Aquatune Review - How I turned my car into a hybrid +12 MPG

The follow up.

I wish I had more time on my hands to use a tank of gas but I've been tweaking & using Quarter tank runs.

The first setup I used the 4 hose direct injection style. This caused a rough idle & 80 Miles before the gauge started moving. With stock setup I had a decent idle & the needle started moving at 50-70 miles.

The 2nd Setup was thru the throttle body air intake vacuum hose. This resulted in me thinking my gas needle broke because I drove for 105 miles before I saw the gas needle budge. The idle smoothed out much better than stock because of an RPM boost.

Also 2 Half Gallon Jugs of water are gone.

Power, the car is stronger after I took it on the mountains here in Las Vegas, I no longer have to floor it to get up the hill. I took 0-60 Videos but they remained unchanged however.

I read the Pop mechanics & -20%-20% review before I bought the Aquatune but I thought their explainations was in detail like the Las Vegas news story.

That review very biased i think. If you look at the bottom of the page the guy has a link to his own 'hydrogen boost' website. Which sells a similiar product, I admit I would be interested in trying the hydrogen boost out but the site leaves out details on how his device is so much better than aquatune.

The dyno could be right tho but I dont have access to one. The reason is aquatune increases your base RPM. My old RPM base was 650-700 RPM, after aquatune its 1000 rpm. The 1000 RPM IS stronger than the 650 base when Im coasting..feels as if my braking power dropped a notch. However the New 1k RPM could be weaker than the pure gas RPM causing the 20% drop in power.

So far the aquatune met all my expectations. I installed it myself & had to go thru 2 test setups & 5 ecu resets before I got ir right. I do get an 0171 Check Engine light from time to time but after talking with Aqatune, it a problem with the Vibes emission system not being built to run hydrogen.

Overall mileage went way up, Power increased thru RPM increases a bit & I got a long ways to drive. Im planning to put this in my Grand Am GT also to see the effects. I also want to experiment with linking more than 1 aquatune results.

Got any links to more information about the Aquatune? That's a heck of a jump!

Welcome aboard WarMachineXX

I've been looking at the Aquatune for some time now. Big hold up has been the price. (Just missed an aquathrust on ebay for $250 today)
While i believe there is merit and a place for improvements via water injection I still don't see that they are getting the hydrogen that they claim.

Fran at hydrogen-boost.com had noimprovements for the unit. For most part his testing is more accurate than most you'll see online. Pop Sci got nothing. HOWEVER PopSci didn't get the right kit for their application. It's my understanding they ordered a kit and either changed their mind on the vehicle OR purposely changed. At any rate, they should have used it with a tbi spacer and they did not. They also mounted the unit quite far away which is contrary to instructions with the aquatune.

Fran's hydrogen units are electorlyzers that I understand to have a series of stainless tubes one within the next and run in a series.

I'd love to arrange for testing of an Aquatune. We're currently lining up testing of numerous other products that we'll be covering here and on fueleconomytips.com

Did you do any of the other changes they suggest ?
ie: fresh O2 sensor, coolant temp sensor.

Did you advance timing? or do anything else that would affect mileage with or without the aquatune.

Lol I was bidding on the aquatine on ebay today also, I bidded $150 at the last second thinking I was going to get a steal.

Anyway aquatune has a tech support which surprised me but they told me the basic rules for hooking it up was

Have the air input & Hydrogen Oxygen output horizontal41 (so water flows evenly
Put it closes as possible to the engine(closer path better suction
Have the water Jug at a lower level than the aquatune box so water isnt being siphoned

The O2 sensor is acting weird on me. Its detecting too much O2 & giving me random P0171 lean fuel errors.

For advancing the Ignition timing, I dunno how & didnt bother with it. The 4 way feed into the air intake gave me a worst ign timing than feeding the throttle body hose vacuum.

Thats kinda 'normal' with any mileage enhancements. We've also had vehicles lately that jumped dramatically when they put various systems on them and after the course of 3 tanks mileage returns to stock.

Seems to me you need to trick the O2 sensor into reading normal levels.

Isn't there a CatBox out there for that?
I thought SpeedTweaks had one but they went south I guess, and I'm not talking Mexico either!

NOPE, had one, didn't work. Computer kept resetting itself to 18 mpg hwy.
This was a replacement for the O2.

I fixed everything with a proper ECU reset. An fuel triimmer still would be nice tho

I recomend HeavyChevy for an O2 offset device. You're limited on how far you can push these things without tripping codes. Also be carefull as they lean out across board (while in closed loop). No saftey measures to keep from going too lean. Shouldn't be a problem with water injection though. Keep us posted on your long term gains.

Yes, Im taking it back lol.

It works ok & all but I experimenting with a hydrogenerator thats about 5 times bigger & only costs $140 in parts to build myself.

Main reason Im switching is to get 100% hydrogen oxygen generation injection instead of the split water h2 and o2 injection with the aquatune. After inspecting my plugs and O2 sensor for a week, they had rust on them. But oddly when I ran the aquatune without water... my mileage went up from stock..

As for the 100 miles w/o the gas needle moving I never saw that again. I think after the unit breaks in it loses efficiency or my ecu dumbed down because my O2 sensor saw too much O2(was getting Lean CELS). I never got the 450 miles a tank & +25% goal. Maybe 380-400, 360 was my record.

For the 30% HP boost is a little off. My 0-60s stayed exactly the same. The power came from advanced RPMS at idle & on hills.

The return policy is real turn off, they give you a 30 day return policy but imagine taking 30 days to drive & 31 days to fix it and not getting a refund, I just ran out of time. Also they charge you 15% restocking fee no matter what.

What I did learn was shell gas kicks ass. After looking back I used shell gas right when I put the aquatune in which gave me that 100 miles on full. Using anything else,even chevron, dropped my mileage. The real MPG hero was the shell gas.

No offense, but IMO measuring fuel consumption by 'it took xxx miles for the needle to move' is a very inaccurate way of testing. You really need to get actual mpg numbers when you fill the tank up. I'm not tryin to rip on you. Its just that I believe in testing as accurately as you possibly can, and I don't think that this way is accurate.

True, but I have kept track of the needle marks over time & use them to gauge efficiency per quarter tanks. Like I can have a great 100 miles before the needle moves off full but at the end of the tank it total falls off. This is exactly what happened Aquatune.

Its strange because I get the worst mileage after a ECU reset & then it gets better and better. With Aquatune it was the opposite, I was expecting 300 miles before a half a tank but only got 220. Its better than my 200 per half tank, but not the 25% guarantee.

Temporary Setup

Brown Foam After Effects. It all washed off cleanly car but not the jug.

Bigger Jug 1 Gallon Jug

Hose Nozzles For the Big Jug. I Made a Big-Small tube setup so that it creates a lower pressure in the jug hopefully getting more H breaking from bubbles.

Finally got everything in place to run hydrogen finally. I have to run a few control runs to get my MPG before & after.

On my first test I ran rubs into my airbox then it goes thru the filter. Figure its safer that way since im working with electrolytes that wouldnt be too pretty if sucked into the engine(vinegar). The mileage dropped big time. My theory is the fuel ratio is throw out of wack & im producing imploding gas not exploding.

I realigned my joe cell to do simple electrolysis, got the proper parts & will try again. Also I have a fuel trimmer this time(efie).

Before.
25-29 MPG. 87 Gas

Fuel Trim test
Fuel trimmed until the ignition at idle dropped from 19-16 Range to about 10-14. Added octane booster to about 93 Octane. Ignition went back up to 16-19 Idle range. This just shows that quality fuel means allows for a leaner trim. Therefor when I add the hydrogen I should be able to trim the fuel even more. Thats my first goal.

MPG test
Im using scan gauge AND proper calibration. Since my problems with the fuel heater I realized its #1 to calibrate the scan gauge, My current calibration calls for +8% adjustment. Meaning my scan gauge needs to add 8% to the fuel usage(8% is lost off mpg). I have no doubt that the fuel trim will drop the calibration in the negatives but I dont have those numbers yet. After adding hydrogen I hope to drop that calibration % even lower. I started at 30% got it down to 8%, my next goal is to hopefully get -10%.

In the end my mile range on a full tank of gas will be the judge but as much as Im working on all these things I dont drive much :).

Goal
40mpg
