Other Mastermind (TCU 2) "How to" guides

[Harpo]

I just stumbled on a mastermind
specific setting in mission control that I haven’t seen or heard mentioned anywhere:
“Calibrate bike to phone elevation”.
In the main screen touch the bike serial number > gear icon > slide the switch on.
Seems to work in my garage and I’ll test it out more next ride.

There's also a jump distance screen but I can't see it in the list of available parameters???? Any ideas anyone?

I came here with the same question. I wanted to try this new feature.

Screen section, you will see Jump Distance, Time and number of hops (beta)

From this discussion, it seems clear that it 's not possible to use the Mastermind TCU on a model older than 2022 with the last Firmware. But on a 2022 Aluminum version or the new Carbon Comp, would it be possible to upgrade to the Mastermind TCU? Is this upgrade supported by @Specialized Rider Care

 

[Fabiods]

Hi, the Mastermind TCU work very well with last firmware of motor and display too. I bought last year the new TCU for my Sworks 2021, I have upgrade with new firmware when it was available. The only weird message it gives is as soon as you turn it on, it tells you "component swap", but it disappears after a few seconds.
However, I must point out that all the updates were made with the TCU mounted on a Sworks 2022, mine too, and then moved to 2021, since the only intelligent part of the whole chain is only Mission Control which notices the change and refuses. To update it if it is not mounted on the 2022 and corresponds to a bike with Mastermind. But once the Mastermind has been disassembled on the 2022 bike and mounted on the 2021, he no longer notices anything, the Mastermind works on the previous bikes.

Hi !

To get full funtion and no "component swap" You can teach the Mastermind to the 2021 Motor in the 2021 Bike in mission control with using your 2022 S-Works Serial number

Best regard,

Chris

Is it possible to swap the serial number in Mastermind?

 

[Christox]

Sorry i meant turbo studio. There it can be done by Speci Dealer

You have to update the bike and the app. I've had the jump feature working for over a month. You can see your data on the phone and on the bike, pretty cool feature

 

[Fabiods]

this function is very inaccurate, it only marks very long jumps and sometimes not even these or sometimes where I have not jumped, Garmin Edge 503 is much more precise also marks small jumps

I just purchased a new TCU2 (mastermind) for my 2021 Gen 2 Levo. I'd try the swap and report if it works or not once it gets here. I wonder if the people that reported it as working used a brand new unit or one that was transplanted from a working Gen3 bike ? and if it was transplanted maybe the firmware on TCU2 needs to be updated first or the initial sync to the correct gen3 bike ?

 

[Fabiods]

Hi, first you activate the new TCU with an bike Gen3 by friend dealer Specialized and after swap to Gen2

 

[behindenemylines]

Hi, Have you ever figured out on how to fix the component swap error message. Someone mentioned that it's possible to add old bike's serial number to the TCU via dealer's workstation. I also noticed that some reported as not possible

 

[Fabiods]

Yes, I read about it, but I don't try it, the problem is find a dealer very friend for it, and remember when I sell the bike that the serial number is not correct, tha people are very suspicious with this changes. But I think that is very nice erase the swap error when started, and after the changes serial number I think that you can use the app Mister Mind too

 

[behindenemylines]

Ok, thanks for help and pointers- got it to work.

As noted above. New TCU2 display comes in a default factory firmware, locked to 15kmh. There is no way to upgrade it without an actual levo that originally came with that tcu. You need to do the upgrade on gen3 bike and then plug it into your gen2. Can’t do it on Gen2 via MC , it has to be done via the dealer workstation. Took about 5 min.

I found a very friendly dealer who was willing to help (my next bike will be purchased from them ) . I no longer have a swap warning messages and I can upgrade all the components (motor, battery and tcu) directly via MC once paired. I did have to reinstall the app.

No also can be done in a gen2 Bike, but you have to use the gen3 Serialnumber of "your" gen3 Bike and perform a "Components swap TCU" in Turbo Studio



Best regards,

Chris

Hi what about Kenevo gen2? I have 2020 expert model which is the same as 2022 except the mastermind. Lets say my tcu is broken and I would like to buy a new one?

 

[BlueThunder]

I have had the Mastermind TCU installed in my Levo 2020 for about a year now and have not noticed a "Comp Swap" message or any problems yet.
I am still riding with the previous owner's serial number (Kenevo SL).
Do any of you know if the serial number in the Mastermind TCU has any effect on the motor or battery management?

Any effect on the motor and battery management.

 

[BlueThunder]

Any effect on the motor and battery management.

The last 1000km I could not notice any difference from the old TCU!
So the difference between the old TCU with Levo serial number and the new mastermind TCU with Kenevo SL serial number
how should the effects be noticeable?

@BlueThunder were you able to use the lock feature with the new TCU? Seems you have to register with Specialized.

I don’t use the lock feature.

@BlueThunder Thanks for the info. Last question, I found a TCU online and want to install today. Did you remove your bike and then install and re-add it in Mission Control or, just swap it in and go? I have a '22 Comp Alloy. Any tips would be greatly appreciated. Let me know and Vielen Danke!

I connected the Mastermind TCU and it already worked. With the old TCU you had to enter a code with the new Mastermind TCU you just have to hold your smartphone near the TCU to pair it. But I‘ve the Levo 20…

BTW: Does anyone know if the TCU really changes the driving characteristics, because I have the serial number of a Kenevo SL.

Even my specialized dealer could not tell me that

 

[etoni]

what is this range since??

Does the gen3 donor bike get altered in any way by using it to activate the new mastermind for a gen2 bike.

A friend has kindly offered that I could use his gen3 bike but obviously i don’t want to cause any future trouble for him.

Hey folks. Do we have any news - recommendations on this?
I just bought a SPECIALIZED TURBO LEVO ALLOY

MOTOR: Specialized Turbo Full Power System 2.2 Motor.
UI/REMOTE: Specialized TCU, 10-LED State of charge, 3-LED Ride Mode display, ANT+/Bluetooth®, w/Handlebar remote.

and did not notice it did not have the Mastermind TCU so I am loking into ways of doing this.

Seems you need a friend with a bike that had the mastermind tcu from new. You buy a new mastermind tcu. Fit it to your friends bike. The bike goes into limp mode. You then take it to a specialized dealer who will activate it to clear the problem.

Get home and fit newly activated tcu to your bike.

I’m struggling to find a dealer to program it. I’m just not a good liar when they ask questions.

Shame specialised makes us jump through these hoops. If you are willing to pay the cost of a tcu they should just provide the ability to program it in and update a low spec or older bike without questions.

Alternatively buy the basic tcd screen and mount it on the handle bars.

Downside is it breaks in a crash. Time doesn’t update when the clocks change and it’s not backlit so you can’t read it in low light or at night. Plus it looks messy on the handle bars.

I have to say I wish I’d never gone down this rabbit hole trying to retro fit the tcu. It’s cost intensive and annoying that it’s unofficial and you must beg for help.

Hopefully you have better luck.
