That thing just adjusts the voltage output of the stock accelerator pedal sensor, such that say a small movement of the accelerator pedal can now cause a larger voltage to be applied to the ECU input and hence cause a larger throttle plate movement for a smaller accelerator pedal input change.

This will certainly give you the impression that the car has more power or acceleration, but the simple fact is its not going to produce any more power or torque than if you just were more aggressive with the standard setup.

The ecu has say a 0 to 5v input and this is interpreted as the accelerator pedal movement say 0v is no throttle and 5v is full throttle. Your device can adjust the rate of change of this voltage, but putting more volts than 5v onto this input of the ECU achieved nothing as the ecu has already interpreted it as 100% throttle application at 5v so feeding 6v or 8v into it achieves nil.

you can achieve the same result by adjusting the throttle tables in the ecu code, but again you produce NO extra power or torque. your just adjusting the "feel" of the throttle pedal to make it more or less aggressive.

for the cost of that device you could likely get a proper ecutek or oft or other tune and actually achieve power and torque increases, by actually changing the ignition timing, fueling, intake and exhaust cam timing.

If you want one of those throttle controllers then buy one but the claims are false and misleading.

steve99: it's as you wrote on all accounts of how it works and what provides, what not .. but still, that 'feel good' bit, that some testing it reported. - Yes, it won't bring more power, but seems that those that tried, prefer throttle opening curve with this to that of OEM .. so at very least imho this might be worthwile mod to try to implement with OFT, alongside other existing mods, like cold start, economy mods and such. Just like clutch pedal bite point adjustment or short throw shifters, it may enhance enjoyment of driving and imho worth experimenting with, even if there is no actual performance improvement except subjective feel. But it's fun we are after in these cars, no? :)

This item is ideal for all those people that have leased their car. They don't want to do anything permanent, yet they want more power. So, for all those out there who want more power, but want it easily returnable to stock for lease return or dealer service, here is the product for you. It doesn't say anything about mileage though, so count on your city mileage going down.

I drove my car today with the sprint booster. It is the best modification I've ever done. The difference is much bigger in comparison to a similar modification in the FB20 engine. The FA20 engine has much more potential! Overall, my car is now very different in the mid-low range with much more torque. I am very happy with the change. I definitely suggest this modification.

Reminds me of back-in-the-day when some folks would drill out the jets in a carburetor.

Yes, that would let more gas into the intake manifold, but, without changing the cam, all that it did was ....... burn more gas ....... car didn't go any faster ......:popcorn:

:lol: I've re jet a carb on a friends car and bear in mind how young we are I dropped the float needle and lost it somewhere underneath the car, it wasn't a good day after that.

a cheap (free) easy alternative to this is to just push the gas pedal further... come on now, are you guys afraid of going past that halfway mark on the pedal?
