2014 Overland Ecodiesel with chip + cold air intake

Hello folks,

I bought a 2014 jeep, first new vehicle for me. I subsequently researched the best way to get the maximum mpg without sacrificing power/torque.

I added a Race Chip tuner (set it to eco) and an AFE Cold Air Intake with a bluetooth OBDII scanner to reset any CEL codes that might pop. None yet.

So far I'm averaging 42mpg on the highway going 67mph. 27mpg city. I drive like I stole it in town, so I'm happy. I'd easily get 30+ if I drove like Grandpa.

I just took a screenshot that I'll be happy to text anyone of my OBDII scanner that shows HP, Torque, PSI, and such. It maxed out my Torque at 500+ and HP is 325 with 22psi.

And the cold air intake from AFE sounds awesome. You can hear the turbo spool up, and sounds lower rumbling at idle.

That's all. I hardly ever post, mostly troll, but I figured someone needs to post something like this because I haven't seen anyone else do this.

Feel free to chime in if you've found a better combination for mileage + efficiency + fun.

I hate that we can't post pictures without uploading the file to a website. Don't have one, and probably won't take the time to add one. Message me if you'd like me to text you more info. Happy trails.

Re: 2014 Overland Ecodiesel with chip + cold air intake

I'm gonna take the troll bait here but there is no way you get an actual 42mpg at 67mph on flat ground sustained. That would mean you can get thousand mile tanks, ain't happening!

Sorry to say, but you don't have 325 hp either. Certainly not at the wheel, nor the flywheel. NO plug in box is going to give 85 hp, especially set to Eco.

This thread is so far from the truth it's laughable!

I hope the above link works. I'm a greenhorn using online photo sharing sites.

Using Dash Command, a reputable OBDII scanner. You can see the arrows that point to the highs reached around 20psi. Torque = maxed out 500+ and HP around 320-325.

Being new to the forum, is it normal to have posts attacked as spam without offering the original poster a chance to post evidence? I don't usually engage in online debate, but I refuse to have my evidence-based post ridiculed or scoffed at.

Why not post evidence to disprove my claim instead of questioning the authenticity?

Thank you for reading. I'll update with a screenshot of my realtime mpg and average the next time I take a road trip.

You can't measure HP and Torque electronically. It takes a Dino to measure these. Sorry to burst your bubble.

Re: 2014 Overland Ecodiesel with chip + cold air intake

Actually with the technology now a days yes you can measure hp and tq with out dyno.


And autos don't have a flywheel technically. It's a flex plate.

Re: 2014 Overland Ecodiesel with chip + cold air intake

Color me intrigued. I'm a big fan of mpg with the diesel. So if you built a better mousetrap I am all for hearing about it. Have you confirmed based on your own mileage recordings and fill ups. I would be more interested in hearing what you record from fill ups versus mileage traveled in your own log in case it is just a computer error. With that kind of verification I'd definitely copy you. My only reason for being skeptical and not trusting your computer is it sounds too good to be true, though I hope it isn't.

Interesting. However, given the information coming across the OBD-II link and the fantasy values for fuel economy and boost that the Torque app comes up with, I'd say the burden of proof firmly lies upon those making claims of surprising results from what amounts to a BlueSpark (et al) linked to a tablet app. We've seen repeatedly how BlueSpark/Banks Bullet results in EVIC's algorithm becoming deceived and reporting falsely high fuel economy, and this product seems to use the same basic approach. Some of these other reported values in OBD-II apps are derived calculations as well.

Manually calculated fuel economy per tank and dyno values would be much more substantial evidence than an app screenshot.

BTW, welcome madi!

I don't think your post is Spam and apologize if you took it that way. I think you are trolling and all your claims are a false.

Local speed shop says you'd have to prove that Bring your gadget and compare it to the actual mechanical readings.

Re: 2014 Overland Ecodiesel with chip + cold air intake

I recently plugged my iPod v1.0 into the OBD II and noticed a line of code that limits boost to 5 psi and after I changed it to 20 psi I was able to achieve 50 MPG. Two days later my Jeep transformed into a Prius. Terrible.

Re: 2014 Overland Ecodiesel with chip + cold air intake

Well....I'm new to this Eco-Diesel platform....just picked up a 2015 Summit for the wife this past Monday. I guess the HP and Torque claims could be taken as values at the crank...but at the wheels??? The fuel economy numbers must be coming from the readout....hand calculated would be more realistic way.

There's no doubt that these modern turbo diesel's can be tweaked to make some amazing torque and HP. But looking at the Race Tuner website.....reads like a fueling box.....raising fuel rail pressure. Big gains are found in actual tuning along with other modifications. I'd be concerned about the emissions package with pushing a bunch of extra fuel and not adjusting other engine parameters let alone the emissions side of the equation.



My latest "Tuned" truck gained about 2-3 mpg on the highway if I do my part and conditions are just right. To get 10+ additional mpg's seems "Above average" in terms of what even high quality tuners ( individuals and companies) of diesel engines advertise.

Best of Luck,

Wayne
