I'm looking for help identifying the alum. box under the hood of my 85 SL380. The name on the box is "ProgRama" Made in U.S.A.. Replaces MB0025452632/Bosch 0227100042.

I suffer from a rough idle (pro stock rattle) but it holds great at 600 RPM. At speed it seems to pulse when driving. I am wondering if this should be replaced with factory.....not even sure it could be part of my problem.

That unit is the Ignition Control Box, used for the engine igntion system(spark). It will not cause a rough idle. Check spark plugs, air and fuel systems.

ProgRama is a company that rebuilds MB control units for engine, climate control, and other systems.
