Hi! I have a JB4 and a single turbo installed with all supporting mods on an 07 335i. I ran the single turbo backend flash, and the flash went flawlessly and the car ran well. No flashing issues.
Recently, I had my tuner adjust some timing values and send me a new bin file. I tried that backend flash on my Macbook, and upon trying to write the ECU, it says that the flash failed and that it would not authenticate the control module. The fuel pump ran continuously in this process. I disconnected the battery for 5 minutes and repeated this process 5 or 6 times. Same issue every time.
What should I do to get my car started? I am home for the weekend and have a business trip I have to make on Monday (oops). Right now it will not start, and when I turn the ignition on, the fuel pump runs continuously, regardless of whether or not I am connected to BimmerBoost.
Any and all help is greatly appreciated!
