The latest Atlas update is now available on the site! Aside from some housekeeping, the big change here is the addition of station mode for the wireless connectivity and adding boost control editing to the main UI (just the enable selection). On the FCU side, there's the addition of editable closed loop re-enable delay as well as some updates for the upcoming Advanced Power Management operating system for the E92.

Pic for attention. 😆

We learn, we iterate, and we turn that into something useful for you. This is something I set out to do months ago, and we’re finally happy with how it behaves. Traction control for the factory E92 was at the heart of this project, and it required learning a lot of techniques along with really digesting what the factory code is doing.

It’ll be a bit before we can get this out as it’s a significant amount of code to inject and iterate across operating systems, but we’re also looking to take steps to protect it from copying at the same time. We swear… this won’t be vaporware. 😂

This is the next evolution of the E92 patch for Atlas. This will all be available in E90/E99 as well.

This was something on the to do list for a while… better late than never, right?

The next UI update will allow you to connect your Atlas to your home or shop network, and then any time you enable the WiFi, it can be set to automatically connect. From there, you just type the IP address assigned into the browser bar, and you can do everything you normally would. The benefit of this is a tuner can remotely log into your computer and do whatever they need to if they want to set your Atlas up for you. All you need to do is the physical enable of the network!

For a NA car that made ~535whp bone stock, I’d say this is markedly impressive for one single modification that won’t require swapping tunes and test tubes. 👀👀

We’re at 1stphorm for Cars and Caffeine this morning, so stop by and say hi!

We’ve been quiet, but we’ve been busy!

Global B Atlas is nearing the vehicle test stage (we’re behind, we know, but it’s worth it). Since we have to build all the E99 operating systems ourselves, we’re making sure all the features from the E92 are present along with some new ones. Here’s a sneak peak at what we’ve got coming. 👀

What would you like to see your factory ECM do?

Not business related at all.

We found these little guys hanging out under a car in the parking lot. If anyone around St. Louis is interested in a couple of healthy looking kittens… have at it. They’re pretty friendly and calm, and appear free of fleas or ticks.

"More are coming."

We're in the process of updating the base Atlas E92 operating systems, and when complete, we will begin patching all new orders with the latest OS mods. Any previously patched vehicles will be able to submit their file for updating as well!

In addition to the variable max injector duration versus engine speed and a background fuel flow calculation fix (this really only affects fuel pump control), we're adding:

-PE modifier based on cylinder airmass and port fraction
-Delta fuel control mode (allows a returnless fuel system to act like it has a 1:1 regulator based on what fuel mode you're in)
-Minimum end of injection enforcement (since some people like bowling with gutter guards)
-Overboost and low fuel pressure fuel cut off safeties
-Scheduled gain for fuel pump control (meaning you can tamp down the control loop at low fuel flow, but still have fast acting adjustment at high flow)

Now's a good time to make suggestions if you want something incorporated! Have you wanted the factory ECU to do something specific? Let us know!

A couple of modified OEM patterns are headed out the door! We are churning these out as fast as we can, and we just took in another 14,000lbs worth of blanks to try and keep up while keeping the price down as aluminum continues to go up.

Left:
Kingsport Grey
“LT4” replaced with “Z06”

Right:
Blue Tropic (matches Wave Metallic/Riverside Blue)
“Supercharged” replaced with “Camaro ZL1”

Please note that custom lids like these don’t happen overnight as we have to order your color, coat it, and then set up the engraving so please be patient. It’s worth it!

We're happy to announce that the Atlas 2.0 firmware is finally ready for full release! This is overdue but... better later than never, right?

"But we just want boost control!"

Good thing that's the core of what this is! Along with a few other goodies that you can read about in the release, Titan's Grip is now fully supported for both LT4 and 2650 applications meaning yes... you can now purchase it. The retail price for Titan's Grip is $600 which includes everything you need. You WILL need to pin the Atlas connector itself. If you have ever pinned an ECM (installing the Atlas should ring a bell), you can install the Titan's Grip just fine. We're working on more detailed instructions, so early adopters will likely have questions which we are here for.

Head on over to the Tech Blog to read about the update, download it, and enjoy the latest and great!
