Данных по халдексу по прежнему нет.
Надеюсь помогу тем, что нашел. Но скорее всего на базе вашего контроллера не получится. Для испытаний лучше всего иметь халдекс на столе (как голландец ниже делал испытательный стенд) и смотреть влияние ваших сигналов на открытие/закрытие управляющего соленоида. Еще одна проблема - подружить ваши сигналы с сигналами от ЭБУ в блок халдекса.
Механика работы насоса в халдексе зависит от версии халдекса.
Здесь пытались разложить сигналы на блок халдекса 2 (на его соленойд, который управляет насосом):

Вот некий даже выложил как он делал управление (путем прямой подачи тока ограничивая рестистором):
this will allow everyone
to select the desired ratio manually since you do not have to connect it to the ECU via CAN Bus. Без подключения к ЭБУ по кан, подменой сигнала.
There are some steps you need o do to make it work:
1.- Find one pin that has continuity between the 8 pin connector and one of the terminals of the solenoid valve ( I don not remember 100% but I think it was the earth).
2.- Add a new wire from the other terminal of the solenoid to pin 6 that has no use on the module connector, now you are able to put any signal directly to the solenoid using this 2 pins, modify the harness for the controller or get a new connector to make your harness.
3.- Use a relay feed 12v to the Haldex pump take a signal that shuts off with the ignition switch, this way the pump will run constantly but will shut off whenever the car is off. If you wan to cut the current to the pump whenever the brakes are on, add another relay with signal from the brake light and that will stop the pump when you press the brake pedal.
4.- To feed the solenoid valve I just put 12v in series with the resistor to limit the current, the one in the picture is one of several that I tested you have to find the one that works right for you, use a current meter to find the resistor that keeps the current between 0.4 amp to 1.2 amp. This range is what determines the opening of the valve and thus the percentage of clutch slip 1.2 amp will put 100% lock on the clutch pack.
5.- Also using a boost switch (from a meth injection kit) to cut the current to the solenoid will allow you to turn the AWD on or off based on boost, as soon as the turbo is producing boost it send the signal to the solenoid. Currently mine is at 0.8 amp starting at 5 psi and works just find no wheel spin when using launch control.
I think you could use some sort of PWM signal instead, you just have to try different values to find the one that let you control the valve in a similar way. I think you could feed the solenoid using a resistor that limits the current to the max value, 1.2 amp will be the max current when you give it 100% PWM signal, also a high frequency may work to modulate it from 0% to 100% to keep the solenoid valve steady at the desired position you want.
Здесь было продолжение где пытались этим всем делом управлять путем шим (но что-то не задалось):

Наиболее продвинутые блоки сейчас продает этот:

Тут же у него режимы работы описаны.
В любом случае тема крутая. Если у вас получится что-то сделать, это будет фантастика.
