I posted earlier about milage dropping from 14 to 9 after the dealer worked on the truck. wvchaddox asked if the dealer perhaps turned off MDS--From what I read, MDS wasn't available until 2006, so I don't think mine was equipped (though I did buy it while the 06s were already out). Modification Update: After the K&N, I saw ~0.5mpg increase. After using the Hypertech max energy, I can see and additional ~1.5mpg increase. I say "can" because it appears to be much more sensitive--which makes sense. If we attempt to drive as conservative as possible, we get a definite improvement over stock, but drive slightly more aggressive, and there isn't any difference from what stock would do--indicating that the fuel maps were probably designed to increase power when needed, then save energy when not needed. So, it's improving, but still doesn't fix that step change after the dealer worked on the engine/computer. I think my next step will be the o2 sensor. Any other ideas?Thanks, Ron |

Replying to: kipk (Dec 16, 2007 12:34 am) It is a Ram 1500, 2 wd, 4 doors with the SLT trim and the 4.7. I’m not towing or hauling anything. It’s just me riding to the shop and then around town doing errands and I weigh 150lbs. Before the Ram I had a 96 F-150 6 cylinder and I would get around 15 - 17 city. On my way home from the dealer I was getting 18 – 19 on the highway running 65 – 70 in the Ram. I’m driving like my Grandpa and can’t break the 9.0 level. Thanks, lss

Replying to: badd63 (Sep 26, 2007 8:51 pm) Or even a fuel line. I have fuel economy problems that were as simple as a fuel leak. If you can smell gas, you have a leak. I could write a story about how hard they can be to find. Or forget to connect - or properly reconnect - some sensor wiring. If is is connected to the wrong place, tracing it out against the factory manual may be required. Or maybe knock something loose accidently. I know - have done it to myself more than once. A USAF electronics tech I worked with many years ago used to say, "Just look where the last GI screwed up." Or something like that.  He fixed a lot a problems. Rule #1 for trouble shooting - Make a GOOD inspection. This includes GENTLY tugging on connections in addition to visual. Key word is gently. Too much enthusiasm and you will generate way more problems that you fix. I understand that many new computer control modules need to be re programed in the field. If the wrong firmware was loaded, it could possible the computer thinks you have a 6 cylinder. If no firmware was field loaded, it is likely running factory test software. Find out what version(s) of firmware should be loaded, than have a shop (different shop, of course) read the software load version for you. Compare the two yourself. If you just ask, "Do I have firmware load XYZ?" a lot of people will say, "Yup" because they have no clue how to read it out or just don't want to bother.. Also, some of the toughest problems I have encountered have multiple causes for the same symptom(s). Don't stop your inspection just because you find something. Check everything - twice! Rule#2 check power. If the first computer was diagnosed as bad, it may have been operating incorrectly because it had bad power. I have fixed a lot of electrical problems over 50+ years by merely cleaning the battery connection. A shop can not charge enough to afford to stay in business cleaning connections, so they sell you a battery or computer. I would replace the battery cables with the best quality ones I could find before I spent anymore on aftermarket fuel economy upgrades. Hope this helps. |

1998 Ram 1500 Quad Cab 4x4 5.9L Auto Stock gearing. I get 10.9 City using 87 octane. No mods to the engine with 265/75/16 tires. I never drive on the highway since my work commute is 10 miles from my house. We got some snow the other day and driving with 4x4 100% of the distance to where I was going only affected the overall MPG by .2MPG. But that might be due to driving slower and with caution. I love the truck aside from its DodgeISMs. Bad steering and bad transmission (knock on wood my tranny is still working fine). I am going to get a DSS steering kit to fix the trackbar issue.
