Please give us ideas you think would be good for an advanced class.
Stuff like CAN hacking/integration, spec'ing and designing spline couplers, designing motor adapters, EPAS integration, pretty much things that are not plug and play in a build and need bespoke reverse engineering and fabrication/machining.
The intermediate course is great - I almost pulled the trigger, but for $2000 including travel, my preference is for new material, personally, not review. I am guessing that would apply to several people here, but more importantly, ask yourselves what's next after the intermediate course you are doing in April as far as next level. Michael knows the answer to this better than I do.
