So for a given increase in pedal position, the sprint booster yields a larger increase in voltage compared to when stock. The sprint booster increases the rate of change of voltage vs pedal position. So clearly the only thing that the sprint booster can influence is the accelerator pedal position that the ECU receives. The only interface a sprint booster has to the ECU is via the accelerator pedal position input. A typical arrangement is shown in the schematic below.Ī sprint booster sits between the accelerator pedal position transducer and accelerator pedal position input as depicted in the schematic below. The engine management system measures the voltage and thus knows the position of the accelerator pedal. Pushing the pedal harder yields a higher voltage. The voltage tracks the position of the accelerator pedal via the accelerator pedal transducer. What does the Sprint Booster do to the Throttle Signal?Ī fly by wire throttle is simply a voltage signal. So before deciding on throwing your money at a sprint booster (or anything else), you should first identify what those negative effects are, to see if the overall response matches what you’re actually trying to achieve. We can safely assume that a sprint booster must have some negative impact. Offering some benefit almost always results in some negative effect. Usually after market accessories simply shift from one compromise to another. Design CompromiseĪs with all after market accessories, it’s good to start from a skeptical position. I’m certain that the manufacturers themselves understand how their own product works. This article is consistent with technical information provided by sprint booster manufacturers. an excellent experiment that you will see in the references section belowĪnecdotal evidence from people who have tried sprint boosters does not invalidate this article.understanding of general process control and engineering.understanding of how throttle by wire works.information provided by sprint booster manufactures.However this article is mostly objective analysis based on the following: I’ve used a sprint booster and so have experienced what it does to throttle response. How do they work and do they really enhance performance?
Claimed benefits include faster engine response, elimination of throttle delay, better performance and the ability to unleash the true potential of the engine. It takes the signal from the pedal and outputs a modified signal to the engine management. Now onto the original article:Ī sprint booster, also called wind booster, pedal box, idrive, throttle controller, pivot controller, electronic throttle controller, e-drive, plug n go module, pedal commander or throttle re-mapper, is a device that intercepts the signal between the accelerator pedal and the engine management on a fly by wire throttle. I’ll do a detailed review when I get a chance. I’ve since removed the device from my vehicle, it wasn’t suited to how I like to drive and how I use my vehicle. Using it has confirmed everything in this article. It’s taken me over a year but I’ve finally given it a try. Why You Shouldn’t Support Mandatory VaccinationsĢ018 Update: Thanks to Kelli from for sending me a free sprint booster to test.
