Well, it sounds like it's more of an issue of lacking the understand of what a standalone ECU is and does in general (which IMHO John shouldn't be held responsible for teaching you). Most of the parameters to be changed are universal across the ECU platforms with variations in designation, scope and range. But in general, it's pretty much the same base knowledge area and you expand from there.
Example: AEM's infinity use VE base tables as compared to Nissan's fuel based tables. That is something which IMHO John shouldn't be responsible for teaching you. There are a multitude of ECU manufacturers who have ZERO tutorials or support. John has an ample amount (which is all available through his website for free, which I will stress again). Nismotronic was my first standalone ECU, and with Johns tutorial, help guides and support, I managed to sort through several vehicles on my own (2 of which are dedicated HPDE/PDX vehicles and have not blown the up as of yet (knock on wood)).
John's tutorials are fairly indepth and are quick to get anyone started. Also, his Help library is fairly extensive if you take the time to look through it (which again, is FREE through his website).
Again, IMHO John provides the necessary information for just about anyone.
Below is John's help library. I hope this will get you started. Also, John has posted several videos on youtube for your viewing pleasure.
Nismotronic HELP for all your needs!
Goodluck!
