Shifting experiment, interesting results.
Shifting experiment, interesting results.
Because the question how to shift keeps coming up I decided to do a little test.
Five heats of each shifting method. Flat, lift, gated and auto clutch.
Test conditions:
Cars: Stock
Track: Hockenheim 1/4 mile
Launch: Pinging off the rev limiter
Clutch: Flat and lift shifting with button, Gated with the clutch pedal.
6Th. time is the average time for that shifting method.

So it seems that flat shifting is NOT the fastest way, in cars with a normal manual lifting
on the upshift is quickest but in cars with a twin clutch or race sequential transmission
(and possibly a stock auto) the auto clutch is quickest.
I'd say, and tyhe numbers seem sto lead that way, that rev matching and the torque of the vehicle seem to be a factor. The smaller cars aren't as affected as they don't light up the tires as easy?
I've always said R1's should be run without clutch, they're designed that way, just not sure T10 knew that (or got it right).
Auto clutch means manual without clutch, I only thought of it now that the CSR E wheel has an auto clutch option on the wheel. I don't own one so I can't test that.
Flat shifting means keeping the throttle open on the upshifts.
Lift means lifting the throttle on the upshifts.
Gated is the 6+1 H-gate shifter for the Fanatec wheels.
TCS was off for the tests.
Not trying to be a dick here, but since this was done with a single driver it isn't really a fair example of how things work. If someone is faster/slower with their feet/fingers than Zeratul then the data will be skewed based on the skill level. Like Trackassasin said, there's too many variables (the driver being the biggest one in my opinion).
I'd suggest each driver run their own test to find out what is fastest for them.
basher also confirmed this in FM3 :)
