Unhappy Anyone benefited using a "Performance" MAF Sensor or Chip?

I have a '15 Pilot AWD, considering installing a "JET Performance" MAF Sensor and a NITRO Performance Chip to enhance MPG & Power?

I have 31K miles on it and I'm getting an ave. of 15/City & 20/Hwy (if I use the Cruise-Cont'l most of the way...), most of my research indicates I should ave. approx. 17 & 22??

So, has anyone benefited using any sort of "after-market" parts as mentioned to get more favorable results? As with all my cars in the past, I have already installed a K&N Air-Filter.

Additionally, I have had good luck with previous cars; (Infinity, Lexus & BMW), using a combo of a K&N filter, JET MAF Sensor and a "Performance Chip"[/I][/B] from various manufacturers, to obtain decent MPG and Power increases...
Another thought I'm considering, I have had to use Premium Unleaded gas on all my previous cars since 1996, wondering if that may be a factor as well?

Any thoughts and advise is much appreciated!

K&N Filter risks getting oil on the MAF element if you aren't doing a clean & re-oil absolutely perfectly. In other cars, we've seen more crud under the K&N that under a pleated paper filter too. Nod goes to pleated paper unless you have the throttle all the way open at high RPM's. The rest of the time, the throttle is the controlling restriction to engine airflow.

Your Pilot uses an array of exhaust gas oxygen sensors to trim fuel mixture, after initial guidance received from the MAF. A "performance" MAF will have little effect on mixture, as any changes it makes will be trimmed back based on the measured exhaust CO component. If the "performance" MAF slots in where the factory piece lives, there will be no change in airflow either. Unless there's something magical, save you money.

As far as performance chip, go for it and report back your results. In my limited experience, the only available parameter for the chip to adjust is ignition timing. To get the performance boost, you'll need to buy premium fuel to protect the engine, or enjoy the knock detection system pulling that spark advance back out as quickly as your performance chip tries to put it in.


Want better fuel economy? the factors that affect mileage most are diametrically opposed to "performance". Enemies of fuel economy are the pedals. Drive like you have a raw egg under your foot in your right shoe, with gentle throttle inputs. Brakes are death on mileage, since they waste all the kinetic energy you've built up, turning into useless heat. Think about driving like you have no brakes -- anticipate traffic speed changes far enough in advance that you can avoid using the wide pedal until the car has slowed almost completely to a stop on its own. Preserve that inertia, and you'll need less energy to bring the car back up to speed. Also, do everything you can to keep the car in top gear with the converter locked, with the engine spinning as slow as possible in that mode. Think 48-55 MPH and that gentle egg-filled shoe. AC is off unless it's needed too.

My car gets slightly better fuel economy if I fill with premium fuel, but at the current low fuel prices the percentage improvement doesn't justify the percentage cost increase. Using regular, My trip computer says I'me getting an average of 24.5 MPG in local driving. The calculation at the pump is about 1 MPG less than the computed value. Highway use only, like on our little Thanksgiving jaunt to the bay area, showed 27.5 on the trip computer, and again about 1 MPG less when calculated at the pump. I keep the tires at the recommended pressures, use synthetic oil and trans fluid. And drive like there's a raw egg in my right shoe.

Jet chips have been around as long as popular car-based web forums. I've been on car-based forums for that long as well, and I've not seen a single instance where anyone used a jet chip with any success. Total garbage, they are.

An upgraded mass air flow sensor will do no good, either. Why? Your engine isn't actually changed, i.e. not taking in any more air. If you don't change the intake/output of fuel or air in the system, no changed component is going to make a difference, and it doesn't alter the tune within the engine management system.

The fact is with this motor, if you want a real, noticeable change, it's going to take money. Big money. But would you like a list?
AEM Infinity stand-alone engine management with wideband oxygen sensor setup: ~$1700
Full dyno and street tune: $500-1000
Horsepower gained? Good question. 10-30 maybe?
What you expect to gain in a good tune with a system like I pointed to above is refinement in power delivery and maximization of the capabilities of the system outside the bland, ultra-safe tune from factory. You'll likely see MPG increases with the power gain.

K&N filter? Not a bad filter, don't get me wrong.......but it's not going to affect your fuel economy unless the filter you have in there is clogging the intake system terribly.

You're better off making sure tire psi is sufficient, running ultra-low-resistance tires, keeping the car clean/waxed, keeping NO additional cargo/equipment in the vehicle daily, and making sure spark plugs are refreshed, oil is clean, and fuel is good.

I've chipped a few cars and only on my Subaru WRX was it really worth it. On my other cars it made a barely noticeable 3-5% difference that required running premium fuel. It's not worth it. I'm almost never smashing the pedal to floor in the Pilot so there is plenty of power on tap. I don't need more.

you absolutely cannot compare a legitimate tune via a Cobb Accessport or the like for a WRX to a generic 'jet' performance chip made for almost the entire lineup of cars available the world over. Jet chips and similar do absolutely nothing for anything.

And you can't compare a legitimate over-the-counter tune like those pre-programmed on an Accessport for a turbo car to a Honda pilot either.
