Thanks buddy, here is the new thread that I created...
http://ecomodder.com/forum/showthrea...tml#post369779

One big thing though...you guys keep talking about the A-B-A test (and others) too...but I'm not sure what that means. Can somebody please explain?

If I can do some more testing to validate one way or another then I'll be glad to but with that said, if it takes more money (like buying a nonmoddified TBI and "equipment") to use for testing...I don't have the money to do that but I can tell my opinions and experiences and show them as they unfold. I can also show base line MPG and after etc...

If anybody has any suggestions please let me know!

Thanks,

Wayne, SC

When someone puts a Kammi back, or under body smoothing they may not have done any testing but there is real research (not just testimonials) as to why one could expect such a mod to work. On top of that they are not trying to sell the thing.

When selling something it is right to be held to a higher standard. When asked if he was able to provide evidence (not hearsay) he (Ron) balked.

Alright, I completely understand this! That's one of the reasons that I started the thread today that I did.

That said, what/how will I be able to show evidence...I'm open to this as much as you are, I'm just another guy in the world trying to "make it" and save some money...

How can any of us (in this case me) show tangible evidence that can be used as factual knowledge? I'm not doing this to defame my YouTube channel or my person...I just want the truth...in whatever form it takes.

I'm open to meeting up with anybody that is near me in the Carolinas!

Wayne,
Read the posts in this thread on testing.

But let me add my 2 cents.
1. need a calibrated scangauge/similar device
2. need a section of freeway (10-15 miles) that you can run on at cruise speeds - up and down.
3. I would then run(controlled with cruise control) at 50, 55, 60, 65 & 70 and record the results from the scangauge.
do runs w/ a/c on (A)and off (B)
Do runs with psi at 30 (A) and 40 (B).
record the out side temps, time and wind etc.
those are now your A and B base line tests.
B

That's where I disagree.

If someone wants to slap something they made on their own car and doesn't care about properly testing it, that's ultimately their own problem.

But when someone is actively trying to sell that mod... trying to get people to part with several hundred dollars for something without properly documenting its effectiveness, that's a whole other ball game.

It's reasonable that those people and their mods should be held to a higher level of accountability than hobbyists.

I see what you are saying, I agree with you here actually. I want to do this testing properly and make sure we can know if it works or not. I may have to wait a couple of months for the funds and then go back and do it (the testing) but either way, it's gong to get done.

Here you go:

http://ecomodder.com/forum/showthrea...ery-11445.html


The simple version is:
- Try to set up conditions in as repeatable and consistent way as you can.
- Take one set of data without the modification.
- Take one set of data with the modification.
- Take a second set of data without the modification.

In this case "A" would be with no mod, and "B" would be with the mod. ABA helps to try to isolate any changes to the thing you are trying to test, rather than random variation. If the two "A" tests give results that are close to each other and the "B" result shows a clear improvement over both, then you have good evidence that the mod was effective. If not, then you don't.

Since driving style and external conditions (engine temps, air temperature, rainfall, weather, tire pressures, uphill or downhill, etc.) all have an impact on MPGs, you need to set things up with all of those controlled to as close to the same as you can get. For most of us, that means picking a calm day or time of day, doing several runs each direction in quick succession on a given stretch of road, using cruise control, and so on. It's kind of time consuming, quite frankly, but if you want good data you have to put the time in.
