The third-generation Mazda MX-5 (NC Platform / Roadster / Miata) remains a benchmark for lightweight, rear-wheel-drive sports car thrills. Powered by high-revving MZR naturally aspirated 4-cylinder engines (1.8L L8-VE and 2.0L LF-VE / LF-DE), paired with crisp manual or Activematic transmissions and balanced chassis dynamics, the NC was built for pure driver engagement on twisty backroads and track days alike.
However, factory electronic drive-by-wire acceleration introduces heavy signal dampening to the accelerator pedal. This creates an annoying delay off the mark and soft mid-corner pedal pickup—a sluggish dead zone that dulls heel-and-toe downshifts, delays throttle steering balance, and weakens instant power delivery when exiting apexes.
The EliteDrive Smart Stealth eliminates factory throttle lag at the hardware level. By recalibrating the pedal signal sent to your ECU in real time, it restores immediate, linear throttle response—sharpening rev-matching, eliminating hesitation on take-off, and reconnecting your right foot directly to the rear wheels.
Preserve the clean, classic cockpit of your MX-5. Avoid cluttering your compact dash, blocking air vents, or ruining retro sports interior lines with cheap monitors or trailing wires. The Smart Stealth is engineered as a 100% invisible performance upgrade.
Discreet Installation: The ultra-compact module mounts completely hidden out of sight behind your factory pedal box assembly.
Smartphone Control: Manage driving modes, adjust sensitivity levels, and monitor operational parameters seamlessly via high-speed, encrypted Bluetooth connectivity.
81 Driving Profiles: Access 9 primary performance modes (including iAuto, Sport, Eco, and Track/Performance profiles), each featuring 9 levels of fine adjustment. Tailor your pedal response for smooth urban commuting, razor-sharp heel-and-toe rev matching, or aggressive canyon carving.
Encrypted Anti-Theft Pedal Lock: Protect your convertible or PRHT roadster directly from your mobile app. Immobilize the accelerator pedal signal using a custom PIN code—even if someone has your physical keys, the engine will not respond to throttle input until authorized.
Customizable UI Themes: Choose between 3 dynamic mobile app interfaces (Crimson Red, Cobalt Blue, or Crisp White) to complement your MX-5's instrument cluster illumination.

Does this increase overall engine horsepower?
No. The Smart Stealth does not alter forced-induction boost, air-fuel ratios, or ECU ignition maps. It removes the electronic signal delay in the accelerator assembly, giving you immediate access to your engine's existing power band the moment you press the pedal.
How does it help with manual heel-and-toe driving?
Factory drive-by-wire systems often lag when you blip the throttle for a downshift, requiring a longer, unnatural pedal tap. By sharpening signal speed, a quick blip yields an instant rise in RPM, making rev-matching clean and effortless.
Is it safe for factory setup and ECU flash tunes?
100%. The unit connects externally via OEM-style harness connectors. It leaves no trace on your ECU and works seamlessly alongside stock engine software or custom aftermarket flash tunes.
