Added WAI to 06 Kia Sportage A-B tested

[mcrews]

here is the link to the current work on the 2006 Kia Sportage V6 EX FWD:
http://ecomodder.com/forum/showthrea...ins-24006.html

Today 5-17-2013 test from 3pm to 3:45pm

Added a fujita Cone filter right at the Mass Air Sensor
Removed Air box that was being fed air from the upper grill

Thus a WARM Air Intake.

Outside temp: 90 degrees
wind: hardly
no humidity
Ran east & west on 1604 with cruise control set at 52mph (sorry meant to set 50mph) 5 miles each way
ScangaugeII is calibrated to Garmin GPS.
Air Conditioning ON.

Results:
3pm at 52mph
a1: 25.3mpg 213Wft 161Fia
a2: 25.9mpg 213Wft 161Fia
a3: 24.6 225 161
a4: 25.2 225 166

Installed Fujita Cone at MAS.

B1 27.1mpg 225wft 177fia
B2 28.4mpg 222wft 177fia
B3 25.5 mpg 229wft 170fia
b4 28.8mpg 225wft 175fia
THoughts:
surprised the fia was at 160 range w/ factoryintake air box housing sealed
also not really happy w/ engine temp in the 225 range on a 90 degree pleasant day.
May install an aux fan that I pulled off the infiniti Q45 before I sold it.
(kinda like my lower complete grill block and dont REALLY want to open it.)

looks lkie the WAI might be worth 2+ mpg

hell yah brother. its been working for me too. well the hot air intake has been

Unfortunately, on my own vehicle, hai showed 5-6% improvement w/ scangauge, but was almost undetectable when I filled up

[mcrews]

then something is not calibrated......

My Kia is off brcause of the taller tires, but when I factor in the difference I am with in .5 mpg of the scangauge which is calibrated to the GPS.

Right, the problem was I bumped the sg's adjustment up a little bit tank by tank at fillup until most of the gains were gone. Eventually I removed my hai because once it was built to provide decent heat driving on the interstate, then it cause drivability issues in traffic. After removing the hai then I needed to adjust the sg back down at fillups.

Just saying, for me, on my car, the hai fooled the sg far beyond my actual gains

It didn't make sense to me either, but does it make more sense that warm air increased his engines efficiency by almost 10%?

Well there is quite a margin for error in the testing methods used of course. 2mpg is a very rough guess based on an A-B rather than A-B-A. What I gather from mcrews' info is that it seems to be making a noticeable difference in his fuel economy based on instrumentation.

What you seem to be saying is that you felt it was throwing your scan gauge off somehow? Did you come up with a theory as to why it might have skewed the numbers?

[Sean.Heihn]

Doesn't the MAS measure airflow by cooling rate of a heated wire suspended in the airflow? A WAI might decrease the cooling rate of the wire for the same airflow rate, so an ECU calibrated for a stock intake may think that means a decrease in airflow. And since a SG uses airflow to estimate FE, it might cause an increase in instrument MPG, while the exhaust O2 sensor keeps the FAR near stoich meaning real MPG never changes.

Edit: Hot wire MAS can still accurately measure air mass, not volume, despite changes in temp.

Makes perfect sense. A scangauge is not the correct tool for A-B testing engine mods. No doubt the HAI has thrown the SG's calibration off. A few calibration fill ups will likely prove this. SGs are only good for A-B testing aero mods, changes in driving habits, etc.
