What does this box do? Detroit S60 14L 2008 bolted to intake manifold...

Please see attached pic. What does this box do?

I'm thinking of converting my DDEC VI intake to a DDEC V one because the EGR on my truck has been modified and I want to keep everything looking stock. This box would have to go because it can't be bolted to the DDEC V intake manifold.

 

Well. It's complicated. I live out in western Canada where every truck is deleted. BUT I'm going to doing flat deck work in the maritimes and out there, I'm told that nobody will work on a deleted truck. Furthermore, forget about ever getting a valid MVI.

So, I can spend $4,000 fixing the EGR including getting the software fixed OR I can bolt on a few DDEC 5 parts and keep everything looking stock for about $1,000.

If the box is gone, it will look stock.

Do you know what that box does?

 

OMG ! This is exactly the kind of information was I looking for. Doser valve.

I read a lot before making my purchase and everyone talked about how good the Detroit Series 60 engine were. Come to find out that my DDEC 6 engine is the worst one ever.

What kind of MPG were you getting and what kind of work were you doing with the DDEC 6 equipped truck?

 

4.5 to 5 mpg. I hope that my engine gets at least 7. I'll go broke with that kind of mpg. Is that with the EGR modified?
