There are 3 stages:

• TCU software update
• TCU maps update
• XDF and ADX files in Tuner Pro

IMPORTANT NOTES

If the new SOFTWARE includes new features, they will not work without updating MAPS.

If the new SOFTWARE only includes corrections to the previous version but does not add new features, then there is no need to update the MAPS.

New features may also not be visible in Tuner Pro if you do not update the XDF & ADX files.

The new SOFTWARE will work fine with the old MAPS file but the new features will not work.

It’s best to update everything together.

The MAPS update removes the configuration.

Remember to make a MAPS backup before upgrading. The new MAPS base files must be edited for your vehicle
