Did firmware update and now the engine goes lean

Post by brad3874 »

I was having my car tuned the other day and just about had everything dialed in, we were about to make a couple last small changes and a message popped up telling us to update the firmware. So we did but after the update completed the engine would go super lean under any engine load. No mater how much fuel you added it will not have an effect on my afrs. All my sensor inputs seem to be reading correctly. The car ran perfectly before the firmware update. Fuel pressure is fine, has a new fuel pump, ,injectors, and filter. Any ideas?

With everything plugged in and the ignition in the on position, go to the Help menu and click on “send feedback”. Include a detailed description of the issue.
