Do we know what sort of upgrades McLaren plans to bring to China?
Of course not but I'm sure there will be quite a few. They've basically known since BCN #2 the car was off. I'm sure the team intently focused on the problems and started working on new developments. They've had 3 weeks since then which includes winter testing data and I would say one GP worth of data to help with the new parts(to arrive in time for China), and obviously there's 3 more weeks until China. I would bet that MaCa won't bring the house so to speak in China, but introduce a few crucial updates to confirm they're on the right path and bring the house in Spain as China & Bahrain are back to back.
Of course I could be wrong, McLaren may opt to use a straightline test before China to confirm progress and bring everything to China. Either way I bet we see a competitive MP4-28 by end of the Spanish Grand Prix.
Edit: Sorry Obi obviously I didn't answer your question. Just giving my thoughts.
