Computer for Opel GT 1.1 Liter SR engine

"Computer" for Opel GT 1.1 Liter SR engine. This is the one that controls the mixture during deceleration for the two carburetor O.E.C.S. engine.

That's a relay coil. This "computer" counts the RPMs and is supposed to open a solenoid valve mounted on the intake manifold between the two carburetors, when the RPMs are above 1800. The valve allows manifold vacuum to open a diaphram valve. This provides a richer mixture during deceleration to prevent mis-firing.
Sounds like the engineers got a little carried away with their design (I probably shouldn't talk, since I find myself doing the same thing at times). Remember KISS (Keep It Simple Stupid, right?)
Anyhow, just more things that can fail.

Got it. Interesting setup. Actually pretty high-tech for the time, but as you say, maybe a bit of "design overkill"
