I've had really bad experience with my sprint booster !! it locked my throttle wide open twice and i was about to having really bad accident !!!
i lost control on the middle of busy street and i didn't know why my car is acting like that. second time it locked my throttle wide open on the highway, i was accelerating crazy without pushing the pedal !!!! i will call them tomorrow.
i had it for 3 months and it was good.now it is kind a scary !!!!

guys i would go for the DBW from FD, since sprint booster or pedalbox eventhough seems very good deal, but then we have instances like what happened with you. I was still debating weather i should get sprintbooster or pedalbox.

Now have to wait until i head something about pedalbox as well.

BTW @babakweber how did you know it was the sprintbooster and not the throttle itself?

There has been instances where people have reported the same thing even when they have no sprintbooster or pedalbox installed.

For right now i would say uninstall the SB asap.

Safe driving man..

that says it all.. SB is the culprit. But then again the problem is also the throttle as well maybe SB triggered it to be in that state.

Whatever the case. I think you should completely remove it and drive safely. If you really want to eliminate that throttle response I think its wise to go with FD DBW module.


I turned the sb off while was accelerating on the highway and everything back to normal !

What is the difference between SB and FD DBW ?

So SB is nothing but signal booster that you sent out to from the throttle when you press it. It enchances the signal by 25 to 30% and in some case even up to 40%. Which means is the car think you have pressed the gas pedal far enough but in reality you have just lightly step on it.

As for DBW it basically helps accomplish vehicle propulsion by means of an electronic throttle without any cables from the accelerator pedal to the throttle valve of the engine. In simple words its just not a booster to modify pedal sensitivity.

You can check FD DBW at this link.

I just read it. I really can't tell what the difference is...... :(

Guys one is just a signal booster so it does nothing except boosting the signal your throttle response sends out. For example half pedal down might relay to 75% pedal down, so the car will pick up more quickly.

Where as DBW does all of it and more but it does not do it by boosting the signal. It achieves it by tuning and programming control settings.

If you want to understand more about SprintBooster Here is a link

http://www.crosslake.net/~dbipes/sprintbooster/SprintBooster.pdf

Its Conclusion is

Conclusions
The Sprint Booster is a simple amplifier that multiplies the accelerator pedal
sensor signal, making the accelerator pedal more sensitive. It does not eliminate
any significant delay in throttle response, nor does it greatly improve acceleration
figures. It does not change the adaptive throttle control programming of
electronic throttle control vehicles. It does change pedal “feel”. This change in
feel is interpreted by some as improved throttle response, acceleration, and a
change in adaptive throttle control programming. Considering what it actually
does, it is expensive.

Hi Flamgwicky

I understand what a sprint booster is and what it does. What I don't know is exactly how FD DBW is different from it. I read the site which uses a lot of automotive terms saying it is specifically designed for each car. But Sprint Booster and Pedalbox also say the same thing and also say they are different from other booster or DBW system.
How and where is the FD DBW installed? Is it also connected to the gas pedal?

Well yes it is connected to the gas pedal in the same way, but it does not boost the signal as SB or PB does. The lag is still there since SB or PB does not tune or reprogram the response. The throttle response control is untouched in the case of SB or PB.

Where as when you install DBW module it touches the throttle control programming which in todays cars are electronic.

do not play with this guys, it can be dangerous. I was almost going to order my box but I prefer to have a little acceleration lag than going on a wall on the freeway. Few of us already mentioned a pedal stuck and this on made me thing that the lad is nothing compared to a big hit...just my 2 cents guys but do not think is worth the risk

I have read threads with forum members complaining their Ghibli with gas pedal stuck, with engine overheated, with brake issues, with power steering issue, with front differential issue. I think we should all get rid of our cars..... do not play with this...

@yxc145... you would be the last person i expected would say something about returning the cars. BTW were you being sarcastic if so i didnt catch that...

Flamingwicky, you know me well. I was only joking.
Still like the car. but patience is wearing off... as I am dropping off the car at the dealer tonight, the 13th visit in 6 months. No major problem, but way too many little issues. sigh...

@yxc145, so i did a bit of more research and found out that the Ghibli already has a DBW module instead of the old mechanical stuff for the throttle. When we say DBW it means its electronically controlled.

Having said the the DBW from FD is basically and enhancement module that optimizes the programming of the throttle control in Ghibli. Which means better gear shifting and more precise power when needed. Also the lag is there but design in the Ghibli, the DBW enhancement module basically programs is much better to eliminate that lag. Again keeping in mind i am talking about Throttle lag and not turbo lag.

Where as Sprint Booster just enhances the output so the car jumps and accelerates at a touch on the pedal.


I think the forum members not so familiar with DBW may understand it better now.

Problem may be with Ghibli itself!

Folks,

I have not had any throttle issues after I installed the Sprint Booster probably because I have only driven the Ghibli on warmer days since (one or two) the holidays.

Back in June when I first bought the car the gas pedal got stuck and I pulled it back with my foot while on the highway. Then, again in September. I went and applied velcro to my floor mats because it felt like the mats could have been stuck causing the pedal to stay engaged even when I backed off, but now I feel that was not the culprit.

I remember my wife distinctly asking me what was wrong, and why was I playing around in our neighborhood. I shrugged it off so as not to alarm her, but my internal stress meter was on high at that point.

So, my conclusion based solely on my own experience, and after reading several posts here and other places is that the pedal mechanism in the Ghibli is prone to malfunction.
