Thanks Chris, very useful indeed. As you say, the model you posted seems fulfil most of the requirements. The only thing missing would be the effect of the AFR, knock detection and the composition of the exhaust gas. I guess you could fill in these gaps with a pre-calculated table of AFR vs...

Many thanks for all the comments, they are greatly appreciated. Just to clarify, I am not looking to write software to substitute any kind of physical testing. As I'm sure you know, after market engine tuning can be a tricky and potentially dangerous task. I am just looking to provide a...

Doesn't anyone have any idea? Even if someone could just tell me which division of Physics I should study, I'd be grateful.

Umm well yes and no. C# is an open specification so anyone is welcome to write an implementation of it but Microsoft only support Windows. There is a project to create a .NET runtime for Mac and Linux called Mono (http://www.mono-project.com/Main_Page) but the last time I tried it which, was...

C# is a language based roughly on C++ syntax but has been designed from the ground up by Microsoft. It has all the capabilities of C++ plus lots more. Some of the advantages are It's memory managed - no more deleting memory or memory leaks Cleaner syntax - No more pointers, unicode...

In a fuel injected engine the fuel is sprayed directly through the intake valve so the fuel will barley touch the intake manifold. The reason that the AFR is so low when the engine is cold is because much of the fuel won't be vaporized at the low temperatures and thus won't be burnt. In a...

In fact, I can make my question a lot more specific.. Given these variables :- Number of gasoline molecules Number of oxygen molecules Cylinder volume Compression ratio Burn time (spark advance) Is it possible to estimate the following outputs :- Pressure on the crank shaft...

There are a few options for doing GUIs in Visual C++ Express :- Use the raw windows API - The purest but most time inefficiant method see http://www.winprog.org/ Use a third party library like WxWidgets. See http://www.wxwidgets.org/ This is probably your best bet if using C++. But it...

I stared on basic then learned visual basic then C. I feel that it may have put me off if I had started out with C as you have to do quite a lot to get very little, especially with anything graphical. I'd vote for Python too then maybe C or C#. C is a dying language though, so if you want to...

I don't think you'll tend to see may companies starting new project in C or C++ unless they are embeded these days. Everything seems to be moving towards .NET mostly using C#. There is still quite a demand for script languages like PHP and Ruby but they don't tend to pay as much.

It all depends what your looking to do. If you just want to practice writing C++, your best best is to create a console application. That will just give you a main method which you can start implementing.

Hi Guys, I would like to write some software to teach people to tune internal combustion engines. More specifically, as some of you may know, an engine is controlled by two 2D grids or 'maps' which have engine load on one axis and engine RMP on the other. One map tells the engine how early to...
