Interestingly McLaren used different brake tubs/covers in Monaco. I would think their adjustable system would come in handy around Monaco but after thinking I guess cooling is the main priority.

This week's Autosport Monaco race review mentions a 'piece of electronic trickery on the McLaren, which has been on both cars all year, and Button is now feeling it may be confusing his feel for the car, causing him to make poor set-up choices'.

Any ideas what this piece of electronic trickery could be? Or how it affects things?

Electronic roll control? They use this on their road car.

So their anti-roll bars are electronically loosened (word?)/stiffened during cornering?

That would be active suspension though.

Q: Autosport magazine has said that Jenson's feel for the car is being "confused" by some "electronic trickery". Any idea what?

A (Craig Scarborough): I don't know, but can only guess it's an engine mapping to replace the fired overrun (hot blown) maps banned for this year.

Q: Guess there's not much else it could be? Any dynamic electronics allowed in terms of steering/braking/suspension these days?

A (Craig Scarborough): No, about the only electronics allowed are in the engine and gearbox.

Cool, thanks.

Spitball time! Direct off-throttle blowing maps are now banned this year correct? So what could they be doing electronically in that direction? How about something that allows a residual blowing effect, which disspates slowly over time once the throttle is disengaged? So the effect of instant loss in rear grip once off-throttle is minimised. This would lead to gradual loss of grip at the rear through slow corners, resulting in slow traction on exit, which seems to be the McLaren's weakness at the moment (correct?). Sound feasible?

Hmm...Interesting take, but once they're on the throttle at corner exit, shouldn't that provide the necessary downforce ? I mean, throttle at corner exit = blowing, no ?

Does the McLaren have to change its car?

I'm talking slow corners with short apexes, not medium speed ones (with gradual exits). The traction issue's only really shown itself in Monaco and Bahrain, which have more short, tight corners than anywhere else so far. In those you have to have some traction to start to apply full throttle in the first place. Watch the Chinese Grand Prix, specifically the hairpin. The mp4-27 is great under breaking into the corner, but even on better tyres they seem to be slow coming out of the hairpin compared to the cars around them. Again, take this all with a pinch of salt, it could be down to the physical characteristics of the car.
