modified AEM short ram for WAI/HAI?

[Jakins]

Holly crap that was a big read haha. I was actually kind of hoping someone had already found what a perfect resistance is for civic hx IAT sensors but idk. I want to tune it like that but I don't have the electrical knowledge.

It's no big deal...you buy a pack of pots at radioshack for not much...you find a wiring diagram for your car...you connect where needed...run the wires inside thru the pot...adjust as you drive. You WILL need a Scangauge or other mpg meter to assist with adjustment. Will you see an mpg gain? Beats me. Other sensors can also be adjusted.

Can you do damage? Possible if you aren't careful? If you adjust for best mpg...probably not....

That seems optimistic. Did you ABA test it?

[suspectnumber961]

I don't do ABA tests. I did compare last summer's avg mpg with a similar period this year. I'm guessing most of the gain is due to the rounded intake area molded into the filter inside vs the straight tube intake of the OEM filter box.

I did notice that after installing the filter that I needed to rest the fuel used
in the SG for two consecutive tanks. Possibly the SG was sensing greater air flow from the MAF and indicating greater fuel use...fuel use that wasn't happening?

IMO...the whole ABA thing is nice when it happens but can be limiting and misleading as far as discovering what works for a particular vehicle.

WAY TOO MUCH "didn't work for me...or can't work at all" on this forum. So...what happens? Nobody tests anything because someone says it didn't or won't work...and somebody ALWAYS says that....especially if it involves increasing combustion efficiency.

I hunt easter eggs...if I think some mod might work...and I can manage the mod....and if I want to...I test it. It's that simple.

I don't need to prove to anyone that it does work....you need to do that yourself.

"I'm guessing" really is the operative term here. The gain could be due to so many different things with such a test like this, you really can't know. You made a specific claim about seeing a 5% gain from this specific mod, but it's really a guess. Your gain could be due to differences in average temps during the specific times and routes you were driving across the different weeks and several different traffic conditions combinations, on average over a long stretch of weeks. Confirmation bias rules such scenarios.

I don't see how a rigorously prepared and executed test, honestly reported and critiqued, misleads. It may limit, but that would be because it demonstrates something does not work. If you apply findings for one vehicle to your own recklessly, then you might unnecessarily limit yourself, but that's a matter of careful thought about whether a test applies to your configuration, such as a MAF, MAF/MAP, or just MAP set-up relative to this WAI mod.

I didn't say it didn't work. I asked you to show me that it did because I was curious. I agree testing can be discouraging, but so can encountering and believing a claim of a 5% gain when you're new to this site, only to discover $40 later that the mod doesn't work. If he has a MAF equipped car, there's no evidence a WAI will work.

One of the great things about this site is that the readers ask for proof when someone claims a specific and large gain, like 5%, from a debated mod, like a WAI and such.

My response = WHO CARES?

I will be testing a few things going forward but won't be posting anything on this forum about them...just tying up some loose ends.

Too much effort is involved in arguing with people who have it all figured out. I have the mechanical/scientific knowledge to argue some points...but it would be a waste of time....I have other things to do. I don't test for you...I test for myself.

My advice? Go find a cone filter and sit on it? Wear your engineer's boots when you do....

"My response = WHO CARES?"
I for one would love to read about all your tests and trials.
I try stuff that either is proven by others or is "tested" by me .. it works or it doesn't.
I am not the type that will try and prove to others that things work.
Please don't punish all the members and readers because a few want proof.
Back on topic I modified a used Fujita cold air intake into my hot air intake, it takes air from the exhaust manifold near the converter.

[Jakins]

i just did this right now. this is a nissan 240sx ram air intak. it puts the filter right in front of the radiator to hopefully pic up the hot air through it.

[BackroadBomber]

I love that Texas flag valve cover.

[suspectnumber961]

I want to make one final point on the cone filter mod. I THINK that the gain is due to increased air flow probably because the the molded in bellmouth shape inside the filter vs the straight pipe of the OEM airbox.

http://www.profblairandassociates.co...mouth_Sept.pdf

Conclusions focus on power gains...OF COURSE.

Evidence of this increased airflow might have been seen from the need to set the trip fuel used DOWN in my SG for the two refills after doing this mod. As I understand it...the SG calculates fuel used FROM the air flow measured at the AFM. Increased flow resulted in the SG calculating more fuel being used than actually occurred?

So if anyone wants to try this mod...you need to see inside the cone filter to be able to check for the bellmouth shape. I think these type cones can be found at Advance or Autozone for $25-30.

The results might be a figment of my imagination and/or they might be specific to the Focus. If your car does not have a bellmouth intake and the cone filter you install does...you MIGHT see an mpg gain.

Anyone fixated on ABA testing probably will not see the salient points.

NOTHING in life is certain...except for death and taxes????

The one exception though are ABA tests of course.

...

I don't expect to be doing a lot of modding in the future...just testing a few mostly easy to do things mostly involving improving combustion efficiency. Won't post them on this forum due to the arguments. I probably save $50 / month on fuel...so it's a hobby...not a job. More aero mods are not going to be happening...though I've done them in the past with my Batmobile 300ZX...vortex generators..air dam...fender skirts...all in black.
