2022+ WRX Accessport Fast Flashing

Our Accessport and Off The Shelf Maps continue to be the best first modification for VB WRX owners.  Turning up the power is effortless and drastically improves drivability as well as the ‘smiles per gallon’ factor.  One pain point of tuning has been the 8+ minute flash time whenever a map change is necessary.   While this may not be a big deal for those who are not flashing often, it definitely slows down custom tuning sessions.  Longer flashes can also be a nuisance for minor tune changes for fuel type, etc..  Today we are excited to change that with the release of Fast Flashing for all VB WRXs!

Our software team has implemented an all-new flashing strategy which reduces flash times by up to 15 times.  Instead of flashing the entire file, the map change process will now only flash blocks where data has changed.  In our testing, we have seen flash times as quick as 30 seconds.  Flashing time will increase depending on the number of changes to the file being flashed. That said,  a full flash will not surpass the standard full flash time of ~8 minutes.  Instances where the full ROM is being flashed (Install, Uninstall, etc.) will still flash the entire file.

In order to take advantage of Fast Flashing, your Accessport must have up-to-date firmware and be using a map file that supports this strategy.  COBB Off The Shelf Maps are updated and custom tune files will need to be re-saved in Accesstuner Pro in order to use this feature.  More on that below.
