HDC target speed is throttle position controlled. LR designed it that way. If you want to drive faster than the minimum target speed, then the HDC will prevent the vehicle from exceeding it. I've tried it many times and it works as I described. It's all in the owners manual. It's a cleaver system that works in conjunction with the driver.
Not sure it's something I would ever use. Normally cover the brakes on downhill if needed. I wish they had of reduced the speed of hdc instead. Even when dropping from 6 to 4.4mph that's still 2 meters per sec downhill which is far too fast on a 30+ degree slope. When I've taught peeps to use it oft road it's always been with caution due to speed.
 
Had one as my first car, still have cos im a sentimental **** who doesnt get rid though i might be breaking it soon. Only got retired cos i couldnt get it mapped on a 4wd rolling road after tuning and putting in an emerald ecu.

Learnt a lot off the k series... Still learning as it seems due to a few silly mistakes made on my girlfriends freelander today.

But i do love the engine. Cheap and easy enough to work on. Love it so much it was me who persuaded my girlfriend to get her freeby after selling her ****ty fiesta.

The amount of cars ive seen people spend more money on than id have ever needed to on a 1.8 freeby! Granted thats because ive learnt to do the work myself but a lot of other cars go wrong too. Her old 2006 fiesta had the thermostat housing seal go twice!

Looked after, theyll be one of the best cars you can buy.
 
Just been reading the previous posts regarding freelander turbo.

Ive been thinkimg about a vvc / turbo hybrid in a freeby for a bit now. Will be experimenting with this engine in my rover 25 first. However many on the mgrover.org forums have confirmed emerald will easily run this combo. The emerald ecu will also relay whatever info is needed back to the abs module so hdc should still work.
 
There's a two way communication to the ECU I think? Also I am not sure how the ABS ECU will handle the lack of communication to the engine ECU as a fault code, but there is a turbo Freelander running - presumably without HDC faults?

Great project I think! :D
 
Yes, Mark can certainly do that. You need to change the crank sensor to something that is more MEMS3 friendly - but not too difficult.

What Mark, I suspect, won't have experience with is how the Freelander communicates with the HDC. Something to discuss with him. If HDC doesn't alter the engine map in any way, this may not be a problem at all: put in new ignition and fuelling maps and leave the rest alone. :)
 
BUT you'll need a different MEMS3 ECU to the one currently fitted in your Freelander: the MEMS3 in Freelander won't have sufficient device drivers for the turbo waste gate for example. The ECU to get is the one from a Steptronic MGF or TF.

In other words, it'll be a biggish job for Mark to get the turbo MEMS3 working on the Freelander. Not impossible I suspect, but quite a challenge.

It might be cheaper to go the way Skinny Mike did and use an after market ECU.
 
Maybe - worth a chat with Dave and Karl at Emerald to see how a K6 can be integrated into the FL CAN bus

From what i read he's already done a freelander or two...
