In following the 1.8t community thread there is often mention of rescaling maps and axes. While I think I have a general idea of how to go about it, I thought I'd ask in this section to see if anyone had a nice how-to example as it may alleviate any confusion for others who may have the same question.

For example, if *cough* someone *cough* is using a CH file for a 1.8t and referencing it against a TT CA or CB file for something like LDRXN, KFMIRL, or KFMIOP values, but the rpm axis don't match up (ex. 480 rpm vs. 600), how would one go about correctly changing these values? I'm fairly certain that just changing the values in the axis wouldn't do it as the factor would be off.

I think I understand.

So, for example, I am looking at LDRXN with a factor of 0.0238438 for both the CH and CA boxes. If I'm reading what you've described correctly it would be no problem to change the rpm values of the CH box from to the CA box rpm values of as well as the corresponding load values, without any concern. This is true for all maps that do not have a preceding axis, which is shared with other maps.
Other than referring to the FR, is there a simple way of seeing a preceding axis?

Thanks much, DD!

This sounds like a better way to me as well, only I don't feel like I have a understanding of how to best go about it. Do you happen to have any examples?

Best way to find out what/how many other maps share the same axis as the map your modifying?

Thanks, D
