Hello!

I just want to say THANKS for yet another project that brings free (as in "freedom") knowledge to people.
A year ago or so I began to feel interested about cars, how they work and how people can make the industry more "free". EFI arose then as a naturally interesting question, since I do software development for a living.
I do share a thing or two with Rusefi's main contributor - e.g. my obsession with clean, readable and easily manipulable code
Who knows, maybe some day I will be able to contribute to Rusefi!
So far, I am satisfied by getting to know this fantastic site.

Welcome and thank you for your warm words!

Hello Dan (from Europe)

Welcome and pleasure to hear from you. Have you found the wiki? You might find this page about the simulator on a PC interesting. http://rusefi.com/wiki/index.php?title=Manual:Software:Simulator

What kind of software guy are you? Seems there are many different flavors, some are embedded, some are higher level GUI guys, and other are hardcore Linux guys, with a larger variety of paradigm's to choose from. Do you have any particular area(s) of interest?

Rather high level. Programming is just a thing I do for a living. Java, some C and C++. I am interested in maths and model theory too. But I am not very knoledgeable on it yet.

At the moment I am having a look at the basics of EFI (theory, engine-agnostic).

Btw, is it just my impression or there is a lot of secrets and closed technologies in this area?

I would say not so secrets, just too many little details to consider to get things right. The whole fuel combustion in cylinders with pistons is just over-complicated for us digital people, too many little effects to consider makes the whole voodoo magic of getting it right.

I think @megatroneye meant that there are many after market ECU's out there which are closed technologies. These closed technologies have many secrets.

There are many closed efforts out there, and they have lots of reasons for wanting to keep them closed. For closed efforts, a bug could be hidden and you would not be able to prove that they had faulty equipment and you would not know that things failed because of their faults. That's important from protecting the business plan and cash flow. Cash flow is important as it allows for budgets to do regression testing, and to get test mules do to this regression testing on, etc. So they commonly can minimize the bugs. Both open and closed efforts have strengths and weaknesses. I personally want to know what's happening so I like Open efforts. I get to learn lots of interesting things, many of which apply to other ECU's.
