Why We Removed Our Sequential Gearbox...

...only to fit another one! Seems like a waste of time right? Give Andre a minute to convince you otherwise.

In this 'Today At HPA [UPDATE 293]' chin wag we're talking gearbox replacement that has seen our previous sequential gearbox swapped out for a Holinger SG3 unit. Andre explains why which was a massive decision for the vehicle given the cost of these, however, early reports since the filming of this are that all previous vibrations are gone which has justified the cost already to us, as well as saving Andre on his dentistry bills in the future (no more loose fillings flying around the cockpit).

Also on the list are some of the other considerations around this new setup including the change to paddles, using CAN to communicate the shift from our @MME Motorsport units to the @ECUMaster USA CAN switchboard, and onto our @MoTeC Global M150 ECU which then sends one final Chinese whisper through to the Holinger unit all faster than the time it would take you to get on the clutch.

All that can seems a little complicated when you lay it out like that, but with the way things are now when it comes to the complexity of vehicles in motorsport let alone OEM, in reality it is not and the fundamental skills you need to set something like this up yourself are covered in the CAN Bus Communications course as well as the Motorsport Wiring course material over on the website, link above.
