spoke to awesome gti today and found out you can get a replacement ecu for the haldex clutch that gives you 40/60 permanent 4wd same as quarto. They told me totally changes the drive! the French rally team use them so cant be that bad. Anybody here got one or have any experience with one? Would anybody else be interested may be GB they cost about ?500. 30 min job to fit any feed back would be appreciated thanks lee

I know that there are several different Haldex controllers you can get, each having different characteristics. They are made by Haldex themselves and are a straight bolt-on replacement.

Quite a few people on forums.vwvortex.com seem to have fitted them to their R32s. They aren't a 40/60 split but are simply more aggressive at diverting power - i.e. some slip will cause more power than standard to be shifted to the rear. As is normal with Haldex, you have to be pushing quite hard to notice the benefit of the power shifting rearwards. And, they will always disengauge when you brake.

There was a video somewhere on vwvortex of a guy taking his R32 round a circuit. He had a supercharger and the haldex ecu fitted. Car seemed to have no understeer and was even oversteering out of bends.

Awesome told me it gave 40/60 split permanent 4wd looks like it wont be getting then unless it is proved thanks mate

 

[spanner]

It may well give 40/60 as I believe there are different controllers available. It's just some of the Americans are running the aggressive clutch.

It's probably worth contacting Haldex themselves and asking what products are available.

I believe the one Awesome use is actually 50/50 split (could be wrong) but there was a thread a few weeks back discussing this..

AFAIK the general consensus was that with it being PERMANENT 4-wheel drive that there was going to be considerably more wear and tear (and therefore increased repair bills to expensive drivetrain parts, not to mention rear tyres) and that they werent designed to operate under full load 24/7, I.E the Haldex working flat out all the time to deliver power to the rear wheels...

 

[blackburn]

thought that might be the case as it was not meant to run on 4wd all the time its a pity they dont do a switchable one so you can turn it on and off.Suppose it is ok for a rally team to use as they strip the car after each race and have a lot of funds!

Vortex's search engine is working again, so I found a couple of links to information on the ECU. The first one has a few graphs showing the torque transfer difference from the standard unit.

Okay....I've got a bit into this now. Found another really good post on this on vortex:

If the hash reference in the URL fails, scroll the page to the post with a big picture of a Haldex ECU and read the text below it. It answers some good questions about how Haldex works.

This is the part that we sell:

[EddyH]

Ade, how much are you selling these for and what sort of GB price could you do?

 

[awesomeade]

?499+vat at present - but i wouldnt be able to offer any group buy discount on these since we're selling them at a discounted price at the moment - US retail is over ?600! so in the near future our retail will be over this amount!

US retail is over ?600!

Not according to the neuspeed link you posted. They have them listed at $900.

Do you know if these work with all Mk4 based Haldex equipped cars?

 

[awesomeade]

yes 900 USD translates to about 470 GBP + import charges etc - our usual retail should be around 600

Not sure, all i know for sure is they fit the 4motion/R32/TT Quattro

 

[EddyH]

I think it will fit mine then if it fits all those.

I thought most of the import duty was VAT but you're adding VAT on top or are you saying your usual retail would be ?600 inc VAT?

 

[EddyH]

Just checked and the HPP/EIP supplied one will work on my car.

 

[spanner]

I'm really tempted to buy one of these as I reckon it should have a huge grin-factor.....but I also want a Milltek as the dreaded R32 drone is getting on my nerves on my daily M5 commute.

Aaarrggghh decisions, decisions....

 

[Reflex TDI]

Yeah Spanner but the Milltek ain't on offer is it?? []

 

[EddyH]

I've been in touch with EIP and they've come back with the following:

Standard price is $900

Single orders from members of this forum get 10% off

10 or more orders gets us 15% off

20 or more orders gets us 20% off

I'm awaiting confirmation of shipping costs and details of the shipping agent so I can confirm import duty costs.
