Re: who wants to port to Power Architecture?

It looks like they made some major updates to how it worked based on user feedback.

Also the ability to do DI injectors means it may work for my PD TDI project (if I ever get to that).

Re: HOLY GRAIL Builds

HHO is different than H2. HHO is often considered an assist not a primary fuel. Similar to propane injected diesel. H2 is a very good detergent so it is very hard to get longevity. Oil just doesn't stay where you put it. However HHO is typically just an assist so your normal lubrication mechanism's...

Re: HOLY GRAIL Builds

I've mathematically shown it in the past to never work.

This is a snake oil/perpetual motion device. The only way to get any appreciable H2 into a cylinder is to carry H2 along for the ride. You will never generate enough to run an engine on what you generate.

Re: who wants to port to Power Architecture?

I believe the best approach as it stands now is to use one of the A20 chips eventually Olimex will release this SOM at a reasonably low price. Looking at the specs on that it doesn't look at all like a good MCU. It looks more like a good general processing computer. http://www.allwinnertech.com/en/...

Unfortunately CAN isn't deterministic (FlexRay will be) so CAN is best used for communication of non-realtime information.

Re: CAN bus

Keep in mind that you might have 2 if not 3 CAN busses. The drivetrain will likely be at 500 kbit or 1 Mbit. While there is another one that runs at 250 kbit that controls windows, etc. This is how VW is set up. From this it looks like the MiniCooper might only have 1 with most things being on K-bus...
