Haldex Performance Controller

[catso]

Anyone know anything about this? Presumably alters the drive split between Front & Rear, any good?

Was a guy on www.tyresmoke.net recently decribing his experiences with it.

I rang AMD yesterday and had a good chat with one of their guys about it for my S3.

I'm in!

I think Forge do something similar

Forge *used* to supply a unit with a switch to lock the Haldex in 50/50 mode. This is not what this unit does. This unit doesn't rely on wheel-slip data before putting torque to the rear - it also looks at how hard you've pressed the loud pedal. I fitted the unit from Haldex a few months ago and am very pleased with it.

Did you fit it yourself? if so is it an easy DIY option? do you need any special kit to programme it or anything? From reading various reviews I'm starting to like the sound of this unit and might 'need' to get one but can save around a couple of hundred £'s by fitting myself.

Does it really make the handling better, if so how?

You know it makes sense

[clived]

Catso, I went to AmD for fitting, before they were running their "buy one, get it fitted free" offer - doh!

However, it does come with fitting instructions (which I've seen up on the web somewhere...) and from my memory of them if you're competent, it doesn't look like a hard job - but then it shouldn't take a garage long either...

Handling is certainly more nuteral when pushing hard.

Had mine fitted today, to early to report on what the major difference is as I also had other things done.

BUT, I have noticed a constant whine coming from somewhere in the rear, not very loud but definitely noticable. It doesn't change pitch at all (with revs, car speed etc.). Anyone else had this too? I was too far from AMD to turn back, will ring them in the morning.
