I was hoping it was a simple ratio, with the two values being the numerator and denominator of the ratio - so in effect a percentage change factor. But as suggested by
80stech, there may be some other mechanism here I have yet to discover.
The simple ratio used in the e46 is easy to follow (thanks to
TerraPhantm at e64 fanatics): -
0x25 = 37(dec)
0x23 = 35(dec)
37/35 = 1.057, or a 5.7%
But is seems our e53 is more complex and BMW love to store simple values as complex sets of integers. I'm try to figure out what they have done here in the e53 (or at least on mine - I'll get the version of the IKE next time I connect up).
I'm going to have to get setup with NCS Dummy to get a dump of the module functions and to confirm the hex locations. I have NCS Expert but have never bothered with NCS Dummy - now seems a good time.. :-)
