Description
The Burger Tuning JB4 Tuner for the 2023+ Dodge Hornet 1.3L & 2.0L Turbo delivers peak gains of up to +30whp and +80wtq on a completely stock setup—along with as much as +65whp under the curve for stronger midrange performance. Whether you’re running the 2.0L Hurricane 4 GT or the 1.3L Turbo PHEV R/T, the JB4 transforms your Hornet into a faster, more responsive machine without the need for ECU flashing.
Because the JB4 integrates via a Plug & Play harness and CANbus OBDII connection, it can actively monitor and adjust more than 40 real-time engine parameters—including boost, timing advance, air/fuel ratio, fuel trims, throttle position, and knock feedback. This allows for precise power delivery, advanced safety protections, and a smoother driving experience than conventional “dumb” piggyback tuners.
The JB4 offers 8 preloaded maps for pump gas, race fuel, and up to 30% E85 blends, plus boost-by-gear control for improved launches. It supports in-dash map switching, built-in code reading, and progressive water/methanol integration. Pair it with JB4 Mobile or JB4PRO for wireless logging, map changes, and free firmware updates.
