Nice.
Have you been able to write to ecu yet? I did not manage to find correct minimon settings to write.
Is the blue controller based upon software LSC ECC 0011?

Offtopic and crap
Perhaps someone with standalone in a really light car could have some use for it, but if they somehow managed to do percentage control of regulating valve with piggyback it will burn the haldex clutch pack quickly. Some part of it could be fake too since I doubt haldex ecu are reading any can packets with percentage of requested torque transfer.

just sharing knowledge on what people are doing to make more use of these units. the aim here is to be able to read and write the haldex ecu.
speaking on read/write. my current unit has an issue (dtc on abs stating no communication with haldex and constant tac tac noise for haldex). i have constant 50:50. this is no issue as i have another haldex assembly and diff to replace. Note: my car is 1999 a3 quattro. i dont even have haldex fuse like other gen1 cars have. i can donate the unit once i replace it if it helps someone here

I have spent far too much time messing with Gen 2 and 4 Haldex controllers over the last few years.
The info on this thread really got me off the ground regarding dumping them.
I have dumps of pretty much every Gen 2 and Gen 4 unit ever made, if you need files just ask.
But my question to anyone that might be able to help, is what is the security login pin code for a Gen 2 Haldex unit e.g. 1k0907554?
Does anybody know?

don't get me wrong, i am 100% guessing. however, i am able, to a point, to control the haldex pump V and pwm.
this results in different behavior from the haldex controller as seen in the logs.
i really do not know why the calibration adjustments result in the way they do. i do not think the map being modified is = pump V exactly.

Found some interesting text on this Gen 2 file. Not sure what it refers to. |

On the Gen5 controller the checksum is just an Add16. In order to read/write the newer controllers you need to write a loader or vr_read. I can help if someone wants to upload a G5 full read so I can solve the seed/key.

You have a Gen 4 or Gen 5 read ? |
