I have question about my '08 SS. I have noticed, under the hood, there is not any type of cover over the BCM. Pictures of non-SS HHRs show a BCM cover.
Is there a reason the regular HHRs have the BCM cover and the SS's has no cover?
Will the regular HHR cover fit on a SS?

 

I think you mean ECM. I would say it's not needed.

 

I bought from "Race And Street", was as they described, "HHR Fuse Box / BCM Cover Plates - Polished". So, maybe their describtion is incorrect.

If I purchase the black plastic ECM cover from a regular HHR, will it fit my SS.

 

Got a buddy with a HHR? Do a test fit.

 

Since computers are heat sensitive, I'd be disinclined to install any covers that might affect the ability of the ECM to cool itself.

 

What I don't understand is why the regular HHR's have a cover and the SS's do not. I guess I'm a quizzical kind of guy.

 

Maybe higher under hood temps with a turbo ?

 

Sounds logical to me.

 

SS uses a different ECM than a regular HHR, AFAIK

 

Maybe....they just being cheap
