I'm willing to extend an olive branch in the form of shared information if you (whoever) is willing to admit that you really don't have a clue when it comes to engine tuning, and in particular as it relates to electronic engine management as is used in fuel injected gasoline vehicles.

As dangerous as it may be, I'm a believer in shared information and individual experimentation. I think that if some of you had a look at the code that runs in the engine management system that there would be a great many revelations, which should move forward every discussion of engine efficiency, to include the use of BSFC maps as this thread is supposed to be about.

(I'm referring to sharing a file such as those I use as a reference, - a copy of the binary code that runs in the ECM converted to hexadecimal as it was used during programming.)

It will also become clear that there is a big difference between knowing people in high places and actually knowing what is going on in terms of engine function.

If you are comfortable working in hexadecimal, or programming in machine language then the file will be easy to read. For others you can use the commented text provided, and if you wish to verify function you can learn machine language and trace it out. For further verification of function you could set up a test bench with an ECM running the same code and perform functionality tests (several tuners use this method), or you could use a working model in a running vehicle, using datalogging software to verify functional changes.


I am a human though and have my pride, so the next move needs to be the retraction of some of the statements and claims made thus far, and an honest willingness to learn. Short of that, there's no reason for me to post more in this thread.
