Show original supplier description
The Superchips 3545 Flashcal tuner is a user-friendly device for Dodge and Ram trucks, offering an affordable solution for speedometer recalibration. This handheld programmer allows you to correct your speedometer for tire sizes ranging from 25 inches to 42 inches in diameter, and it also supports recalibration for gear or axle swaps. The Flashcal tuner features include speed and rev limiter options, TPMS adjustments, the ability to read and clear diagnostic trouble codes, and displays for digital battery voltage, real-time data logging, and real-time data monitoring. Once connected, you can select your new tire size or gear ratio, and the device will calibrate your truck's systems accordingly. The Superchips Flashcal tuner is compatible with a wide range of Dodge and Ram trucks, including gas models from 1998-2020 and diesel models from 2003-2016. Some sources also indicate compatibility with specific 2018-2019 Ram 1500 Classic models with the 5.7L V8 engine. However, it's important to note that this device may not work on trucks with custom modifications. Additionally, some Superchips products may not be legal for use in California or other states with similar emissions laws.
