Got PCB, all the components and the new sensors today.
 
The sensors require a Gnd and 5V power supply input and then they have a 0-5v output on the third pin. So they dont work like a convertional pot where you can just invert the signal based on where you put the GND and 5v on the sensor. So the electronics main job is to read the sensor and then invert the output signals to the EAS controller for the one set of sensors.

So we can read the input from the new sensor manipulate the value in anyway we want then send the manipulated value to the EAS controller.

Theres a bunch of other advatages too. This board has a CAN interface. We already have a replacement valve block driver thats got a CAN interface too. So the end goal is we can completely bypass the EAS controller, while sending it fake values that wont cause error states.
One of the main very cool things is when offroad we will be able to level airbags from side to side in order to counter body roll.
 
Its one we developed for the P38. Theres connectors and stuff you need to chanage but its a "drop in" replacement for the stock valve driver pack.
 
How much ??

I have a couple of driver packs that have intermittent wires, but cannot access the PCB to resolder them. Tried digging out the compound but still cannot get the PCB out.
 
I’ve seen a few in the past make their own systems with success. One guy didn’t like the wiper arms so used magnets! Think it was PaulP38 did a lift with fabricated arms with threaded adjusters did some amazing things that guy well worth a read but probably not easy to find that stuff as internet has changed a lot since then. He did have a site or blog sorta thing iirc. @Grrrrrr will remember him
 
Marty experimented with his own driver pack, but apparently had issues with glitches due to interference. Work & family stuff got in the way of further development.

If it wasn't for that damn potting compound, the existing packs would be easy to repair.
 
No none. Its been running in my bothers P38 for about 6 months now without any issues.

This board also adds control for a second high flow compressor to be run in parellel with the standard compressor.

Now that i think about it we really need to do documentation for this board.

They do a system like this for disco 3 and 4. 😎👍

I have repaired a few. the potting is soft and not hard to remove, just tedious,

CAN bus, that finishes for me Crazy Automotive Network. I'm old school KISS technology. Off road is also not interest to me.

Thats exactly my point. Dunlop is the oem. If you can find them they work everytime and have the reliability that you are quoting.

All the other no name brands that you want to replace your oem sensors with are a very hit and miss if they going to work and how long they will last.

I repeat, Dunlop is just a brand name that can be stuck on any product for a fee.
 
I was digging this one for many days in spare time. Still cannot get the PCB out. Is there a trick ?
