RPM axis label in xdf - tunerpro calculation
Posted: Sun Mar 08, 2015 6:23 am
Hi folks!
First post. So far, all of the xdf files that I've seen have the rpm axis labels entered manually for each map:
i.e., label source > external (manual)
And then the rpm values are manually typed in for the row labels.
I see that the "label source > internal, pure" option allows for a conversion formula for the labels. Has anyone figured out how to write a formula so that tunerpro automatically converts the hex into rpm values?
My motronic (Porsche) uses the conversion:
hex: 4B 6A
where:
6A= (256-6A)*40 = 6000rpm
4B= 6000 - (4B*40) = 3000rpm
I believe that is the typical conversion for motronic. But how to code that into tunerpro?
Of course, I could enter rpm in manually too. Using a formula just seems more... elegant.
Thanks for the help!
ps- If anybody has a tip on how to figure out the conversion for temperature sensors into degreesC, I'm all ears.
