    M54 Cruise Control Functionality

    I've done some searching but haven't come up with a ton of conclusive information on this topic. As stated in the title, I would like to retain cruise control functionality when going M54 from M52. What I am unsure on is how to get the DME to be happy w/a e30 vehicle speed output. I have a non-ABS car, it is worth noting. Some people seem to just code out VSS, but it is very much necessary for cruise operation. Doing some research, guys doing S54 swaps are using an interface from a Z3 to make the cruise stalk work with the DME, which appears to work for the M54 as well.

    I am doing my own tune and have TunerPro configured. Any input is appreciated!

    It should be pretty much the same as this:

    the main difference is in the DME, where the settings will be different since MS42/MS43 don't have the same parameters as MSS54.
