[W126 Coupe] EHA Valve

[Jonathan Hodgman]

To some degree...I've found using a stand along 5 wire A/F meter that these
cars are lean in stock trim and that adjusting the EHA as mentioned does
change it for max power.  In some cases I've found cars running as lean as
16-17-1 @ WOT and cruising @ 15.X.
Fiddling w/ the EHA got WOT down to 12.X and cruising around 14.X.
