Something wicked this way comes...

General Owners Cars

John will correct me on the bits I’ve got anything wrong, but the electrical system is a work of art and VERY trick.

The Motec PDM (power distribution module) removes the need for any fuses or relays throughout the entire car - you tell it what needs how much power and when and what to do and it takes care of everything!

Because you can set it to take commands from any button or combination of buttons, it vastly reduces the number of switches required. IE If you wanted the start-up procedure to be ‘a quick dab of the horn, followed by a long dab of both light switch and screen washer, followed by push of start button’, that’s what can be set. And if you want ‘ignition on plus push of the starter’ to result in hazards, horn and fire extinguisher firing up, that can also be arranged! Or if you want a starter button to become the horn button when the engine is running, no problem.

A ‘real life’ example of how that would be useful is say a racer comes in for a driver change, you can configure the PDM/ECU to say ‘the moment the air jacks are released select 1st gear and give it 4,000rpm for three seconds’.

ECU, PDM, dash and on-board cam all chat to each other so whatever data the ECU and PDM is receiving (vehicle speed, brake pressure, steering angle, throttle position, revs, boost, temps, pressures, g-force, wheel slip etc. etc) can all be displayed on the dash and/or on video play-backs.
That data can also be read in data logs.

Very nice in-car adjustable brake setup.

23

So essentially the whole car loom is new? Even lights via the PDM?

You using their trick new CAN switch panel?

Look forward to seeing it at a London lotus meet (ace cafe??).

24

Complete new loom yes. The one in the car was 12 years old and had a few interesting amendments through its life.

By the time it had the bits and pieces added, in the places we wanted, it was more expensive to modify than start from scratch. Plus the new one is 2/3rds the weight, has a dedicated engine loom plug and has Raychem wire throughout, so more flexible, deals with heat better, etc.

Haven’t got the switch panel that they do, as couldn’t find one that looks good, is the right size and had the correct switches required. Settled for some new light switches and two column stalks from an early Astra, that had cruise control on one stalk - 3 extra buttons - and the multi function display control on the other - 2 extra buttons. This will allow us to change maps, turn on launch control and generally control all sorts of stuff!!

Crikey, I’m happy if mine just starts in the normal way. Nice colour by the way!

26

A more ‘real life’ example would be to rig up GPS to limit the speed on the A55 :smiley: Or rig up an SMS interface so John can set the boost from the pitlane :smiley:

Will be JSR’s own version, I have put these on both my Exiges … really good set up

29

Ey up Andy, has the boat come home yet?

30

Perfick timing :sunglasses: … boat landed last week and today it was released out of customs so now SSC have to get it passed and stuff … I just have to find a car park that it can get it into !!

31

Fantastic, Andy :sunglasses: You’re going to cause a right old stir driving the black beastie around Sydney. Any chance of some pics with iconic locations eg bridge, opera house in the background?

32

+1 on the photos - an upmarket versions of Birds custard just to prove it’s there ! :smiley:

Can you get a photo with the Elephant’s Douche?

33

Rob, Oh yes - gotta do those for sure, I will get Jude to boss everyone out of the way to get the best shots :wink:

Just for you Steve I will try and find custard, but go to Kings Cross, are you mad ? I could get shot :wink:

35

I remember getting properly drunk in Kings Cross in Sydney, when I was out there for a trade show. ahhhhhhh those were the days. haha

36

You mean the days when you actually worked Sean? A long and distant memory I would imagine!
