Jeep owners are no strangers to customization. Whether it’s lifting a Wrangler for off-road dominance or fine-tuning tire and gear ratios for better drivability, modifying a Jeep is as much a part of ownership as the trail rides themselves.

The Superchips Flashcal+ is a new spin on our class leading, app based, mobile options control device. Support is available for both iOS and Android platforms! It offers a digital gateway to tailoring your Jeep’s performance and function to most any given situation, delivering a broad range of vehicle calibration tools designed to match mechanical upgrades and improve the driving experience.

Here’s a closer look at what the Flashcal+ brings to the table for the 2007–2018 Wrangler JK (3.8-liter and 3.6-liter), the 2018–2024 Wrangler JL (3.6-liter and 2.0-liter), and the 2020–2024 Gladiator JT (3.6-liter) platforms.

Feature-Rich Calibration for Modern Jeeps

At its core, the Superchips Flashcal+ is a diagnostic and calibration device that plugs into the OBD-II port and gives Jeep owners control over many key electronic parameters. Unlike basic handheld tuners, the Flashcal+ is designed for those who want utility without necessarily diving into performance tuning (though it is upgradable to Flashpaq for added power).

Some of its standout capabilities include:

Tire Size Adjustment

Jeeps often roll out of the garage with bigger tires than stock. Flashcal+ allows tire size calibration up to 41 inches, correcting the speedometer, odometer, and shift points for automatic transmissions. This is especially critical for JKs and JLs running 35s or 37s and wanting accurate road manners.

Axle Gear Ratio Calibration

After a gear swap (say, from 3.21s to 4.88s), improper calibration can throw off shift points and cause performance issues. The Flashcal+ lets users match the ECM to the new gear ratio for better drivability and reduced transmission strain.

Tire Pressure Monitoring System (TPMS) Adjustments

Whether you’re airing down for the trail or running a different wheel and tire combo, the Flashcal+ enables TPMS threshold adjustment or disablement (where legal), helping to eliminate nuisance dash lights.

Transfer Case Ratio Support

For those who have swapped in a Rubicon 4:1 transfer case or an aftermarket unit, the Flashcal+ can recalibrate for transfer case gear ratios, ensuring accurate shift behavior and dash readouts.

Lighting and Safety Features

Owners can enable or disable Daytime Running Lights, change lamp behavior for European spec lighting, and adjust fog light dropout settings. It also allows you to modify horn chirp on lock/unlock and customize headlight delay.

One-Touch Lane Change Adjustments

This lets you adjust how many times your blinker flashes with a tap—a small but useful touch.

Electronic Sway Bar and Locker Options (Rubicon)

For Rubicon models, Flashcal+ can recalibrate locker activation parameters and manage sway bar behavior to accommodate lift kits or aftermarket sensors.

Read/Clear Diagnostic Trouble Codes (DTCs)

Basic scan tool functionality allows for quick troubleshooting without a visit to the dealer or shop.

Platform-Specific Capabilities

Wrangler JK (2007–2018 3.8-liter & 3.6-liter)

The JK series marked the modern explosion of Jeep's aftermarket. With thousands of Jeeps lifted and modified, recalibration is essential. Flashcal+ supports the entire JK run, offering fixes for gear swaps, large tires, and TPMS concerns. Owners with the earlier 3.8L engine still benefit, despite it being less electronically complex than later models.

Wrangler JL (2018–2024 3.6-liter & 2.0-liter Turbo)

With the JL, Jeep added more tech—and more complexity. The Flashcal+ keeps up, offering the same tire/gear calibration tools but with added attention to the turbocharged 2.0L engine’s nuances and newer electrical architecture. The JL's CANbus system is more finicky than the JK's, so having a tool like the Flashcal+ helps avoid ECU misfires when changes are made.

Gladiator JT (2020–2024 3.6-liter)

Jeep’s truck brings trail capability and utility in one platform, and it’s often modified for both overlanding and towing. With the Flashcal+, Gladiator owners can fine-tune their setups post-lift, especially with larger tires, winch bumpers, and camper setups that often necessitate gearing changes.

Follow The (Upgrade) Path

The Flashcal+ is not a performance tuner out of the box—it doesn’t increase horsepower or torque. “However,” says Senior Product manager Michael Litsch, “Superchips offers an online upgrade path to convert the Flashcal+ into a Flashpaq, unlocking power tuning for 87 or 91-octane performance, towing optimization, and economy modes. This dual-purpose upgrade makes Flashcal+ a future-proof investment for Jeep owners who may want more later.”

Whether you’re dialing in a lifted Wrangler JK, tweaking the drivetrain on your JL Rubicon, or outfitting a Gladiator for the next backcountry trip, the Superchips Flashcal+ offers a practical, affordable way to ensure that your Jeep's brain matches its brawn. With broad compatibility across Jeep platforms and a host of customizable settings, it's a must-have tool for any enthusiast serious about their build’s drivability, legality, and performance.
