How do you determine the best shift point?

How do you determine the best shift point?

By examining how each gear curve intersects it’s neighbor, you can reasonably determine the best shift point by locating which gear yields the highest torque at any given speed. RPMs entered below must be listed in order lowest to highest, any values beyond the highest that remain set to 0 will be ignored.

What is the perfect gear shift?

The perfect shift means that the engine revs match the new speed of the drivetrain perfectly, so that all you notice from this shift is a change in the sound of the engine, but no rocking in the drivetrain. If you want to use your engine as a brake, do it, after you have shifted down and released the clutch again.

Can you change the shift points in a transmission?

Changing the shift points in the transmission will do nothing for the giddy up and go off of the line. What you can do with shift points is make sure that the transmission shifts to the next gear so that the engine is starting out in the next gear at about 300 to 500 RPM before maximum torque.

What’s the best way to use shift points?

What you can do with shift points is make sure that the transmission shifts to the next gear so that the engine is starting out in the next gear at about 300 to 500 RPM before maximum torque. That way it will have a ton of pull from maximum torque and then work up into maximum horsepower.

What are the three rules of shift point tuning?

The first two rules are fairly obvious. The third rule is needed to avoid the case where a vehicle shifts up, the RPM is reduced in the new gear, then the vehicle shifts back down, starting an infinite cycle of up and downshifting.

What causes a car to shift to the up shift point?

Once in the lower gear, the vehicle might have enough torque to accelerate to the up-shift point, causing the transmission to shift back into the higher gear again. This is normal behavior and there is no way to completely avoid it in a vehicle that shifts automatically.
