Is the throttle response faster or is it just pushing the pedal MORE than you actually are doing it? LIke you push 1/10th and it inputs 5/10ths instead?
It's not THAT sensitive. It's on the order of 30% I'd guess.
I certainly don't dispute the claims that this device improves throttle "feel" around town and makes the car feel more responsive to a given acceleration pedal input. However, I'm having some trouble understanding the graph you quoted above.
The Y-axis is ETC Output in volts which makes sense. However, the X-axis is confusing. Is it Elapsed time in seconds, or does it represent throttle input via your acceleration pedal (per green dotted lines)?
I found this description on the website:
http://www.sprintboostersales.com/whyitworks.cfmHow It Works
Sprint Booster modifies the signal between the accelerator pedal module and the electronic throttle body. This modified signal forces the throttle body to open 'more' than the stock signal at a given pedal position. In effect, the idle-to-full-throttle pedal travel is reduced. This makes your car 'feel' more powerful because a given pedal input produces greater throttle opening. This is especially evident in the low to mid rpm range where most cars spend their time on the street.
If I'm understanding this correctly, this unit is increasing throttle sensitivity by effectively reducing the pedal travel by making the ETC voltage output larger for a given pedal input. If this is the case I can definitely see how it could improve feel and responsiveness around town. Especially for an automatic transmission where (as I understand it) the ETC voltage inputs are used to decide when to downshift etc.
However, I can also see that for someone using a car on the track, this effective reduction in idle-to-full-throttle pedal travel "could" make it a little more difficult to modulate the throttle inputs.
