For years, Jeep owners have accepted an odd fact: Jeeps are arguably the most customizable on the planet, yet they are often the hardest to unlock digitally. Want to recalibrate for tires? You will need one tool. Want real performance tuning? That is another. Add trail controls, including lighting tweaks, diagnostics, and transmission behavior, and suddenly the glovebox looks like a tech center.

That era is ending.
Introducing the Superchips Flashcal+ for Jeep Wranglers and Gladiators. A new app-based performance flash-tuning platform now supports every Wrangler from 2007 through 2025, including JK, JL, and JT, as well as 2020–2022 Gladiators. The Flashcal+ coverage covers the entire modern Jeep engine lineup, including the 3.8-liter, 3.6-liter Pentastar, 2.0-liter turbo, 4XE hybrid, and diesel variants. One system. One interface. No laptop. No wiring.
Above: The 2015–2023 Wrangler (3.8, 3.6, 2.0) and 2020–2022 Gladiator (3.6) can now get Performance Flash Tuning with a simple PCM swap, right through the app. Loaded with Jeep-specific features for JK, JL, and JT, it works on every engine, including 4XE and diesel. This part is legal for sale or use on emissions-controlled vehicles.
At its core, the system relies on a wireless Bluetooth dongle that pairs directly to an iPhone or Android device. From there, everything occurs inside the app. Full performance flash tuning is enabled via a PCM on supported 2015–2023 Wranglers and 2020–2022 Gladiators, allowing owners to reprogram their Jeeps from their phones.
JL and JT models include a Gateway Bypass module to sidestep factory security restrictions, while JK owners can discard it. Installation is direct, and once linked, the vehicle becomes fully configurable.
The Tire Size Wizard is one of the most immediately useful features. Anyone who has swapped tires understands how imprecise speedometer correction can be, particularly once sizes climb above stock. Rather than relying on math or guesswork, the system uses your phone’s GPS to automatically self-calibrate the speedometer.
GPS-based calibration eliminates all uncertainty, but a traditional manual entry is still available for those who prefer it. The system supports tire sizes up to 42 inches tall and super aggressive gear ratios up to 5.38:1, placing it squarely in the realm of serious builds, not just mild upgrades.

Performance tuning is where the system separates itself from simple calibration tools. Owners of 2007–2014 JKs can open full in-app performance flash tuning to enrich torque response, power delivery, transmission shift speed, and firmness, and even fuel economy. Optional throttle booster functionality adds adaptable pedal sensitivity, allowing drivers to tailor throttle response for commuting, crawling, or towing.
The calibrations themselves are dyno verified and available for both 87-octane and premium fuel, with additional control over speed limiters, idle speed programming, and cooling fan operation. It is not a generic tune; it is Jeep-specific performance engineering.
Off-road capability is enhanced by the app’s CRAWL Screen, a live control interface designed for trail use. Depending on the year and trim level, drivers can engage front and rear differential locks, temporarily disable TPMS, or raise the engine idle speed from 500 to 2000 RPM for winching or recovery.
Specific arrangements even allow axle locking in two-wheel drive, high range, and low range. These format changes do not require a static vehicle in a parking lot, but rather, they are real-time management that responds to varying terrain.
Above: Flashcal+ is the first GPS-based tire calibration tool, keeping Wrangler and Gladiator speedometers accurate. Its Crawl Screen lets you control off-road features, sway bars, lockers, winch idle, Rock Lock, and TPMS, on the fly.
Beyond performance and trail features, the system dives deep into the details Jeep owners care about. Daytime running lights can be reassigned to halos, fenders, fog lights, headlights, or turn signals. The Flashcal+ can enable or disable DRLs, fog lights, fog light dropout, traction control, sway bar disconnect behavior, and horn chirp on lock.
TPMS can operate across a wide pressure range or be disabled entirely for aftermarket wheels. The app also allows one-touch lane change, tow package configuration, auto headlight behavior, and accessory delay timing. These are the minor annoyances and preferences that owners usually live with, or chase across multiple devices, now managed in one place.
The platform also functions as a complete diagnostic and monitoring tool. Live data can be displayed via customizable digital gauges, and diagnostic trouble codes can be read and cleared directly in the app. Whether overseeing operating data or clearing a check engine light after a repair, the information is always available.
Above: Connect your Jeep effortlessly via Bluetooth using the wireless dongle, compatible with both Android and iPhone. No messy wires, no complicated setup, plug in and go.
What makes this system stand out is not any single feature, but the way everything works together. Performance tuning, trail controls, lighting configuration, diagnostics, and calibration are unified in a single, wireless interface.
For Wrangler and Gladiator owners who want to liberate their Jeep’s full potential on the street, on the trail, and everywhere in between, the Superchip Flashcal+ is not just another tuner. It is the missing link between Jeep hardware and Jeep potential.
