This is what a top MotoGP electronics engineer – who shall remain nameless – thinks…
“The control ECU is the biggest, biggest, biggest ........ that’s ever happened in the paddock. The manpower cost may go down by 50 per cent but the cost of simulation will go up by 100 per cent. With limited functionality from the software you have to spend time on the simulator to run all the possibilities of all the settings to find which setting will give you the most advantage.
“Last year’s Open-class traction control had one-and-a half tables of numbers; now it’s six tables, and all these tables work into each other, so we spend a whole day only on fine tuning, then another day for every track and another day for every condition. Magneti Marelli claim the system is so clever but it’s so old-fashioned. They have no idea. They speak so nice, they sound so clever, but it’s all hot air. It makes me so angry!
“We should keep the control ECU, but let people write their own software as they do now – it’s more cost efficient. If you are working on the traction control to avoid big slides, the control ECU has five tuning parameters for every point – like speed, rpm, torque, spin and so on – so how can one man in a small team set that up? Already the number of total parameters are increasing, from 1500 last year to 2000 this year.
“They say that the unified software will reduce the gap between the big teams and the small teams, but it won’t. The factory teams can afford the manpower, so they will have one engineer working on the traction control, another on the wheelie control, another on engine-braking control, another for the carburation. And what will the private team have? One guy working on all of these on his own! It’s ridiculous!”
Obviously, as Indecisive Dave, I believe every word of this. And I believe MotoGP’s Open riders who complain about this year’s system, which will essentially be the same system used by Rossi, Marc Márquez and everyone from the post-Valencia GP tests onward.
