I messed with advancing & retarding the intake cam. Basically, leave it alone. The car idled like crap, and either had power down lo and nothing up top, or vice versa. The Motronic had no idea there was a change, so the ignition maps were all off, and my mileage also suffered. Leave them where they are is the conclusion I met.
I could send it to you. I think I am going to machine a nice one from some 1/2" aluminum bar now that my garage is a machine shop. This sheetmetal one was not perfect and left a little to be desired, honestly. It worked though.
