Why's Ford not allowing people to tune the S650 Mustang?

1. Lawyers always go after the deepest pockets meaning FORD.
2. You started off this chat saying if you were FORD, in that case you would have a very large sum of money in your bank account and you wouldn’t be on this chat site bringing up silly topics

Have you ever considered there are times when not posting is better than posting. Not sure you really added anything other than calling the OP silly! Was it worth it?

Ford never “allowed people to tune”.
In short, aftermarket tuning is cracking the encryption and safety measures put in place on the CPU to allow a user to alter factory values.
2015 security is tissue paper compared to modern computer security.
C8 corvettes had the same issue, and if I recall it took about 2 years to “crack” that ECU.
we’re just now approaching that 2 year mark with the S650s. I also imagine Ford tried a bit harder with their ECU security and here we are.

......as for stealing any on the newer cars just put an analogue kill switch in it. $500 will make it invisible and totally safe for your electronics and Ford will approve it. Half the nation of Ukraine can be on a Cray computer trying to hack your ride and they'll never start it. I have mentioned this on the platform before. Ford Corporate (in writing with a case number) gave me permission to install one. I haven't yet as I just pull a fuse if I'm in a sketchy area.

What a lazy, pseudo-elitist bullshit response lol. If that's all you've got to "contribute" maybe just stuff that up your ass, Cowboy.

dont count on tuning anytime soon. the 2024+ Mustang is what is called a "FNV" or Full Networked Vehicle, which is also what allows it to participate in OTA updates. the 2024 Mustang, along with the 2024 F-150, 2025 Expedition, 2025 Explorer, and other new Ford vehicles also have a new problem to deal with for tuning, TRON. that is the "Trusted Real-Time Operation Network" and is described by Ford as a "cyber security protocol applied to certain modules connected to the vehicle communication networks. This protocol provides a digital message authentication for data being communicated between modules on the networks, to make sure the data received by a module is the data sent by the sending module and has not been interrupted or tampered with by an outside source". here is all the information Ford shares about TRON:

"TRON secret data authentication security keys are applied to modules with motion control, safety critical and security critical functions. Not all modules on the vehicle will have data authentication security keys applied. The secret authentication security keys provide a digital data handshake between the sending module and the receiving module to confirm the data received has been sent by the expected source.

The initial secret authentication security key distribution takes place at the end of the production line, prior to the vehicle release to the dealer. The key update mechanism includes a key management client and key management server modules. The key management client is the GWM and the key management server modules are the modules participating in the TRON function. The GWM generates the keys and distributes them to itself and the server modules, one module at a time sequentially. The keys are processed by the receiving modules and stored in their memory and a backup of the distributed keys is stored in the TCU . After the vehicle's TRON has been successfully configured, the production line end of line tool sends a copy to the Ford backend data systems for storage.

If a TRON capable module is replaced, the module secret authentication security key must be applied to the new module so it functions on the network when installed. When replacing a TRON capable module, run the diagnostic scan tool TRON Module Authentication Diagnosis and Repair procedure to distribute a new set of secret authentication security keys to all TRON capable modules.

The GWM and the TRON capable modules can set Diagnostic Trouble Codes (DTCs) if the keys are misaligned between modules, there are communication issues on the vehicle network or a module is not responding.

The GWM acts as the key management client for the TRON system for creating, monitoring and distributing the secret keys to the participating modules.

The TCU stores a backup of all TRON distributed keys."

here is the TRON network for a 2025 Expedition:

it has the Restraints Control Module, Anti-Lock Braking System, Body Control Module, Powertrain Control Module, Transfer Case Control Module, Vehicle Dynamics Module, Telematics Control Unit, Remote Function Actuator, Headlamp Control Module, Image Processing Module A, Power Steering Control Module, Steering Column Control Module, Gear Shift Module, Driver's Door Module, and Passenger Door Module.

we got off lucky with a much, much smaller TRON network, likely aided by the fact the S650 is a modified S550, and Ford didnt want to completely re-do the Mustang like they did the Explorer and Expedition, but wanted the security. so these are the modules they could justify putting on a TRON network

we only have the Anti-Lock Braking System, Powertrain Control Module, Telematics Control Unit, Power Steering Control Module, and Image Processing Module A

some other stuff about the TRON network:
- a module can only be programmed with so many keys before it must be replaced
- the mentioned "TRON Module Authentication Diagnosis and Repair procedure" requires a connection to a specific TRON server within Ford, and it seems like Ford might be playing favorites with how well this connection even goes
- it is unknown if a TRON issue can cause a no-start condition

of course, this is all speculation. TRON could have no effect on tuning, as it seems to be more of a way to force the use of genuine parts and control who can re-program certain modules. we will have to see what the conclusion is after this is cracked
