hey guys, just curious to know what the switch acturly does, other than giving the car more responce,
does it tell the computer to retard the timming and make the shifts a little smoother? cause in power mod by gearbox changes gears quiet firmly |

firms up the shifts, holds the gear changes a little into the rpm longer if you put your foot down. and turns a little light on the dash board

haha, i hardly put the foot down and it still goes right up to 4500 before it changes,l when my mate harley was driving he tried dragging a rodeo in econ mode and lost but as soon as he switched to power the car chanegd it's driving,
also anyone with an xr6 or ghia noticed around 1900 it starts to pull just that little bit harder? |

In the Mrs EF i6, I ensure the car is always in power mode as it shifts to quick when in economy mode, in my EB 5.0L I leave it in economy mode as the car easily gets away from other traffic when the traffic light turns green.

At 1900rpm that would be just when the cam is getting into its power range. The BBM wont switch until 3800rpm.

the power/econ mode is for auto gear changes only, econ mode shifts gears early at low rpm...
does nothing for engine performance... |
