the one i did find on youtube is horrible..
I have alot of questions like:
What do all of the possible map value symbals mean? % = load, u/min = rpm, etc.
It will take you some time to get familiar with the expressions, acronyms and symbols that are used in this area. There is no magic that will make you understand it over the night. Search, study, read, ask, compare, ... There are numerous automotive books out there that will get you started.
If you got an answer about all possible symbols in one post, it would open up a plethora of new questions, it is like a snow avalanche, questions will beat you up till you give up! What you should do instead is to try to understand small bits at a time. Where to start? Anywhere..
Consider this one:
RPMs - engine revolutions per minute, example 0 - 5000 on diesel, 0 - 8000 on petrol engines.
% load - how much load is imposed on the engine, 0 - 100 %
Now you've got your (partial) answer, but did you not also get several new questions at the same time? Crazy, I know.. Now consider that you are flooded with hundredths of silly little explanations like this..
What are the steps to change the axis of a map?
If you are talking about the step-by-step guide , let me know if you find one
The reality we have is that all it comes out of experience and understanding what, where and why needs to be done. And that road is long and hard. Additionally it is way more to tuning than just changing few numbers in the ECU.
IF the axis is moved or changed, is it only for our view on the maps in WinOls or will the ECU "see" the maps differently if the file is flashed? or do we make the changes we want to the map then move/change the axis back to where is was?
The goal is for the ECU to see the change, yes.
Is scaling a map the same thing?
There are several approaches on how to "tune" the map, in other words change some data values that are part of some map. One is changing the values in the map itself, another would be adjusting the axis values, sometimes you need to even modify the map size, extreme stuff would be combinations of all the above..
Is there something like the S4wiki for these kinds of questions?
It's called google.
