sign me up!

i have a spare Gen 1 unit on the shelf from my audi A3..

so, we need to read one of these.. to later dissassemble the code and find the "key", so we can "login" and flash it over OBD.. and the issue at hand seem to be the FIRST readout iirc?
the rest shouldnt be much of a problem with some assistance and ASM knowledge.

i also have access to a Blue Gen 1 controller in my car, and my friend has a modified OEM unit with special code, made for a VW Bora v6 4-motion previously owned by the head of Haldex here in sweden.. (im thinking IF the Blue code dont work to flash in the stock units.. this other software probably will.. same same performance wise from what we can tell over here on the ice-tracks..)

Someone on vortex did it i'm not sure if it was through the CAN bus out of car or he was able to get the rom: http://forums.vwvortex.com/showthread.php?3959804-Haldex-flash/page5
 
Seems like the whole thing ended after he got the BIN file. A little odd but who knows what actually happened.

I'm trying to get my hands on one to see if I will be able to get a BIN through CAN with a dev board. If that's impossible I will take it to work and solder some wires to the board under a microscope so i can get at the rom.

How big is that board? It looks fairly large based on the components so i should be able to do it without any issues.

If anyone has a stock controller i'll buy it off you.

HPA are a few weeks away from the next batch of gen 1 interfaces, they are a inline piggy back system with a touch screen.


If i had a spare haldex id help.

a small update from Sweden..

Haldex have stopped selling the Blue Gen 1 controllers due to lack of hardware/controllers to upgrade..

BUT, they are now instead offering to update YOUR controller to the "new sport software" for ~60% of the price that a BLUE controller did cost a few weeks back when available.
(well, you dont have to buy the hardware now, which works out better for everyone)

Return time from sending in your controller untill you have it updated in hand, states about 1 week if sending within the country.


so obviously its 100% possible to flash the sport software onto ANY controller.. so basically.. one read = free Haldex controllers for anyone and everyone = more potential for further development like UM have done.

just thought id mention this  Smiley

Yep, first gen only


Quote
Included in the kit will be an LCD screen, cable/harness, and a connector that will "T" the link between the Haldex unit and the CAN-Bus (there is no Haldex module included; you will still need to acquire a new or used OE unit). 
 
This unit will allow variable manipulation of the Haldex system, the ability for the driver to choose and switch engagement control on the fly.

Well I again tried boot mode on the Volvo haldex that I have spare.

The controller works and responds to can comms.   I soldered 12v, ground, canh,  canl and kline and it all appears to work.   I verified the 256k eeprom is connected to the correct cpu pin.   Tried grounding it for 2-10 secs and no joy with minimon.   As soon as ground is released the haldex ecu instaboots into normal op mode and spews out kline traffic when I diagnose it over canbus.

Any ideas?

do you know which version of the processor is in there?
also i saw this "The pulldown must
be strong enough to force the voltage at the P0L.4 pin during reset below the upper VIH limit of
0.2VCC + 0.9V. On the other hand, it must be weak enough to allow the P0L.4 output to drive a high
level after reset."

recommend's 8K resistor

http://alt.ife.tugraz.at/datashts/Siemens/ap160701.pdf

this may be an issue

"Note that the port pins P0L.2, P0L.3 and P0L.5 must be at high level, and stable during and at the
end of reset otherwise the BSL routine is not started. The state at the EA input pin has to be stable
during and at the end of reset, too, to avoid unexpected effects."
