Why would you need to do that? The z axis of tables is always the output of the table. Have you looked at the FR yet? If there are other conversions/scaling to be done, they are described in the FR.
Unless you are referring to the fact that the ACTUAL value stored in the ECU's memory (8 or 16 bit) isn't actually an infinitely precise floating point, and must be represented as a fixed point integer.... which is an entirely different discussion.
This terminology is NEVER used for a reason. Sensor voltage is converted to a lambda value. Depending on the sensor, the conversion is different. Same with MAFs.
Sensor voltage is sensor voltage.
After it is converted to different units (g/sec or lambda or AFR), it no longer has the "voltage" units.
Thus it is NEVER referred to as "lambda voltage" or "g/sec voltage", which would be confusing because there would be no way to know if the person is talking about the resulting (calculated) lambda value, or the actual voltage coming from the sensor.
It would be properly referred to as "O2 sensor voltage" or "MAF sensor voltage"
I meant to say lambda
sensor voltage, please excuse my typo. I see how this was confusing.
yes, I have read the me7.5 FR once. I know I need to read it again as you always miss stuff the first time around but my questions are in regard to interpreting the values on the maps using WinOls. Alot of the time while searching and examining maps I cant find what the z values actually stand for. (thats why I wanted to know if the z values of the map pic I uploaded(on pg3) were actual lambda values or the sensor voltage) That info isn't in the FR afaik.
Another thing is that a big difference between me7.1 and 7.5 is the implementation of the wideband 02 sensor. So what are the differences going to be in the maps that the both EMSs share? or do I NOT have to worry about that and just manipulate the maps as I see fit? Now that I know the z value is for sure actual lambda values I feel I can confidently change the map to what I want.
Sorry if I'm a pain in the @ss, I just want to understand and the S4 wiki doesn't explain everything (in some instances it raises more questions... NOT saying it sucks by any means!) and the FR prettymuch explains how everything works inside the EMS and what coincides with the maps and such. It also only shows what the x and y values are (maybe I missread something and missed where it shows what the z values are suppossed to be?) I dunno
Before I ask a question I look for the answer in these references and throughout the nefmoto forum using it's search box. Unfortunatly, there isn't a section in the forum on how to use WinOls or Tuner Pro including how to properly interpret the values that show up in the maps, or a legend of map axis symbols to values conversions (ex: %=load, U/pm=rpm, V=volts, z value of 1.0079=1.0079 lambda, etc) or which definition files are compatable with what versions of WinOls, or how to generate definition files, or how to locate maps in the hexdump without a definition file, or establish a new map previously undefined in a definition file.
A section with this info I believe, would be a nice addition and would clear up alot of confusion. Too bad I don't know the answers, otherwise I would write it up.
edit: typo
