Velocity Adjustable Throttle Booster System

Iam seeking some contact with anyone that can lead me to get info about the Velocity Adjustable Throttle Booster System.

This sounds like a device to overcome the terrible delay our cars have on the throttle. The sprint booster works well over the stock motor, but it is not enough.

While driving there are many times that Iam firewalled and WAITING for the engine to start opening the throttle.

If you can direct me , I want one if it is available to test and use.

Thanks for any assistance, Woody

 

heres the email for jbspeed who has this unit for sale

i sent you a link for this unit and can resend it if you need it

Wow....$400.00 !!! Someone 'really' values thier R&D...

 

Didn't the Carlsson SLK 32AMG race car have an old school throttle cable? I can find a pic if we need, but I am pretty sure it did. To me that would be the simplest answer. No cruise control, but complete control over the throttle (no learning or resets either) would be GREAT! You also would not have to worry about buying SprintBooster or Velocity or other electronic gizmo. I would think for $400 you could put a throttle linkage and manual gas pedal on the car. Thoughts?

The more I learn about newer computerized cars, the more I hate them - when it comes to modifing! For a stock daily driver they are great! However, having to try to circumvent all of the electronics to make a good car great and fun to drive - by knowledgable drivers is a pain in the ****! Unless there is a Bowtie or Blue Oval on the engine and associated electronics it is very difficult indeed.

Anyway, back on topic, if you gutted/removed the motors/gears on the TB, but left the sensors (TPS) intact, could it not work as a manual TB with a linkage hooked up? If you did it right you might even be able to return it back to stock if you ever wanted to.

Good luck Woody!!!

Calls made, waiting for the response. It installs like the throttle booser "sprint".

We'll see, if it is good, Ill have it running soon and report back to ya.

 

I've been thinking about that too, I wish I knew more about how all the stuff in our car actually works though.. I've been having trouble finding technical information on how the electronics work and interact. Anybody have any good websites or anything?

 

and you guys thought the "sprint booster" was expensive....you pay to play....and yes, I miss my old "throttle linkage"...glad the ole' Harley isn't fly by wire....good luck Woody....you ole' inventor you...

 

This does nothing more than take the signal coming in and multiply it just like a Sprint Booster, only difference is this has the ability to adjust the "gain" or turn it off completely. This will fix your slow throttle problems just as much as the original Sprint Booster fixed them.

I'd personally say F this and wait a few months to see if anything better has hit the market... Hint Hint. But don't ask me because my lips are sealed.

 

oh Rudy, I like what I see you lucky dog you...can't you take the lag out now with a tune....????

 

Without going into specifics, it is possible to make fly-by-wire as fast as a cable throttlebody but through a tune, not to the best of my knowledge.

 

Sounds as though you have something up your sleeve, other than just your arm.
So now we wait!

 

my sentiments exactly

 

The problem here is that without extensive research in to how the stock ECU handles errors it would be impossible to know if this would work. The last thing you want is for the ECU to go in to limp mode because the TB is ~10% from where the ECU thinks it should be.For example, say you have the throttle 20% down and the TB is 20% open. Then, you go WOT and the throttle cable instantly whips the Tb 100% of the way open, but your ECU is looking for it to be at 20% still (while it is processing the inputs). Because the ECU is expecting a 20% input, but it is seeing a 100% input, the ECU may go to limp mode.Another possible issue here is if the stock Tb isn't a 1:1 ratio. Say there is some economy programmed in and at 50% throttle stock the ECU only opens the Tb 35%. Well, when you go with a cable and are at 50% throttle your Tb is at 50%, 15% away from the target. Again, this could cause limp mode.These are just a few possible hiccups you will most likely encounter if you try to turn the electronic throttle body in to a mechanical one.The "best" case situation would involve an actual stand alone system that interaces with the OEM ECU to not only control the Tb but to please the ECU at the same time.

 

HDDP ended up putting a Motec600 on his race car - eliminating any ECU hiccups and ALL ECU nannies. That would be the way to go! Anyone want to loan my $4500 for the upgrade?

I didn't think about the "economy" standards programed into the ECU like you mentioned or just a lag in the ECU when trying to keep up with a manual TB. I guess in the grand scheme of things $250-$400 for a quicker throttle response is not bad compared to the R&D it would take to re-engineer the car.

It's not bad IF you are actually increasing the opening speed of the TB. Something that simply sends more voltage sooner to the ECU to tell the ECU to open the TB is silly. If you want more sensitive throttle teach yourself to push the pedal down a little further!The thing that is discouraging about those modules is they still won't work to speed up the Tb when you go WOT, as they can only output as much voltage as the accelerator pedal. To me, the only time you really need the Tb to open quicker is at WOT.

 

I can tell you that I go to the firewall during autocrossing and the ecu is holding me back almost a second at times. I have disabled the yaw sensor with a switch which assists the controller to not limit the power in hard corners.

If I had a true throttle cable Id gain more than 10% (reduction in track time). THis is my quest and the reason for the search. Woody

 

We're all on the same page buddy.

 

Ive sent many emails to crazymomo1028@gmail.com and not gotten crisp answers. No conformation that it will work. No information that they have sold it to a crossfire.
No gurantee it will fit or money back
No gurantee that they offer.
I was told to send paypal to the email above ????????? Is this a company or not????????? Iam spooked about sending money without more concrete information and or solid backing.................

Woody and wary.

I want it and dont know how to get there?????????

 

Waldig, did you ever get to try one of these units aitocrossing?
