Had a chat with a very helpful Mclaren chap about why my cars pre cog feels different since the various software injections, upgrades and virus attacks.
He said that the 2013 cars have a different steering wheel pre cog that is controlled by software whereas the 2012 cars have a micro switch that triggers demand to the box control panel. Don't quite understand the difference but stay with it.
So, since the new software the micro switch can be overridden by the software if it determines that the speed being travelled is fast and a quick gear change is needed despite the driver thinking they have pre cogged, ie it will just change gear ultra fast as that is what is needed at speed.
I think this is very noticeable. At speed pre cog seems to have no impact. Now it makes sense as the box knows it needs to change tout sweet.
This happens on up and down changes......what I don't quite understand is that pre cog allows the driver to prepare for altering sequence from up the box to down the box.........so if you are on a road where you make a number of up changes at high speed then know a few down changes are needed before a tight bend then pre cog helps. I can only assume the new software picks up deceleration or slight dive and knows a down change is required.
So the box now has a learning element that alters change speed depending how loony the driver is.
Do the other early adopters find this difference ?
