dÄHLer ATTC – A power pedal with extra features and app control
Give your ALPINA or BMW a new way of anti-theft protection and at the same time a way better engine response with the dÄHLer Anti-Theft Throttle Commander combined with all Power Pedal features. Controlling of the dÄHLer ATTC via your smartphone is just one of the awesome features of our device.
Anti-Theft System
The revolutionary dAHLer anti theft system comes with an Anti-Theft Mode, a Valet Mode, Power Pedal Mode and is a must have if you want to protect your ALPINA or BMW against theft.
You control your dAHLer Anti-Theft Throttle Commander – ATTC with the included remote control unit without losing sight of the essentials.
How does the ATTC work?
Our module, wiring harness and remote (Anti-Theft System) can be installed in any ALPINA, BMW, BMW M, BMW Plug-in Hybrid and BMW Electric vehicle with an electronic gas pedal and is ready for use immediately after installation.
It’s is a direct plug into the existing (OEM) harness.
The dAHLer Anti-Theft Throttle Commander disables the accelerator pedal on the next vehicle start. This makes it impossible to rev-up the engine without having the dAHLer remote control.
Criminals might be able to crack the signal, open the door, even start the engine and shift in gear, but this is where the story ends. They are unable to move the car.
It is not necessary to activate the Anti-Theft mode again after each stop. The function remains activated by default until the function is deactivated again.
Grand Theft Auto - Is it really that simply to steal a modern car?
Unfortunately, it is absolutely simple, takes 2 minutes with the right technology which is mostly in the hands of criminals.
In vehicles with a keyless go or a similarly functioning system, theft is carried out by means of a relay attack.
Criminals try to intercept signals
It has been known for years that the trick works in front of single-family homes, in parking lots, even while you sit in coffee shop, where there is often only a short distance between the car and the car keys. But underground car parks in large apartment buildings? Yes, perpetrators also run through the stairwells of apartment buildings and try to intercept signals on the apartment doors.
Nationwide in the United States in 2020, there were 810,400 vehicles reported stolen, up from 724,872 in 2019 and that number has increased dramatically in the last two years.
Accelerator pedal tuning
In modern BMW cars when you step on the throttle, you’re not moving a linkage anymore. You’re actually sending a signal to a computer and most of these new BMW have a lot of what is termed dead pedal.
You step on the pedal and it takes one or two inches of travel before anything happens in the vehicle. After the install of the the dAHLer Anti-Theft Throttle Commander ATTC the gas pedal response will improve immediately.
Does it give you any more power?
No, the dAHLer ATTC with Power Pedal features doesn’t give you any more engine power but it makes the vehicle feel a lot more responsive and instead of pushing the gas pedal all the way into the carpet to get maximum engine performance power, you can push the pedal halfway down and your BMW will accelerate like you had it all the way down.
With the dAHLer ATTC device installed there are a lot more responsive and making your car act like a hot rod!
