Can someone post a pic or vid of you changing the axis on a map in WinOLS please? It seems this is talked about alot on the forum but not really explained how to do it right and I'm confused and don't want to screw anything up! Thanks a bunch!

God i hate instructional videos on youtube.

zzz waiting for dipshit to get to the point.

give a readable document any day of the week.

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.

What are the steps to change the axis of a map?

 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?

Is scaling a map the same thing?

Is there something like the S4wiki for these kinds of questions?

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  Wink 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. Wink

There are two portions to a file image
code (microprocessor instructions)
data (maps, values)

Typically, in winols, you will only be changing the data.

What are the steps to change the axis of a map?

You can't move an axis w/o rewriting the code. You can tell winols where axis data is stored in the binary though.

That question makes no sense.

No. The assumption is that you already know the basics of EFI, control systems, and computers.

Well, my first question is: Why did you WAY overthink the answer to my question? lol
 I understand what % is thats why I put "=" next to it and then typed "load" Same thing for U/min...its rpm. I ment for the rest of the symbals for values that show up on the maps. Like: (,), Is there a legend of somesorts that shows what the symbals mean? I know % = load, u/min = rpm, but (,) = ?

Thanks for the clarification about axis data. Since you can't move an axis I see why some of my questions are not valid.

My question about scaling though should be answerable. Which, it has nothing to do with the map axis? In the near future I will have to change values to compensate for a larger MAF housing, this is where my question about scaling came from. I thought it had something to do with the axis info or something.
 What I gather about scaling is just changing the map data to a certain extent so that the ECU isn't thinking one thing while the sensor is saying another. right? I found a thread in here somewhere about how to scale the MAF maps according to the housing size but don't remember where I found it. It def won't hurt to read through and find it again though..

I do know the basics of EFI and computers, control systems is way too general of a statement though. I have read the 1.8t FR, my computer skills are well above average ( I think so anyway..hehe) as I have been going to college full time for the last 2 1/2 years, working on 3 degrees in assorted computer related subjects.(network security, foreignsics/intrusion detection, programing and general computer skills). Much of my computer knowledge came from experience before my formal schooling though. I've been playing with engines since I was a child, mostly NA engines allthough forced induction concepts are not hard to understand. I'm 32 years now.

My questions were geared toward using WinOLs exclusively. Using this program is new for me.  Usually the first question that comes to mind while checking out maps is: What do the values stand for that show up in the table? (z values?) They don't seem to be labeled all that well so I end up guessing and thats not good. Hence the Q earlier about what the map symbals stand for.

After Monday I will be able to use my extra free time until the Fall '12 semester starts up to play with WinOLS, I'm currently studying for the CCNA certification exam. Monday is the assessment.

Thanks again for the clarifications nyet.

1) reread the maf article in the s4wiki
2) reread the tuning article in the s4wiki with the FR in hand

A philosopher in me took over control of keyboard .. plus I kinda misunderstood the question about the units ..  Roll Eyes

Good luck with the exam..

BTW your definition of load isn't quite right...
