#Sprint power booster install#

I highly recommend this device, and once you install one on your Smart, you will also recommend one to other owners too.

Before, going up a hill in third gear required a significant amount of pedal input to get the transmission to shift down into second, but now that same task only requires about ¼ throttle input and the transmission kicks down into the lower gear with very little lag time. The most noticeable change that happened is when I’m climbing a hill. Additionally, because of the aforementioned performance changes, the car performs like it’s had an additional 5 to 6 H.P. The Sprint Power Booster adds additional voltage to that signal which eliminates 99% of the throttle response lag that occurs when you push the accelerator pedal down.Įven though the device does not change or re-flash the engine management computer, since it’s installation the car responds better, shifts quicker, and it takes much less throttle pedal input to get the car moving from a dead stop.

The butterfly in the throttle body opens and closes with an electronic servo that picks up a low voltage signal from the throttle pedal. I just had Smart Madness install a Sprint Power Booster in my car, and I wanted to tell anyone who might be interested that it really, truly, woke the car’s performance up!! :smartje:įor those who may not be aware, the Smart car uses throttle by wire instead of a traditional throttle cable from the pedal to the throttle body. I've had my Smart since early February and I love it.
