ECO Systems VPE Test Results

Think of it this way (example by figurative numbers):

Let's say the cost of an customized ECO-2 for a 4.0L V6 is $100 (parts, assembly, labor, and logistics) to the automobile manufacturer, and they put it on JUST the Tacomas. That month they sell 24,000 Tacomas. They just increased their production cost for that month by $2,400,000!

If they don't get a real benefit out of that cost (as it only benefits the consumer), then why would they do it. They don't want to raise the cost of the vehicle for something that won't benefit a consumer that only drives 10,000 miles a year. They want to put in features that benefit everyone (or so they think).

Does that makes sense, or am I talking in circles?

 

Thanks! I figured if I was going to do this for the forum (and not just myself), then I better put some real work into it.

I will tell you this much about driving the vehicle with it in - you notice it. My "butt-dyno" could tell when it was hooked up and not.

 

Does your butt dyno think the performance is better with it hooked up?

 

I can't speak for the 4.0L (maybe some one else can), but on the 2.7L:

Definite torque improvements under load. It climbs hills better, and it hauls a load down the highway better. It also reduced response time on the low end. These aren't huge improvements, but they are noticeable.

 

I will concur with 007's butt-dyno assesment. There is a noticably improved throttle response with the VPE installed on the 4.0L. It will hold the same hill in 6th gear now that required 5th without it. The improvement that was easiest to notice was under load, ie: with my trailer in tow, the truck just seemed to accelerate from a stop with significantly less effort.

I'd call it probably a 3-5 HP increase and 5-10 ft/lbs. But that is just from my butt-dyno, and unless someone else runs their 4.0 on an actuall dyno those are the only numbers we'll ever have as the local dyno shop around here has a reputation for blowing $h!t up so I won't be trusting them mith my truck.

 

They have not banned me. I doubt you have worries.
Ten yrs. ago we had some real flame wars.

Hi guys, first time poster here. I've been skimming through this thread with interest and wonder if the group buy has lapse? My 08 Taco is due to arrive soon after Xmas and I'll pick it up before New Year. Looking forward to learning more about available mods.

Remi

 

The group buy was slated to end on 12-20, but PM ecotaz (manufacturer's rep) and ask if you can still get in on it. Can't hurt to ask right?

 

how much are they without the GB? And where do you get them? I tried finding it on their site, but had to go to a dealer. There isn't on in NY, and I didn't want to call until I was ready to get one.

 

I feel like a tard, but what is the ECO1/2 VPE? I cant seem to find any info on it not to mention pics.

 

ECO-1 and ECO-2 are Vapor Pressure Enhancers.

The ECO-1 is for 4 cyl. engines, and the Eco-2 is for 6cyl engines and 8 cyl engines up to 5.0L displacement.

They connect in-line between your fuel pump and the fuel rail of the vehicle and promote a change in the the fuel entering in the combustion champer so as to create a more complete burn thereby increasing power (slightly), increasing fuel efficiency (noticably), and decreasing overall emissions (un-confirmed as yet in our personal tests)

The reason that you can't find the specs on them or photos is because this thread is just the results of the tests that 007tacoma and I conducted on these devices, in advance of the group buy that just ended.

Photos of the devices, their install, and innitial information regarding them can be found in this thread http://www.tacomaworld.com/forum/2nd-gen-tacomas/2714-better-gas-mileage.html

Be advised it got to be a very long thread, and tended to get off-topic at times, so it will take you a bit of time to get through it all. That is why the results thread was made seperate.

Regards,

 

I don`t think that I need to know all this.
I have a hard enough time keeping up with what the Inf. is doing.
I think I will just turn it over to my dealer and say."Do the best that you can.".

 

Quick question and hopefully someome can help me! I have a 2000 Prerunner w/ a 3.4L it does not have quick disconnects for the fuel lines... Can anyone tell me how they installed the ECO 2 on their truck without cutting the fuel lines....

 

here is my current numbers with the vpe and vpe unistalled. So far it is not looking good. =( I am getting more range without the VPE installed. I am starting to wonder if this device only works for older cars as my truck only has 7789 mile on it.

Test Truck:
AFE intake CAI installed
5 speed auto
V6
4X4

Good morning,
I noticed you are running the test backwards by first installing the VPE and then taking it off. As your truck begins to carbon up again it will start to lose mileage again. I also notice that with the vpe you have several tanks with 89 grade and after removing the ECO it is all 91 grade. This affects your mileage as well. Are you fueling from the same station as well?
As our first 2 testers did on the initial testing they kept the test on an apples to apples test.
On our website you can see that NASA at Whitesands test facility tested several units since they are mandated to get a 5% fuel savings on their fleet. Their findings were well over 10% on the vehicles tested. We now have many more New Car Dealerships selling our product due to their findings on fuel savings on their new vehicles.
Thanks,
Ben

 

Hello Ben

I am doing more of a real world test. I use a few different gas stations but there are 3 I use the most.

You can tell me all the lab and nasa results you want but that is not real world scenarios. Those are perfect world scenarios.

I am not saying your product does not work and I am not done testing. However my truck is still rather new and I do not have much millage on it. I installed the VPE when the truck had 2000 miles on it ruffly. So it had carbon build up.

I will be running more tanks without the VPE then put it back on and see what happens. I will report my results once I have them.

 

Just an FYI, The engineers at NASA that tested several of the units did do a real world test and not a lab test. The vehicles were run in their everyday fleet operations.
Thanks,
Ben

 

I would like to say that the guys at Eco-Systems are great! I had a little issue with mine and fired off an email, on Saturday and I was not expecting to hear back until today (at the earliest, more likely another day or two). Well, I had a response waiting for me only a little while later and by Sunday afternoon, the problem was taken care of. Do those guys ever take any time off? LOL Actually, I was very impressed with the way they were concerned about my situation and their willingness to help.

 

I've had my ECO-2 on for a couple months now and there is a clear increase in mileage. Tracking everything very meticulously, I saw about 1mpg increase by puting the VPE on. That was about a 6% increase over stock. I then swapped out the dino juice for synthetic and got another 1 to 1.2 mpg average (~7%). I'll be getting rid on the dino juice in the diffs and tranny in another 5 or 10K and I'll bet there's another increase.
