Sprint Booster Module

Hi all,

just tested out this module that's plug and play to to the electronics at the pedal. It makes the initial throttle response from steady state really rapid. Has anybody tried it before?

Was tempted but never heard of it before so was thinking of asking around before getting it.

Searched the net and apparently its german company called AMB tuning. I translated the contents. Comments, experiences?

Cheers

Chiptuning and nevertheless we do not have better responsing mode, higher torque and achievement in the lower speed range and reached more than with Chiptuning
Already starting from 950 Umin the torque already begins.
Sprint booster - better responsing mode of the elekronischen accelerotor pedal

In the last years we got very many calls and inquiries, from drivers, who are dissatisfied with your vehicles.

One of the most frequent questions was placed us is:
What for possibilities gives it, in order to obtain a better passage?

On our demand which for vehicles they drive, got we usually the answer:
It concerns Benziner with 1,0 litres up to 1.8 litres of motorizing. Further we stated that it always turns around the same weak points. Usually a new vehicle bought with same series achievement as an identically constructed older vehicle or a similar model, but with the following crucial disadvantages:
High consumption
very weak responsing mode
Passage equal zero

Not comparably with the old models
Vehicle does not react at the accelerotor pedal (fuel intake)
Pedal must be nearly always depressed

Due to this frequent very similar question we have begun also smaller engines to optimize around more achievement to obtain, so that the drivers have the desired fun with your new vehicle.

Unfortunately only an increase in output from ca.8% -16% is to be obtained to by exclusive optimization with new vehicles with electronic accelerotor pedal and suction engines (engines without loading). Considering the weight of a vehicle this unfortunately too little is to be made lucky around a modern driver. Therefore we concerned with it, who possibilities there could be of changing with a vehicle the responsing mode and the passage, have to place ourselves in order the driver again contently.

Our result: The Sprint booster

It is an electronic module, which is installed simply between accelerotor pedal and plug.
Thus a new computation is made by the potentiometer, which is in the module. and thus all delays at the accelerotor pedal are eliminated.

The modules are accurately adapted to the respective motor vehicle types.

The assembly duration amounts to between 5-30 min. (depending upon motor vehicle type).

Further additional advantages

Acceleration also at low number of revolutions
Passage in the whole speed range
Sprit save up to 16%
No unnecessary load of the engine
one has to have the feeling 15 HP more
Exhaust gas values remain series values
No attitude necessary
No interference in electronics

Disadvantages:

None

As we determined for the small motorizing the very much brought credit we begun also for the vehicles with larger capacity to develop
 
I don't see how they recon they can speed it up its just a potentiomer on the pedal with a resistance from it being used by the ECU to calculate throttle openeing requested.

Well, I'm not a electrical engineer but 2 ways to possibly do it.

1. if the software takes some time (quite negligible) to calculate and convert the potentiometer readings into electrical signals, is it possible that this card (size of a PCMCIA card) helps speed up this process?

2. More likely, it just boosts the signal from the potentiometer and requests for more opening from the throttle then wat was previously requested for?

Unfortunatly not
1) The ECU just reads resistance its does in instantily the throttle body is the slow bit of the proccess.
2) That will just tell the ecu that you want more throttle all the time just like sticking your foot down a bit more all the time there no less lag just more power always been asked.

It could work like brake assist. Brake assist looks at the rate of application of the brake pedal and when it sees you pushing hard on the pedal it doesn't wait for you to get the pedal pressed all the way down, it anticipates it, and jumps straight to maximum effort, leaving the ABS to ensure the brakes don't lock. This could do the same with the throttle. When it sees you pushing the accelerator hard it jumps straight to maximum throttle - telling the ECU to open the throttle body air flap all the way as fast as the stepper motor on it can - without waiting for you to get the pedal pressed all the way to the floor. If it did that the engine would go to maximum power quicker, and the car would accelerate quicker sooner.

The other possibility is that it does A-to-D (analog to digital) conversions on the accelerator potentiometer more often. The ECU can't read it continuously. It might read it every half a second. If this unit read it every 10th of a second it would notice more quickly (by a couple of tenths of a second) that you had pressed the throttle down and tell the ECU to open the throttle sooner, again effectively giving you faster acceleration from the time you pressed the pedal down.

Both these are what in computing are called "latency". The delay from the commencement of action to the result occurring. Reducing latency has the same effect as increasing power without using any more fual or putting any more strain on drivetrain components or the laws of physics.

On the other hand what it might just do is increase subjective throttle response by giving you more throttle opening when the accelerator pedal is only opened a small amount. That would make the car very jerky and hard to drive smoothly. Which is exactly why ECU programmers slow down the initial throttle response.
