No tools. No cutting. No trip to a shop. It connects between your pedal and the factory harness, and it comes off just as clean.

The supplied plug-and-play harness sits between the pedal and the car. Vehicle-specific connector, zero splicing.

STEP 03

Pair the app, pick a mode

Open Rapid Modules over Bluetooth, choose your mode and level, and drive. It remembers your setup.

The delivery curve is brought forward for immediate response with the lightest pedal pressure. Everything, right now.

The real difference

Feel the power you
already paid for.

The lag between your foot and your engine is gone.

Every car ships with a built-in delay in the pedal signal to keep things smooth and soft. Rapid FR erases that delay, so the response your engine already makes shows up the instant you press. No ECU tuning, no wire cutting, nothing permanent. Just your throttle, finally awake.

Doesn't void your warrantyNo ECU flash, no permanent change, no footprint left behind.

Works with everythingPetrol, diesel, hybrid and electric. Analog, PWM and SENT pedal signals, one unit.

Comes off in secondsUnplug it, sell it, or move it to your next car. 100% reversible.

No catch

The stuff people worry about,
answered up front.

No wire cutting

Plug-and-play harness. If you can plug in a phone charger, you can install this.

Doesn't touch the ECU

Your factory tune stays exactly as it left the plant. This only shapes the pedal signal.

Frees your OBD port

It plugs into the pedal, not your diagnostics port. Nothing hanging off the dash.

No monthly fees. Ever.

The anti-theft Pedal Lock is built in and yours for good. Some competitors charge a subscription to unlock theirs. We think that's absurd on a device you already bought.

Your pedal, your phone

Change the whole feel
of your car from the
driver's seat.

The Rapid Modules app pairs over Bluetooth in real time. Switch modes at a red light, save your favorite combinations, and if your phone dies there's an on-device emergency mode so you're never stuck.

Pedal Lock included free

One tap disables the accelerator entirely. A built-in anti-theft mode that turns your own pedal into the kill switch. No subscription, no add-on.

Made in Italy

Since 1991

Rapid FR isn't a marketing brand that ordered a box from a catalog. It's built by Dimsport, the Italian engineering house in Serralunga di Crea that has spent three decades making the calibration tools professional tuners actually use.

That's the difference you're paying for. The same people who build the equipment behind the industry designed the module under your pedal. $229, from the company that wrote the book on it.

Questions

Before you plug in.

Does it actually add power?

No, and we won't pretend it does. It removes the built-in delay in your throttle mapping so the power your engine already makes responds instantly. The car feels quicker because the lag is gone, not because there's more horsepower.

Will it void my warranty?

It doesn't modify your ECU, fuel system or emissions, and it leaves no trace when removed. It shapes the pedal signal only, then unplugs completely.

How hard is the install?

Under five minutes, no tools, no cutting. You unplug the factory connector behind the pedal, plug Rapid FR in between, and you're done. The harness is specific to your vehicle.

My vehicle isn't in the selector. Now what?

Use the checker above. If your exact model doesn't appear, don't guess. Reach out at sales@dimsport.us with your year, make and model and we'll confirm the right fit before you buy.

Can I move it to another car?

Yes. The module is reusable. If your next car uses a different pedal connector, you only swap the cable, not the unit.

What if I don't like it?

Send it back within 30 days for your money back, and every unit carries a 2-year warranty. Ground shipping across the US is free.
