Hello, I own a Specialized Turbo Levo Comp Alloy 2022. at my 12 month service I was advised that my TCU required replacement....... I then considered updating to the Mastermind TCU. I reached out to Specialized & was told over & over it cant be done & Specialized Corporate will not permit upgrade! Despite this a number of forums indicate it can be done & riders have done it.

Q. Has anyone successfully upgraded a TCU bike with a Mastermind TCU & how's it going?

Q. How did you go about it, you need a Authorised Dealer to do the upgrade?

Specialized Technicians indicated that the upgrade may initially work but in the long term Bike may send error code & motor may 'brick'.....

Senario: I bought a Mastermind TCU. When the dealer plugs the new Mastermind TCU into the Turbo Levo the original bikes Serial Number is REJECTED as not being compatible. The bike will not accept Mastermind TCU.

Q. How can the conversion be completed & is it long term successful, without the TCU, Battery or Motor 'rejecting' or locking out the conversion?

I recently read this Post & was concerned at the Specialized Tech Response. Have Specialized actually blocked the 'upgrade' or is this a Corporate response?

Exert: I contacted Specialized Support for information about firmware version requirements or other info I would need to complete the install. Here are the responses,

" Thanks for reaching out to rider care. Unfortunately, the Mastermind computers are not backwards compatible with bikes not originally equipped with the Mastermind display. The primary reason for this incompatibility is technology issues related to firmware updates. Each bike has specific firmware written to the motor, battery, and display, which is then associated with that bike's SN. Plugging in a Mastermind generation computer to a bike not originally equipped with the new system may cause error codes in the system. Attempting to update the Mastermind system with an incompatible SN could result in limited functionality, and in some cases loss of bike functionality, so we do not recommend this exchange and it will not have warranty coverage. I apologize for the inconvenience. "

and after another few questions for clarity on this:

" I am sorry for the misinformation on the web about this. They do not portray long-term use where the incompatibility leads to motors bricking. The TCU2 is incompatible with any model that did not originally come with one. "
