Below is a synopses of what I've done with a Honda Civic.
My car without anything done to it was getting 30-32 mpg a HHO unit and EFIE
took that to 40 mpg I took the HHO unit off for this test of the Hull Effect
Go here if you would like to take a look

I travel 50mi to work on the freeway - speed locked at 70. I have about 5mi on
both ends that are some stop & go but generaly
travel about 35 with sincronized lights - so I'd say 90% highway 10% stop & go
Tack average just under 3k

> hi froze
> how many miles have you done on the civic since the switch and when did the
switch start to take affect?

Immediate I think but very mellow or subtle. I didn't notice anything till I
thought it wasn't running in the parking lot.
Still consider the power thing odd - yaknow hard to say BUT Here's my
actual data so far.
Date Odometer= Milage Gallons MPG
4-30-09 - 227129 - 548 - 7.755 ----Full Tank
5-05-09 - 227418 - 289 - 7.65 - 37

5-14-09 - 228112 - 289 - 7.65 - 37
5-19-09 - 228604 - 488.5 -5.35 - Partial fill
5-21-09 - 228680 + 76 + 7.847 - 42.7 - Removed HHO unit
5-22-09 - 228681 - and introduce signal w/Switch
5-25-09 - 228952 - 76 - 1.76 - 43.18
5-26-09 - 229028 - 348.4 - 7.703 - 45.25

6-13-09 - 230276 - 302.1 - 8.01 - 37.71
Latest fill figured at 43.5 mpg But I don't have the receipt in front of me. I
don't beleave the Effect has fully occured and is still building. Time will
tell. But for about $75 and 4 hr work - Big Smile
This is on a Fuel Infected car (Witch dose not work well - We need to figure out
(Why!)
Need help :') Prob because of the magnetic pulse from the fuel injectors.
The one who found this effect says Car-berated engine Is best and dose Much
Better.
I am working on one now. Should be done in couple weeks. I'm hoping for 1/4 the
fuel usage w/twice the power.
These figures are from the actual receipts (Not just done in my head then
reported by memory)
Don't know what's up w/6-11-09 - Hadn't notices till siting down to do this.
6-16-09
Earlier today I pulled out onto the highway in a tight spot and after looking at
the rearview mirror,
thought I'd speed up so I wouldn't hamper the truck behind me. 2nd gear and she
wound up to about 4k and
woosh 6-7k shift 3rd and man I'm doin 55mph shift to 5th and brake slightly so
as to not gain on the car in frount,
try to act like Nothings Happening. HaHa Cruse to town. Very interesting.

June5-09 Re: Effort
OK two tanks of gas 2nd read was 27MPG - Found leak in fitting when Engine
running. Soon as shut off
(As checked previous) would evaporate off rather quick. so fixed that. 3rd read
(w/say 1/4 run with leak) was 34MPG.
I think their is a slight and I mean slight bit of power increase but this
might be subjective. NO other Positive attributes
noticed. BUT it dose smell like its running very rich. Sometimes when its
running hot after long drive it is very hard to start.
Like its flooded. Have to sit and wait 5-10min. or it loads up agine and will
run down the battery.
I have no idea how I might reduce the fuel delivered. Will wait till I get the
Van done to mess with it any more.
Then want to try a vapor can and HHO to see if i can get it to run with the
injectors shut off (Disconnected).

I wonder if my 300 to 400 guess is as accurate as I want. might be to low maybe
5-600 but definitely lower.
Need to get one of those Diagnostic Tachometers. Will start looking.
I filled up on the way home this morning in the early hours. 345 miles 7.64
gallons = 44.67 mpg I think.
But need to check Total miles to make sure I Zeroed Odomiter last time I filled.
Have to go through all the reciepts - 2 hour job. Got to sleep more gfirst.
Normal milage w/out HHO or EFIE is 30-32 mpg with HHO & EFIE 40-43 mpg.
This run is w/out HHO but EFIE for oxy sensor on. (EFIE fools Computer that full
burn is occurring so it wont dump more
fuel in to burn up the excess Oxy (if their is any) I will add the HHO with Dry
Cell soon - After conferming MPG.
Just for info pourpose. I intend to fully convert this rig later.
But this is with the fuel injection as is. OH had to take my fuel regulator out
of fuel line to get it to run day befor yesterday.
Teed it off and will add "Y" valve for later conversion to carb type input. Need
to put injector switch in so I can shut it off.
Important to be able to convert it back for inspections.
Till later FrznWtr

HI KP
Still have the injectors working. This is said to hamper the effect reaching
full effect. IT'S NOT A FULL CONVERSION.
Just want to make that clear. I put a remote Oil filter kit on and put the
signal in the returne hose. Thats it so far.
The idle went down and I'm still cking milage but I think it is better.
I had a EFIE on the Oxygen sensor already from HHO experiments.
I also have a "T" in the fuel line I'm tempted to put the signal to but, want to
CK MPG this way first.

OK install on Civic done. Yippie
Took it for 20mile run. Dident notice anything till I came out of post office.
Normal Idle has always been around
1000rpm maybe 900. It was down to 600 and just purring along. Brought it home
and set Idle down to between
300 and 400cant tell as tack is original and not segmented at that point. 0100
tomorrow to work.
