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!

Full version or free version of winols?

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.

Demo version.. I wish I had the full version.

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..



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.


The goal is for the ECU to see the change, yes.


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..


It's called google. ;)

If you have the free win

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

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


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


You cannot "move" an axis in winols. You can only tell winols where axis data is.


That question makes no sense.


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 (,) = ?
 

What?

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 ..  ::)

Good luck with the exam..

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

me? you mean the % = load thing? or you tellin hinxx?

hinxx's definition..

Gotta work on that understanding/definition then .. can you share yours?

http://s4wiki.com/wiki/Load

8), thanx!
So far I've been on http://s4wiki.com/wiki/Bosch_ME7.1 only. I will have to visit more links on s4wiki, probably many times.

Unfortunately a lot of it is crap :(

I only really regularly update the Tuning page... a lot of the other content is very old and/or inaccurate..

Edit: Replied without noticing there's a Page 2 of this thread.  :D

He's telling hinxx that load is not a percentage of possible engine output.

If I'm not mistaken, load is a product of a couple of calculations, but essentially represents cylinder filling percentage.  100% would be the maximum amount of air (charge) that would be contained by the cylinder at normal atmospheric pressure.  In a forced induction application, you're compressing more air into the cylinder, and this is where the additional percentage comes in. 

As an example, 200% would be twice the amount of metered air than would be allowed at normal atmospheric pressure. 

Please correct me if I'm wrong, but this is how I've understood it.

Can anyone teach me how to scale an axis?
I've read this and it seems that an axis has to be searched in the bin file and cannot be specified??

You can change the axis to whatever you want , you just have to be careful you have found the correct axis for the map you want and you don`t change something else instead.
Also look out what other maps share the same axis with the map you want to alter  ,so you can change them too according to your new axis

edit: I hope it makes sense my English are #$%^&

Got it, finding e correct axis is e tough part.
Thanks for the tip  :)

Use an already  defined .bin and work with it.
Usually Maps with shared axis are the same.

After changing axis you should rescale column that you`ve changed.
Best practice is to take care of last 3 columns
Let`s say KFMIRL and you want to rescale up to 7500 rpm (stock for 180PS is 6520 for example).
last 3 values in rpm axis are 5520, 6000 and 6520
We will get rid of 6000 rpm row.
So you need to copy 6520 row to replace the 6000 rpm, change 6000 axis to 6520, change 6520 axis to 7500 and then recalculate each value of this row.
My example is never used because mostly the load is rescaled, but that was a quick example.

Also, you can rescale load axis. On my file max load on KFMIRL is 95, on other files is 99. But after changing KFMIRL you need to rescale KFMIOP to match your new KFMIRL.

But like other guys said, you must know what you are doing because some maps share axis, so if you change load axis on KFMIOP for example you need to rescale your KFZWOP(2) too.
And if you change that load you should change all axis related to load in order to match new max load.

For begining i recomment you stay in standard axis limit. For my stock file my max LDRXN is 147, but all my load axis are scaled up to 160 and 166 load
