Introduction 2023+ WRX MT UsersIf you are using Atlas 2024.4 or earlier, recovery is not possible on these ECUs. Atlas 2025.1 and later resolves this issue upon first programming with the ECU. In order for a calibration (tune) to be recognized completely by ...

Atlas supports the following adapters and hardware through custom cross-platform device drivers that are built directly into Atlas. The listed adapters should work out of the box with no additional configuration required. Device Platform Connection T...

Atlas is a relatively new software project, and while we strive to provide an easy to use and trouble-free product, errors may still arise. In this event, users are urged to check our currently known issues. If this is a new issue, please open a support ticket...

Table Editor The Table Editor is a critical view in Atlas. Using the Table Editor, you can change calibration lookup tables and modify ECU behaviors resulting from their computed values. Most, if not all, recalibration done on your ECU will happen from within...

Interpolation in the Table Editor Interpolation is a feature in Atlas that allows you to effectively smooth table cell data. Using interpolation, you can create gradients that prevent the ECU from suddenly "jumping" in values, helping to avoid detonation and ...

If you would like to revert your changes in the current calibration to another calibration, you can always Apply a different calibration by clicking Edit -> Apply different calibration... The default selection in the Select Calibration dialog box will alw...

Introduction Description Most vehicles have a manner in which you can recover the ECU should the flashing be incomplete. For the Subaru WRX (2015+), for example, your bootloader (never reprogrammed by Atlas) has logic which runs on start that will attempt to...

Introduction In order to avoid risking damaging or "bricking" your OEM ECU, you may instead choose to clone your OEM ECU to another, spare ECU that you have purchased. However, you will run into issues with this without cloning the ECU, as the OEM ECU in your...
