Detroit S60 EGR/ Fuel Injection Upgrades

[Capt._Chaos]

I'm driving a 2004 Freightliner Century C-120 (Crete company truck) with a Detroit EGR engine, and have been severely disappointed with its overall performance (bad fuel mileage- 6.2 overall, and little or no idling, and I'm on the cruise most all of the time. Also very low power for pulling the hills).

Has anyone had an EGR/Fuel Injection Update done on their late-model Detroit engine? I'm curious as to what to expect once mine gets this work done. How does the engine perform now as opposed to before?

From what I have read, this upgrade consists of an updated EGR valve, replacing all 6 injectors and the wiring harness going to them, as well as some changes to the ECM's settings. Is there more to it than this?

My company has asked me to take the truck to the Stewart & Stevenson Detroit dealer in San Antonio during my time off to get this done. I sure hope it improves the performance of this gutless EGR watermelon!

Note: My International that I sold this past summer had an older Detroit that was averaging 6.7 MPG, and had a LOT more pulling power than the engine in this Freightliner. Sure, this is a company truck that has been "castrated", but I know it's gotta have more power than it does.

Jeff I know what your saying, no power..I have a 1998 Int 9200 with the DD 430 hp. all the power I need but was a dog. I know they(shop) fixed the problem and it is a raging Bull now..I can see about this and let you know, I am sure 6 years though may be different..

I get avg. 6 mpg and I am happy as I idle,and run hard so I am not complaining..

My Classic with an S60 averages about 6.5 MPG with my Proheat. Some days, shes acts like she doesn't want to pull with an LTL of say 9000-11000 lbs. Then, I'll get the backhaul of 42,000, and she pulls like there's no tomorrow. Gremlins, I swear.............

I recently bought the Nexiq Pocket Diagnostic link so I can hook her up to my laptop and keep good tabs on her.

I recently bought off ebay, something called Detroit Power Fittings. They appear to be a Canadian Detroit Diesel Part and may possibily be a marine use item (cause the seller was a marine Detroit Dealer). According to the instructions, the power fitting replaces the "factory restrictive fitting located on the back of the cylinder head fuel return gallery." Supposedily, this fitting adds power and performance that the factory fitting restricts. It cost me $50.00, so we'll see.

I soon as I install it, I'll let you know what difference is (if any).

I got my truck back from Detroit Diesel in San Antonio and have put a couple thousand miles on it so far. They replaced the injectors, injector wiring harness, installed a larger fuel line from the transfer pump t the fuel inlet port on the back of the cylinder head, and did an ECM reprogram.

There is an improvement in pulling power, but the fuel mileage is still pretty bad. Then again, I've been traveling out west in the mountains since I left home last week.
