DODGE 2012 HO CUMMINS Hello everyone. It appears the forums are not as busy as they once were. I was hoping to create this forum for owners of the 2012 Dodge 6.7 HO. I believe this will be a good place for owners of this rig to share tips, tricks, service manual links or anything else related to this year specifically. 2012 HO, 4x4 4:10 gears, auto.

Yea. As of today I had to drop my sub-level again. Getting to smokey as summer time started coming on and noticing more and more smoke as I would be towing and/or launching with a heavy foot. I'm wondering if others have notices anything like this with warmer weather? No ill-effect to MPG's at all but the smoke level is slightly higher now than was during the winter time. I'm also wondering is the injectors changing for like a break in process and flowing more? -
Evening Gals and Gents, Having Issues with my Scangauge. It doesn't report load(LOD) correctly. It's showing 0 LOD at idle. This results in 0.0 GPH at idle. I have contacted Scangauge and am currently emailing with them to hopefully find the problem. For those of you with a Scangauge what do you show for GPH and LOD at idle? How is LOAD calculated? I can even see 0 LOD when TPS is greater than 0. I found this out while coasting downhill in neutral and slowly pressing throtle down. I do have codes stored: 0622, 0743, 1595, 1765 I believe most of those codes were related to the Mystery Switch Lockup control Other Known Problems are Alternator VAC to high(cycles between 0.065-0.156 at idle) Thanks! Currently running a 2002 Ram Cummins 2500 Quad Cab Automatic. Mostly stock except RP-100 and edge programmer.

Can anyone offer a suggestion as to why my fuel mileage is so poor, I have played with several different tunes on my quadzilla and still can’t get over 14 on the highway. I’m running 35 in tires. I’ve heard it could be injection pump but it was replaced not to long ago and it’s been running great so it’s hard to believe that’s the problem. I’m also on stock injectors

Since @Me78569 and company have the tuning thread for performance side. I'm going to start the ecomony and MPG thread for the Quadzilla Adrenaline. I'll be posting up my MPG logs and all data I can provide of what I've got going on. I've been keeping hand math logs of all fuel purchased as well as my tablet running OBDII link LX and data logging from that direction too. I'll share my tunes and settings as well.

hey guys n moparman, first post here i just got an email from the site suggesting my return but ive yet to post anyways ill start off with a bang.. 01 24v dodge excab 4x4 stock new vp n raptor, 86mph 2250 rpms i think forget what its governd to also have a 12v anywho pedal to the floorboard 13 psi going to the pump. idle i think 14 -17 im pretty sure. im trying to do this from memory i havent driven the truck in a week or so. so i believe it gets good FP? the gauge is taped into the shrader valve on the fuel intake banjo bolt and i recently changed the fuel filter and saw no change in numbers... regardless the truck gets 11-12 mpg around town. litterly $100 or about 22 gallons of diesel goes 250 or less miles...horrible i have 17* of timing in my 97 12v n it gets better mpg. on the bright side...winters rolling around and my coolant temp gauge is pegged on 140 and that truck doesnt get warm for sh*t...is it as simple as a stuck thermostat? im a 12v guy i no nothing about vp44,obd2... all i no is the map sensor also went in this truck and it was close to $500 no one could get it but the dealer so i dont want to have to buy anymore sensors and such...i would like to sell this truck, but of course i want to get the kinks out. thats why im here pickin you guys brains, see what we come up with. Also i dont know if this forum offers a for sale section or not i havent looked around much but i got a decent deal on this truck i believe so if anyones interested there might be another good deal to happen?! thanks all. ps- i did not proof read. -
I have heard people talk about fuel millage being in the 20's and maintaining the ideal 1800 +/- rpm, but iI run down the road at 55 mph @ 1500 rpm - 70 mph @2000 in overdrive, 55mph @2000 rpm with overdrive off.In order to keep @ 1800 rpm i have to run 45 mph with overdrive off or 65 mph in overdrive.I am running 305/75/16/10 tires 32.6 in tall with 3.54 gears, would changing to 4.10 gears help. I had factory size when i purchased the truck which was 265/75/16/10 or 31.8 tall and was about the same.I am getting around 17 mpg now but diesel just hit 3.99 gal and gas went down to 3.21 gal Most of my driving is hwy, very little stop and go.I thinking of upgrading to 4 in exhaust (have stock no muffler now) and rv 275 injectorsANY IDEAS ?????

I went aliitle bigger on my tire size stock was 245 75 16 went to 265 75 16 just wondering what my actual mileage would be right now im doing a little better than 14 arond townon the new tires also will the scan gauge 2 allow me adjust the tire size?

Took my truck and trailer (trailer rated for 14000kg) and drove 3.5 hours to pick up a backhoe attachment, drove back. Filled up and checked my mileage and was very dissapointed to see the result! 11.6 mpg

Alright Mike, not trying to prove you wrong but I want to figure this out.You say cold IAT drop MPG big time on yours.You say Winter Fuel drops it.So why is it that running winter fuel with no winter front whatsoever at 25F ambient at 70mph, do I get the same 21mpg (actually 21.54mpg) that I get on a 100F day? I get consistent mileage all year, summer or winter fuel, rain snow sleet or hail. I know everyone here seems to have this "it's winter fuel, so it's ok to see 2mpg loss" but why am I not seeing this loss! I am thinking if I could figure this out, I could help you all not get a loss either. -
$3.29 per gallon at my usual fiiling station. time to run 10% waste oil..Ops

She runs like you anit never seen, boys I am going to be hitting 19 mpg I just know it for a 9800 lbs truck. It runs so smooth you dont even know it's running, sounds like a electric car it's so quiet. 2 Years of misery man finally over, next I be hittin the rollers LOL.Sorry for all the excitement, I just cant get over it's finally done. 1 Million miles here I come. Well only 750k left to go.

Ok guys I have 315-75's on my truck and I believe that my mph is off about 13% so if i am trying to calcuate my correct mpg would i take my total mpg' per tank and multiply by 13%??? :shrug:If i am thinking right this should give me an accurate mpg. Any help is much appreciated.

i have a coworker that has a 07 3500 that is bone stock. he has just under 100k miles. he was complaining that he gets real poor fuel mileage. he said his best tank ever was 14MPG but is usually 10-12 empty and ~8 when pulling his cattle. he said that it doesn't have the power it did new. he was thinking about buying a used bully dog programmer. i warned him that he needs a EGT gauge before he starts adding fueling enhancers. i also suggested a compression test.also his tires were "loosing" lugs on the inside of the tread face. they were a Hankook off-road tire. i thought it was because using a off-road tire on the highway, but it was only the inside lugs. like every other one was finedoes anyone know of anything i can tell this guy?

Well gang... I've been playing with theories and ideas for long enough now its time to put them into a design and see if it actually works. We all know the 24V's seem to take a good tumble in MPG's as the winter sets in well ISX proved that with the 12V engines with static timing that MPG's don't change. Well if you look at it the only thing that could be tossing this out the window is the IAT sensor on the 24V is changing the VP44 performance. Most know that colder air produces better HP/TQ because colder air is denser and requires more fuel to keep balanced. Well if you reverse this and warm the air (in theory) the VP44 should retune and burn according to the manifold temp. So what I've done tonight is fished through my resistor pile and found 3 I'm going to use for test candidates. Orange - White - Red - Gold = 3.9K Ohm = 116*F IATRed - Violet - Red - Gold = 2.7K ohm = 132*F IATRed - Black - Red - Gold = 2.0K ohm = 148*F IAT So now tomorrow I'm going to pull 3 test runs on the same piece of highway... Seeing if the highier the IAT temp increases the MPG or not... I'll can give you something to think about... Grid heaters are NOT controlled directly by the IAT... With the 2.7K Ohm resistor in place before even starting the grid heater still where hitting as normal. So there is more to the grid heater that the IAT temps... ... On the cutting edge again...

ok....I know I'm running a lifted truck with 315 tires and 4:10 gears but doesnt 13mpg still sound really bad? 120 miles of the 200 i just drove was highway at 57 mph. the rest was in city and some extended idling for warm up before driving. also, my exhaust manifold is cracked...but I don't know how much this would affect it. What do ya think?

I am a newbie here but I have been reading for several days and most everyone can only get maybe 18-20 mpg out of a 24v. Trying to figure out how my truck gets such good mileage. Can get 24+ with a steel Knaphiede bedcover that wieghs 1200#. I AM NOT COMPLAINING!!!!!! Just trying to figure this out... No electronics on truck. tires 245/75-16LT 3.55 auto

Hey guys, new to the forum. I have a '98 Dodge Ram 2500 Cummins 5.9L 24valve automatic 2 wheel drive 3:55 rear axle ratio. I have done literally everything I could possibly do to my truck to improve the mpg. Yet, I cannot seem to get anything over 15-16 mpg in the city and hwy can vary from 16-22 mpg. Current mods are afe cold air intake, airdog 100gph pump, rv275 injectors, smarty tuner, 4" straight exhaust, IAT fooler, scanguage 2, tires are toyo m-55 245-75-16 filled to 80 psi. The truck would get 15 mpg city/hwy bone stock with a 3" exhaust however when the fuel pressure was tested I was told that it was at 9psi at idle. I'm wondering if its done damage to the already weak vp44 I seem to see other 4x4 trucks getting 18 mpg city as for me doesn't matter what smarty setting I am on or how much timing I give it if I really baby the heck out of it I can maybe manage to pull 16 possibly 17 city hwy mix. I'm planning on changing my diff oil to amsoil 75-90 same weight as I have in there now just hoping the amsoil will help also running 5-30 amsoil in the motor with a bypass. What could be causing the mileage to be so low? Truck shows no signs of starving for fuel I have the airdog set at 18psi now but if damage has already been done not knowing how long its been running 9psi from the PO is there any test I can do without having to pull the whole pump out? -
My overhead read about 16.7 to 16.9, but actual mileage was only 14.2, on stock size tires. Most driving was short trips and basically no highway miles. I know that's not TERRIBLE numbers but I am hoping to get up there around 17-20 mpg if possible. I was using the overhead to adjust my driving style and it seemed the harder I accelerated (to a degree) the mileage went up, so I would try to drive it harder, I think this tank I will ease up and see what happens. But other than that, I need to fix a small fuel leak behind the motor. I think it's the stock return line but haven't pinpointed it yet. Some ideas of future upgrades are AFE Stage 2 intake, RV275's, maybe a larger intake horn? Besides that, all pumps and fluids are fresh, so what else can I look into for mileage and performance? -
ok changed the injectors to rv275s from dap and mileage got a little worse:banghead: was running 5x5 than tried 3x5 now trying 2x5 the comp is tapped maybe time to untap but ill wait and see how this tank reacts went from about 15 to about 13:banghead:
-
trying to tweek the settings on the comp. with the added rv275s had it on 5x5 mileage went down now trying 3x5 any thoughts on this? ps yes im keeping my foot out of it as im trying to get this mpg thing in line thanks:thumbup2:

Been checking my fuel mileage since I installed my 2nd hand motor and running 60-65 been getting 15.2 pretty regiously. (I need to up date my weight on my sig. but anyway I weigh around 11k.) Getting 14 pulling trailer 7k. My best was 16.3 driving 55-58. Now that is stock everything except 5" exhaust and BHAF.Today I put my DDP50hp injectors in and we'll see what it does. I now this eng. is a lot quieter. Next I will put EZ back on. I can say this stock s----

Sister graduated yesterday and somehow word is out that I know how to play with diesels and a guy hit me up with his 24V saying he wants to give it a tune up. This means set his valves (apparently has never been done, ever, after 160k miles) and check over some other things. I imagine being a 24V I should clean his map sensor and what else is there to check on those things? Now the thing is he went from 18 when new and has dwindled down to 12, I would think if his valves and sensors were off/dirty it would constitute the drop but what other things is there that would cause this? I don't think he has any codes or anything, just never had any maintenance done in it's life out of neglect.

Hello everyone, im new in this diesel world, as well on this forum, im having trouble with my 01 3500 dodge 24 valves cummins 4x4 dually, im getting only 14 mpg on highway, the only error codes that im getting is the 122 (apps low voltage), could the apps be the reason of mi really low mpg's?, cause im getting a timbo's apps next week.Thank you guysGreetings from Mexico
