I can tell you how I do it
Good Morning,
I have a 1993 Metro with the Xfi cam and a Swift tranny.
The goal with these two was best FE.
The Xfi cam has less horsepower but more bottom end torque.
The Swift trans has a tall top gear due to the lower ratio final drive.
So that being presented;
...I shift out of first as soon as the car is rolling. (the torque from the cam lets me)
...Out of second into third when the engine sounds right. (I have no tach, I listen for the engine to quit sounding "loaded") Usually around 10 to 20 MPH.
...now here is where I get imaginative, If I am head down a straight road (highway or byway) I roll to fourth. If I am in town I grab third.
On the highway I run in fourth till 45 MPH and then Fifth.
In the city I use third momentarily, (depends on traffic also), From 10 to 15/20 MPH. Then fourth momentarily from 15/20 to 25 MPH and ride fifth through town at anything over 25 MPH.
I use fourth on the highway to gain speed quickly so I don't hold up traffic too much. (big city, 400,000 cars on the road any day)
In town I shift up fast for lowest RPM and traffic moves so slow on the streets they don't really notice that I have no acceleration.
My commute to work is about 60% highway and 40% city for 14 miles one way.
I hope this help you. When I get my "Guino" installed (built first), I may change my habits. This seems to work best for now.
MetroMPG may have some better info. (He has more instrumentation than I).
