in this example im using a 173 BIN file with software number 1 267 355 705. im using WinOLS to look at the raw data and see where the start address is for the axis data tho if u know what ur looking for u can use any hex editor for this.
here is what im starting with (note: RPM axis has been edited in the file im using here so wont be the same on yours but will still be the same start location in hex). ive calculated the RPM points and manually entered them into the XDF parameter info for this map which gives me this:

to set for automatic axis info on any 173 BIN file with the WOT ignition 1 map in the same location u will want to set the label source to "internal, pure" which will then allow u to add the location of the axis info for this map which is shown above in the blue part at the bottom of the picture above. once u add the start address of the axis info then set "data size" to 8 bit and set "address step" to 1. if u then click apply u will end up with this:

this is now displaying the actual axis data that is in the BIN file as u can see above.
the only part i do not know yet and am hoping someone here will be able to help with is coming up with the conversion equation to calculate the axis data into RPM. it looks like it will require creating additional arguements in the XDF parameter info but im not sure how to do this.. it will need to have an equation that subtracts the axis data from 256 starting with the "86" located at the highest RPM end of the map and then multiply it by 40 then for the next axis data point down from that it will need to divide the current axis data by 40 then subtract the current raw axis data from the sum of the previous equation and then multiply that by 40 to give the second points RPM value and so on untill u reach the lowest RPM axis point on the map.
anyone have any idea how to create such an equation?
for an explanation of how to calculate RPM points from RPM axis data see here:

for other axis data the equation will be different, u multiply the sum of each axis equation by 40 here for RPM value but for temperature or whatever other axis information u will have to add/subtract/multiply/divide by whatever it is for working out that axis data in relevant units for the axis in the XDF.
