I know this has been covered before, but was wondering if anyone has recently tried to retro fit a new mastermind Tcu to a gen 2? I see certini have them available for sale….for over £400!!! 
I have the opportunity to get a new one which has been supplied as a warranty replacement, but it’s not needed.
