930 CIS, WUR, etc.-any books available?

Are there any books that explain the CIS, WUR, tuning, etc. FOR THE 930 MOTORS SPECIFICALLY?

I have a limited understanding of the fuel delivery system for my 77 930. And every time I read these types of posts, I'm convinced I could tune my motor for optimum efficiency and power if I had a better understanding of the information. I've read alot of tidbits about CIS, WUR's and fuel pressures from posts on this BBS, but I'm just not getting the big picture.

The extent of my "tuning" has been limited to adjusting the AAR and setting the CO%. Then for the next month or 2, I have to adjust the idle to compensate for a high idle at low oil temps (through warm up) and a low idle at high oil temps/traffic situations.
I'm convinced that my WUR has a problem.

I'm thinking of purchasing an LM-1 system so I can get the basic information I need from my motor (under real driving conditions)to do this correctly.

I have the factory manuals, am I missing something?
Any tips?
