JAC Chip Tuning
Up to 30% more power for your JAC
The JAC catalogue lists 10 engines (models: 9, generations: 9). For 30% of the engines, there are the GAN GT (up to 30% more power) and GAN GTL (up to 25%) tuning modules; for 7 naturally aspirated engines, the GAN GA and GAN GA+ (up to 12%). Each engine’s figures are on its own page.
JAC chip tuning without an ECU remap
The tuning module sits between the sensors and the engine control unit (ECU) and adjusts their signals. Your manufacturer’s warranty is preserved: the ECU software is never changed, and the module can be removed at any time.

JAC chip tuning: questions
Does the GAN module affect my JAC warranty?
No. The module does not change the ECU software and can be removed at any time, so your manufacturer’s warranty is preserved. We also give an engine warranty: 2 years with the GAN GT, 1 year with the GAN GTL.
Tuning box or ECU remap: which should I choose?
An ECU remap permanently changes the maps in the ECU and leaves a trace in the flash counter. The GAN tuning module adjusts the sensor signals instead: the ECU stays in factory condition, and you can return the car to stock in about a minute.
