Well, the F-Series cars which share the Infineon TriCore ECU's have been cracked and can be flash tuned now. Real flash tuning, not just flashing some of BMW's own files that have been leaked.
There is more than one source on this and Bimmerboost can not share all the details but the one we can mention is Flashtec from Switzerland. They are taking pre-orders on their flashing device.
You have to be one of their dealers to get the details but fortunately we have members who have access to the customer page. Their device is set to ship next month:
CMDFlash BMW Fxx PWD READER for Tricore Bootmode
( Special Probe and Plugin, you must have Tricore bootmode )
Shipment from January 5th 2015
Now this is an ECU out method. It means the ECU needs to be physically removed and sent in to a tuner. We hear an OBD-II method is on the way from someone but they want to keep this quiet and for themselves for obvious reasons. The first one to get it gets the gold, right?
What they seem to be doing is generating their own RSA key pair to bypass BMW's verification method. If it sounds like BMW makes tuning a bitch that is because they do. They just are not any fun any more these days.
Another source claiming to have ability is Russia's Avtotools. Whether they do or not we do not know but their release is scheduled for this month:
ECU-Explorer tool exclusively designed to read Infineon Tricore MCU’s over CAN-bus.
Supports Read/Write EEPROM function for secured and non-secured SAC-TC1766, SAC-TC1767, SAC-TC1797 microcontrollers.
ECU-Explorer comes with Mileage, DPF, ECU system time and ISN built-in calculators.
Purpose of use:
- Change power level (320-328) (System time reset only, you must use ESYS for coding and ISTA to make final programming)
- Switch OFF oxygen sensors (System time reset only, you must use ESYS for coding and ISTA to make final programming)
- Switch OFF check engine lamp(System time reset only, you must use ESYS for coding and ISTA to make final programming)
- Reset mileage
- Reset system time
- Change ISN (for engines N13,N20,N55 etc.)
Supported ECU types:
MEVD1725 ( N13 ) F20 ,F21 Серия

MEVD172G (N55) F10 F20 F25 F30 F32
So what does this mean for tuning? It means real tuning options will open up not just those relegated to piggybacks feeding the ECU info to increase boost. If people wanted to go beyond just increasing boost on the stock turbos this is the key for that to happen. Now we will finally see things like turbocharger upgrades for the N63, S63, S63TU, S55, etc. with the tuning to make use of the hardware.
An M5 with upgraded turbos may finally be a reality next year. The BMW guys will not have to allow the 63 AMG's to have all the fun any longer.
The other issue now will be watching tuners all fight for superiority and we will see who rips off whom as this spreads. It also makes tuners claims from years ago about doing turbo upgrades on M5's seem funny now when you consider they had no way to tune the cars and it has taken a good 5+ years to crack these ECU's. We are barely in the infancy of it all right now.
