Daihatsu remapping: questions
Will a tuning box affect my Daihatsu 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 remap: which should I choose?
A flash remap permanently rewrites the maps in the ECU and leaves a trace in the flash counter. The GAN tuning box adjusts the sensor signals instead: the ECU stays in factory condition, and you can return the car to stock in about a minute. A flash remap can be the better choice if the engine has upgraded hardware, or if the car is out of warranty and you accept the risks.
