FW: [W126 Coupe] functional spoiler?

[Shayegan, Richard]

DUH, what am I thinking, the 500 and 380 have CIS, not CIS-E...that
improved index for the cd manuals tricks me up cause it has a few bad
links.

And isn't there even less on the CIS-E (which is what AFAIK the 500
has)?
  

I thought the 500 had a memory-mapped mixture control (chip)?



Couldn't the same be achieved by turning the fuel mixture adjustment a
little clockwise?
  

No, that would set idle but when the system goes closed-loop, the O2
sensor sets the ultimate mixture. You would have to somehow put a small
voltage in series with the sensor to make the mixture look a couple of
tenths (air/fuel ratio) too lean, and the FI would compensate by going a
little richer.



There is no 750-om spark advance control resistor on the CIS-E though,
right? AFAIK the only way to free up more power from the CIS-E cars for
close to free is the advance the timing like 2 degrees with a woodruff
key, right?
  

I have no idea, learning what my own system does was hard enough. Get
the Bosch book and see what the 500 uses, and how it works. I thought it
used a memory-mapped protocol (see above).
