to uninstall the Vitesse to retune my car, right? I get my tunes through email, no one on island has a dino, that's why I ask.

Nope you never have to touch it again ,the tuner won't even know it's there unless you tell him
