Prado Cruise Control Problem

Definately not cable Phil. All elecronic.

That's what I do. When approaching a hill I click the criuise control off, accellerate slightly before I get to the bottom of the hill, and click the cruiise control back on when I get to the top.

For some reason you can use a particular throttle setting going up a hill and the transmission won't kick down, unless you're using cruise control.

Yep......this is right.....

Combination of low horsepower at low revs (tall top gear - 2200rpm @ 100km/h) means it can't hold the set speed even at full throttle. The auto has no option but to kickdown since thats how its programmed to a full throttle event at that road speed.

I guess if we would also complain if it didn't put enough effort in too :)

Getting an engine chip apparently helps, however it will need to be a pre-ecu type (Ditronic) rather than a post ecu type (DPChip) since the later uses a wire attached to the throttle to measure the intended load request to add power over standard engine output which the cruise can't provide since its all electronic.

The lighter you are the better behaved it is, but the heaver you are the extra effort in changing gear quickly can also be handy.

It would be nice to have a 2 mode system, so you could set it to "lazy" mode where it would cruise at 100, but under a certain amount of throttle it would aim for 95 or 90, but return to 100 when the road was flat again.

Anyway, its annoying, but not much I can do about it, I'm much happier with the tall final gear ratio than the cruise issues....
