I have experienced
an anomaly lately with my mpg reading on my Scangauge, but I think I have
it solved. I have had my Scangauge calibrated to my system when
using the electronic control circuit. The engine displacement is
set at 1.7 liters even though the engine is 1.9 liters displacement.
After about five tanks full of setting the Scangauge refill variance at
fill up, the tank trip mpgs were always right on with the
calculated mpg at fill up.
Lately I wanted to do some experiments with the electronic circuit shut
off for purposes of sales in states and nations that won't allow the
circuit. Plus I had a loose connection because I never soldered
the wires to the circuit, and this was causing some hesitation.
Well, my Scangauge mileage has been bad and I've been blaming the cold
weather, winter tires, and the winter fuel, which all changed at pretty
much the same time.
days ago after testing mostly normal driving habits with no driving tips
involved, I refilled and compared the mpgs again and they were way
off. My calculated mpg was something like 42.8 but the Scangauge
tank trip mpg was only 37.7. This means I was getting over 13% better
mileage than I though I was getting by watching the Scangauge. No
wonder I was still getting just over stock mpg while driving normally.
If I add the missing 13% to the Scangauge mpg I am still getting a good
20% increase over stock equipment, even though I had cold weather,
winter tires, and winter fuel.
of you that have a Scangauge and use the electronic control circuit,
don’t be alarmed if you have a loss of Scangauge mileage when you
decrease your electronic control circuit setting. I find it best to simply set the
control circuit and forget about it.
All the “fine tuning” and tweaking I’ve done has not really achieved
anything. Find a good setting
and forget about it.
those of you that don’t use the electronic control circuit or can’t use
it because your car has the wrong type of MAF sensor, don’t think you
are losing 13% of the mileage you could be getting. You are not. My 13% difference between the
Scangauge mpg and the calculated mpg was coincident with maybe a 15%
loss of indicated Scangauge mpg.
So really I only lost a couple percentage points in real
mileage. Remember the
calculated mileage was higher than the indicated Scangauge mileage.
are talking about the Scangauge I’d like to address some complaints
that have been received at the Scangauge factory. I guess many drivers using the
Scangauge expect it to indicate accurate mpg as soon as they attach it
to their vehicle. The Scangauge
is a mileage calculator that gets information from a variety of sensors
on a variety of vehicles. No
two vehicles are alike and certainly sensors on different types of
vehicles will not be alike either.
A calculator can only be as reliable as the information it
receives from the vehicle it is attached to. The Scangauge is a great calculator that requires
calibration to your vehicle before it can be accurate on your
vehicle. Please don’t expect it
to know that your MAP sensor reads a little high or that your RPM
reading is a little low, or that your intake air temperature sensor got
clogged with dirt. Go through
the process of calibrating your Scangauge and you’ll have a very
accurate mileage readout at all times.
been hesitant to give out all the news about what is going on with our
company. In the last few months
I have discovered another handful of companies on the market that are
producing and selling Hydrogen generators/electrolyzers for motor
vehicles and making claims from 8% to 40% increases in mileage. I welcome these new companies to the
market as they are bringing business to us, because the more people are
informed, the more they will search the internet for alternatives. There is plenty of business out
there for all of us and the public needs all of us to get the word out
to them about the benefits of on-board electrolyzers.
concern about these companies is that they are making claims that are
not realistic with hydrogen injection alone. I have never seen an increase in mileage of greater than
10% caused by the addition of a hydrogen generator/electrolyzer, even
one of ours that produces three times as much gas as most of the others
out there. I have seen a loss
of 10% in mileage when our hydrogen generator burns a fuse or runs out
of water, but that is only when we have adequate fuel vaporization to
take advantage of the electrolyzer (hydrogen) gases.

to understand how the hydrogen generator works best when combined with
heated fuel and a good vaporizing system.
To get a
20-25% increase in mileage without driving tips, it takes more than
just a hydrogen generator/electrolyzer. Our comprehensive system that addresses all areas of efficiency,
from combustion properties, to lubrication, engine treatment, tire
rolling and wind resistance, and method of maintaining kinetic energy
through driving techniques, will indeed meet and surpass the claims of
up to 40% increase in mileage. In fact it is our experience that a consistent 50%
increase in highway mileage and up to 100% increase in city mileage is
very achievable. We have done
it with most every vehicle we have personally worked on.
