Default GZ20 Acceleration, OD/OFF, ON, PWR, ECON, what to use?

Hi,

Just want to get some opinions for those of you who have GZ20 Automatics.
What Combination gives you the best acceleration and shifts. Some suggest turning OD/OFF. What about the PWR, ECON settings?

Use PWR for acceleration . I have a modified trans now though so I don't us it.

As for Overdrive don't worry about it, only comes into play as '4th gear'.

Well for a bit of spirited fun,

i put it into 1'st hold the brakes on, with a bit of throttle to get a bit of turbo pressure build up, then flat to the floor and brakes off, then to 2nd' when getting a bit high in the rev's then usually going 300km/h by that stage!

ahh love the auto 1G...

Hi, If you pay for my parts I'll do it

I've just been experimenting with how the box behaves with the ECON, PWR and OD/OFF combinations.

ECON gives better acceleration from about 0-60, but power gives better response and acceleration in the top end i've noticed.

Would having OD off give better response when driving at higher speeds? thats what I've noticed.

It should, as you are in 3rd gear, O/D on would be a bit sluggish but better and more economical cruising.

Thats just how it feels to me maybe its not true but it feels that it shifts when it should instead of revving it out too much before shifting.
