It has taken a while, but we're finally ready with the Atlas 2.0 firmware! This update is pretty comprehensive, but it's well worth it. I'll go into more detail later but the main highlights are:
- Dark mode!
- Boost control via Titan's Grip is now fully supported
- Enhanced crank decoding logic to accommodate poorly performing crank sensors
- Logging through HPT's ProLink (and direct to MPVI) to allow logging in Global A E90 applications
- Basic code reading built into the UI
- Multiple feature additions/refinements
Download the new UI firmware here.
Download the new FCU firmware here.
Download the new KSF settings file.
Download the TunerPro XDF for editing Atlas here.
To update, download the Atlas UI, FCU, and KSF files listed above, then connect to your Atlas via WiFi. You'll want to click LOGIN, then navigate to SETUP, and finally to UPDATE UI. Upload the UI binary file you just downloaded and allow it to complete. When it finishes, you'll need to reconnect to the WiFi (however, it should automatically trigger the WiFi, so you won't need to do the gas pedal or brake/cruise activation). Once you've successfully reconnected, navigate back into the Atlas and login again. A number of warnings will likely pop up; this is normal. Click through them, and when they finish, go back to the SETUP page and update the FCU with the binary from above. Allow it to complete the update process for the FCU itself (this will take a little longer). Once that's finished, go back to SETUP and upload the KSF file. It will have options, and you do not need to have it flash just yet. You can navigate back to the main page and change your injectors, and once you do, go ahead and click Flash FCU at the top right of the page. If you want to work with the more advanced features, you'll need to navigate back to SETUP and then download the settings file.
The settings file is a .ksf extension that is editable in TunerPro using our definition file. If you open TunerPro, you can navigate to FIle -> Open and select this .ksf. Once that's open, navigate to XDF -> Select XDF and select the .ksf file provided above. Think of the .ksf as the actual data and the .xdf is decoder ring. At the top of the Parameter Tree, select View By: Parameter Category. This will sort things out in a meaningful way. From here, you can poke through and see what's available. The usual suspects are there, but things worth mentioning include:
- Cylinder modifier is now modifiable by airflow
- Injector harnesses can now be installed from the opposite direction (so blue wire at the rear cylinder) by changing the Injector Harness Order Flip flag
- Boost control for LT4 (via Titan's Grip), Magnuson 2650 (via Titan's Grip), and the LT5/2650 (GM electronic bypass) now available [note: Titan's Grip requires a key on engine off learn function to run)
- Turbo boost control for a single MAC valve available
- CAN3 Setup for logging - set to 1 if connecting to HPT ProLink, set to 2 if connecting directly to the MPVI through the 4-pin M8 screw connector
For the boost control users, we'd encourage you to thumb through and view the verbose descriptions for the parameters. You've got a number of things to choose from including ethanol, knock retard, charge temperature, transmission gear, front wheel speed, and drive mode to tailor your boost response the way you want. We have a traction control algorithm as well intended to target ~10% wheel slip, but this is all calibratable. Please note that this will overlap on top of factory traction control. If you disable factory traction control, the Atlas will still try to regulate boost based on wheel speed unless you set the Wheel Slip Decrement Threshold to a very high number.
