OK. As in when the engine shuts down, some unburned fuel vapour passes through open valves back into the intake system? And if I never use start/stop they're not needed.
Seems like a lot of effort to do SFA.
As I said to another poster, all the driver needs to do is match revs to road speed, heel and toeing does that on downshifts. The synchros are there to match actual gear speeds.
What double declutching does is trade insignificant syncho wear with double the work on the throw out bearing and...
OK. But it's not necessary. Heel and toeing with extra revs for skipping gears does the job and the synchro cones take car of minor gear speed differences.
When I see this stuff I always ask, who are they, what are their qualifications, who profits?
I remember how the Japanese were going to destroy western car makers in the 60's.
I know nothing about strip settings. But for fast road driving/riding I check pressure rise from cold when the tyres have had about a 1/2 hour vigorous running, I look for around 5 psi rise.
