slight high rpm when going out of short slope

Post by ular_king on 2012-08-15, 11:29 pm

Hi guys!

Newbie here just collected my wife's white XTR 2 days ago...just wanna check with members here if this is normal behaviour of a dual clutch gearbox.

We live in a condo and have to park our cars on multi storey car park. U tend to rev slightly more when going up a short slope and i noticed that right after that the rpm maintain at 2k and above and you can hear high rev like stuck in low gear after coming out from a slope on a flat road at less than 20km/h for a couple of seconds. Is this normal for fiesta?

Sorry for the long winded story....hope members here know what i meant........

Rgds,
Ular_King

yea I think it's normal for how this gearbox is mapped. I don't find it a problem as such, though it probably wastes a few drops more fuel haha

Same here on my sedan version, it when to 3,000 rpm (on a flat road after slope) before shift gear and can hear the loud engine. I think it will goes up more if not because of the protection mechanism.
Try this trick, immediately or after the slope press the brake (no need fully press just a bit). Then press the accelerator. Make sure no car behind, else kena bang at the back.
So far only happen in my office car park area, which has a up slope and follow by a corner. It does not happen when going into the car park.

thanks

The slightly high revving of the Fofi when coming out of a hill and onto a flat surface is a normal characteristic of the GB. As our car is able to detect that we're going up or down a hill gradient, it will adapt by holding the gear so that we don't lose power while going up. So the first few seconds after a hill, it rev will be higher before adapting to the flat surface again.

The button that you describe on your gear lever is called the Grade Assist. When switched on, the gears will be held longer before switching hence higher revving. As some of you use it for the extra boost of power, it can be used when going down hill as well by providing more engine braking. Smile

Waa...

then the Grade Assist will be really usefull when going down hill at Genting Sempah, rite?Laughing

Is it similar to Over Drive function?

Yes, it will be really useful going down slopes like Genting Sempah. It can be used going uphill too if you find that the GB is shifting gears too much, with the Grade Assist on there will be less gear hunting.

Yep, it is similar to the Over drive function where it locks out the last gear, hence higher revving and more torque. But keep in mind use sparingly unless you want more engine noise and higher FC. Rolling Eyes
