GAC chip tuning: questions
Does the GAN module affect my GAC warranty?
Your manufacturer’s warranty is preserved: the ECU software is never changed, and the module can be removed at any time.
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.
