Let's kick this off with a 10 people Group Buy for the price of $420 shipped.

VELOCITY brings forward the sheer excitement of driving, by improving and optimizing the throttle response, enabling up to 30% of improved throttle response. Installation of Velocity is simply by ?plug and play? to the throttle pedal connection, without any modifications to the car. Upon installation, the unit is powered up by the ?SPORT? button. Velocity offers 4 modes of selection and users can vary the throttle response simply by selecting the ?+? or ?-? button on the control pedal.

Velocity utilizes proprietary, intelligent and self-learning feedback algorithm that monitors the car?s sensors and optimizing the injection mapping of the Electronic Control Unit (ECU). The unit then automatically calculates the fuel injection amount and timings required, according to the various power modes and altering the car?s response tremendously according to the desired selection.

Another unique feature (first of its kind) of Velocity is that it allows users to switch between ?Original Profile? or ?Sports Profile?. The unit has a built in function that allows users to switch off the sports profile if they want to drive the car in normal mode, or switch on if they want to have increased throttle response, simply by the touch of a button!

Technical Specs
- 4 power profiles selection (MIN, MEDIUM, MAX1, MAX2), adjustable according to different driving needs.
- Optimized throttle characteristics to enable immediate throttle response to the engine in real-time, resulting in faster response.
- Simple ?plug-and-play?, with no modifications.
- Slim and compact design.
- Unit can be powered off during driving, and powered up as needed, anytime.
- Intelligent, self learning feedback algorithm to enable optimized driving throughout the power band.

You guys gonna do installs? :whistle:

Basically its the same thing as a sprint booster? Hmmm

Thats a bad ass steering wheel, lmao...So besides the fact that you can change the settings, it's pretty much an adjustable sprint booster? :think:

Is there only one Velocity for all E60 models regardless of automatic or manual transmission? Also, it would be nice to confirm which of the 4 power profiles selection (MIN, MEDIUM, MAX1, MAX2) is most comparable to the current Sprint Booster? Reading the other threads is seems like people say it is either MEDIUM or MAX1, and depends on the car, but not sure if I read that correctly..

If I can get somebody to buy my SB to offset the price of the Velocity, I might be in...

nice steering wheel :devil: ... where did you get them and how much? I want it.. :evil:

Does this mean that the Velocity unit actually alters the stock ECU's programming with relation to fuel injection and timing? This scares me. The SB simply alters the signal for the drive-by-wire throttle to shorten the delay but it doesn't mess with fuel injection and timing, as far as I know.

My guess is that the Velocity unit does the same thing as the SB but whoever wrote the above just wanted to sound more technical. :lol: '

Can someone elaborate? For those who has aftermarket software like me, I don't think they'll want any other adjustments to fuel and timing.

Yes, 1 velocity for both manual and automatic. Max 1 is equivalent to aggressive version of SB, Medium is equivalent to standard SB.

Max 2 has the highest punch, more powerful than the SB.

Velocity read and self learn to adapt.

SB does not read signals that is coming in.

Velocity doesn?t mess up the fuel injection and timing. The connection is purely into the pedal and not ECU, therefore there is no overwriting into ECUs.

sooooo.. is anyone going to commit to this GB? :whistle: i'm interested, but one of those guys that usually sign up as #8 or #9 on a GB..

does this work for the c63 amg? and are u honouring that price shipped for canadians too?
