With this function,LAUNCH X431 PRO3 ACE will improve vehicle performance, customize individual customization, refresh hidden functions, disable the annoying functions, code the adaptive data for certain components after repairs or replacements, customized configurations for high-end models,etc to enhance fuel efficiency and ensure safe driving.

1.Online Coding: this LAUNCH scan tool can directly access the online vehicle repair data to do high-level repairs.

2.Offline Coding: read the code from the original module, and then write the code for the new module,for example ,write a VIN to new ECU.

3.Component Matching:Matching,relearn ,Cali-b-ration, or initia-li-zation adaptive data for certain components after repair or replacements,such as: suspension cali-b-ration ,seat matching ,sunroof initia-li-zation,gearbox matching,injector cali-b-ration, transmission adap-t-ion.Delete Adap-t-ation Data, Tank Cali-b-ration,Height sensor system cali-b-ration,PSM Sensor Cali-b-ration ,etc.

4.Re-trofit & Mo-dification: for example, re-trofit battery with different type, Upgrading the headlights, taillights, and interior lighting to LED lights,etc.

5.Refresh the Hidden Features:for example,disable auto start-stop, disable daytime running light, disable safety belt chiming ,delete transport mode .delete transmission adaptive value.setting speed limits,etc.

Examples of ECU Coding:1)The new Ford Focus can be upgraded to a tire pressure monitoring function by flushing the ECU. This feature is especially important for those who like to drive long distances, significantly improving the safety of the car;2)Mercedes-Benz E-Series can change the much-criticized air conditioning mode by brushing the ECU to improve passenger comfort;3)VW Passat can be swiped to "modify home/leave time";4)It is important to note that, due to hardware and other reasons, such as the Audi Q5, if you want to brush the "home/away function", you must have the automatic headlights function. ***Note: All above functions are not compatibility with all vehicles, please send car make, year, model, VIN# and functions you need to us to check vehicle compatibility.
