A note from Chris Richards, president of Mass-Flo
EFI.
With today's economy, and with gas prices what
they are, I felt it was important to address the
issue of fuel economy, and what you can expect for
increases from our Mass-Flo fuel injection system.
Quite simply, no other aftermarket fuel injection
system even comes close to what we can do for your
vehicle. With today's fuel prices, the increases
if fuel economy you will likely see, could literally
pay for your investment in a Mass-Flo system in
a very short time. While it is impossible to say
exactly how much of an increase you will see (there
are simply too many unknown factors), you can expect
the results to be dramatic. We receive testimonials
such as the one below almost daily.
Been running the T-Bucket
with a 400 SBC for over 27 years and have logged
over 250,000 miles. Converted to your EFI setup
and can say it has never run better. Last June I
rigorously measured my fuel mileage from Dallas
to Sierra Vista, AZ and back to Dallas. Only 13.8
mpg on the highway. Put 92.9 miles on the bucket
yesterday (city miles and I drove it hard, went
to lunch, at least 30 stoplights). Got 19.9 mpg
in the city! I'm going to drive to Springfield,
Ill in a few weeks and hoping for 22mpg, almost
as good as my Ford Fusion.
Update...
Wanted to follow up with
you on my trip to Springfield, Ill. Used a GPS to
measure the mileage and kept track of the fuel usage
-- 22.1 mpg on the highway plus I was pulling a
small trailer. Significant improvement over the
13.8 mpg with the carb. Great EFI setup!
Installing a Mass-Flo system helps clean up
the environment, and helps to reduce our dependency
on foreign oil. It will also dramatically improve
drivability, cold starting, and power. If you're
still using that sloppy old carburetor, or if you
have already purchased a competitor's EFI system
and are less than satisfied with the results, I
invite you to see what a Mass-Flo EFI system can
do for you. You'll be glad you did!

Make
no mistake... This is the best fuel injection system
available. All the benefits of a MASS AIR
fuel injection system with the vintage look of a
4bbl carburetor. It is NOT A SPEED DENSITY SYSTEM
like other similar systems. It uses production (not
aftermarket) mass air engine management, for years
of trouble-free service and production car quality
driveability, while providing real performance benefits
over a carburetor or a speed density system.
Why our system? Here's why!
Don't settle
for empty promises, GET REAL RESULTS! The
other companies make it sound as if it's a benefit
to have the ability to "tune" their systems. It's
NOT a benefit... IT'S A HASSLE! The
reality is, programmable
speed density EFI systems are not much more efficient
than a 4 bbl carburetor. You're punching keys on
a computer, rather than turning screws and changing
jets and springs in a carburetor. The end result
is an expensive system, that cost almost as much
money to get tuned properly as the initial cost
of the system. And where is the advantage? They
require constant laptop fiddling to keep running
properly. You could have gotten that with a carburetor!
They
are a little more efficient than a carburetor, but
not enough to justify the cost. The only thing worse
than a programmable speed density system, (besides
a carburetor), is a NON-programmable speed density
system. Non-programmable speed density systems only
work on bone stock or specific applications. Non-programmable
(or non user-programmable) systems are factory calibrated
to a specific engine, with a specific combination
of parts. They have no provision to account for
variances such as engine modifications (even minor
ones!), vehicle specifics, or atmospheric conditions.
The result is, they just do not work very well.
The
latest thing being offered by the competition is
the "self tuning" speed density EFI system.
They claim that their system will tune itself while
driving. This is very misleading. These systems
DO need to be
programmed by the installer, so don't be fooled
by their careful use of words. They are far from
"self tuning". These systems require you
to tell the computer what air/fuel ratio you want
under any certain set of circumstances. Keep in
mind that the real benefit of a good EFI system
is all the knowledge that you buy with it. Our computer
comes with all the programing done for you. With
our system, you get the benefit of thousands of
man hours spent by the OEM fine tuning the processor.
It is simply not practical for you, or a dyno shop,
to even attempt to duplicate the expertise you get
pre-programmed into our processor. Even if you spent
months attempting to perfect your tune with one
of the "self tuning" systems, it still
would not nearly compare to what we give you with
our system. Quite honestly, if you're thinking about
buying one of the other EFI systems, just save your
money and buy a carburetor. Their "self tuning"
systems do not offer enough benefit to justify the
cost.
In
addition, many of the competitors EFI systems are
"throttle body" systems. While these may
offer some ease of installation, the benefits over
a carburetor are minimal. Throttle body systems
are not nearly as efficient as our Sequential Port
Fuel Injection system. For more information on throttle
body vs. port CFI, please see our Q&A page.
Our MASS
AIR system does it all for you, and provides
REAL PERFORMANCE BENEFITS over a carburetor
or speed density system. It is by far the most user-friendly
and most effective aftermarket fuel injection system
on the market. Get improved power and torque as
well as improved fuel economy, performance and reliability.
Unlike programmable speed density systems, you will
never need to tune this system. No laptop, no hand-held
programmer, no tuning or tweeking, no dyno! This
saves you the hassle and expense of tuning and trips
to the dyno. When it comes time to make further
engine mods, chances are you will not need to change
a thing on our system. If you plan to make LARGE
gains in horsepower, and you need to change
your injector size, just return the computer, and
we will recalibrate it for you, rather than retuning,
reprogramming, and more trips to the dyno. Our system
is even easier to use than a carburetor. You need
to tune a carburetor. With our system, you just
install it, and you're done!
So how does it work?
Any
naturally aspirated engine, regardless of brand,
size, combination of parts, etc., requires a given
air/fuel ratio, at a given load. These ratios do
not change from engine to engine, until you get
into forced induction applications. (We'll get to
that later). The needed air/fuel ratio changes with
such things as engine temperature, air temperature,
and atmospheric pressure, but the needed changes,
again, are the same for all engines. The task for
any management system is to add the correct amount
of fuel to the amount of air that the engine uses.
Carburetors do it mechanically, and so, are mechanically
limited as to how accurate they can be. Speed density
systems do it by comparing the readings from various
sensors to tables within the engine controller to
try to determine the amount of air the engine is
using. This actually works very well, IF THE VALUES
IN THE TABLES ARE CORRECT, and there lies the challenge.
There are a lot of values, and a lot of tables,
and a professional tuner is required to enter the
correct values into all of those cells in all of
those tables. But you are not done there! The next
step is to drive the vehicle in the real world,
and adjust all of those values to tune out all of
the drivability issues you will have. The other
problem is speed density's limited ability to self
adjust, and so, your laptop must permanently reside
in the passenger's seat. Worse than that, non-programmable,
or pre-programmed speed density systems arrive at
your door with the programming done. They have been
pre-tuned at the manufacturer on the dyno with a
pre-determined combination of parts on a specific
engine. That would be great, but remember the part
where this does not really work very well in the
real world? Well, with these systems, you can't
even fix it! Even worse, if you want to make a change
to your engine, you simply can't.
Mass-Flo does it differently. There is a Mass Air Flow Meter Hidden away inside your air cleaner. This meter can actually measure the amount of air that is entering your engine, and again, if you know how much air the engine is using, then you just add the correct amount of fuel. It's that simple. The air/fuel ratio is adjusted accordingly to compensate for the load, and variances in engine temperature, air temperature, and atmospheric pressure by reading values from sensors that are included in the system. If you decide to make improvements to your engine, Mass-Flo simply adapts to those changes. Keep in mind... An engine is just a big air pump. Changing heads, camshafts, intakes, exhaust systems, displacement, etc., are just ways of making your air pump more efficient, or in other words, using more air. Since Mass-Flo measures the amount of air the engine is using, it simply adds the correct amount of fuel. With speed density, it's back to the dyno to start all over again.
In
forced induction applications, the ratios are different,
and a different tune is needed. We also have a tune
to cover those applications. In fact, Mass-Flo can
be adapted just about anywhere. If you want something
made custom, let us know. We can do dual quads,
and other applications where two Mass Air Meters
are required. In all cases, no tuning is ever required
by the customer.
There's
one other thing we should mention... Speed density
relies heavily on the signal from the MAP (manifold
air pressure) sensor to determine how much fuel
to add. This sensor measures the engine's vacuum
at the manifold. So what happens when your camshaft
produces poor vacuum? You guessed it... Horrible
drivability is the result. Mass-Flo does not use
a MAP sensor. You can use any camshaft you want
with our system.
Not all Mass
Air systems are created equal.
We
frequently get calls from people who say that they
already have mass air management in their production
vehicle, and when they made changes to their engine,
they needed to get a chip burned to make it run
correctly. Many will say that even the chip did
not make it right. They are correct...
The
fact is, there is only one management system on
the planet that will allow us to do what we do...
OURS!
Most
production management systems will work wonders
with a stock engine, or something with minor modifications,
but are not so great with an engine that is too
far from stock. General Motors systems, for instance,
do not respond well to major upgrades, and no amount
of chip tuning or dyno time will make it right.
They run, but not quite as well as they should.
Ours works differently. It's all in the programming!
Additional
features.
Cooling
fan control.
Simple one wire hookup for cooling fans. Just connect
the provided power supply to your cooling fan, and
the computer cycles the fan on and off based on
coolant temperature.
Idle compensation
for air conditioning.
The computer will automatically adjust the idle
speed to compensate for the drag created by your
air conditioning compressor.
Air conditioning
compressor cutoff.
The computer will automatically cut power to the
air conditioning compressor at full throttle, saving
horsepower for maximum performance during acceleration.
Things you should know before you buy...
No matter how good any system is, eventually, you may need parts or service. It may be 20 years from now, but at some point, it may happen. Truthfully this system is quite simple, and there is little that could go wrong, but should something happen, someone will need to diagnose the system, and get replacement parts.
Let's
look at the first part... Diagnosis. First of all,
when you go to the garage for repair work on any
of the other systems out there, you'll likely have
trouble getting them to work on your engine, because
the system is unfamiliar to them. If they will work
on it, they will not have diagnostic information
readily available to them, and they will need to
spend wasted hours on the phone with the manufacturer
getting tech support. All the while your repair
bill is growing ever larger. With our system, everything
is familiar. Since our system uses production engine
management, it is serviceable at ANY automotive
service center. Unlike the other systems on the
market, our system is comprised entirely of proven
and familiar components that have been used for
years in regular production vehicles. Almost every
repair shop has a diagnostic scan tool to get diagnostic
information and trouble codes from production engine
management systems, and the literature necessary
to make the correct diagnosis (code definitions,
and diagnostic charts), so diagnostics on our system
is easy. In fact, most problems you could easily
fix yourself. All that's required to get trouble
codes with our system is a jumper wire, and the
code definitions are right in your manual.
Now
the second part... Getting parts. Since our system
is comprised entirely of components used on regular
production vehicles, everything you will ever need
is on the shelf at the local parts store, AND
ALWAYS WILL BE! Try that with the other systems!
With their systems, you'll need to buy parts directly
from them, and wait for them to arrive. In the mean
time, you're going nowhere. That's assuming that
parts are still available. Most companies change
products every couple of years, and discontinue
the old stuff. How about if the processor (computer)
goes bad? There goes all that time you spent programming!
With our system, you just go to ANY parts store,
pick up a new processor, and plug it in. It's already
all programmed and ready to go, right off the shelf!
The other thing worth mentioning, is the fact that
we could go out of business tomorrow, and it would
not mean a thing to you as the customer. We have
no intentions of going anywhere, but it happens,
and if it did, everything you will ever need will
still be at the parts store.
You
should also consider reliability, and longevity.
Aftermarket electronics just can't compare to production
car components in either category. And when they
fail, you need to go back to the original manufacturer.
That's assuming that they are still in business,
and/or still make the parts. Since our management
systems are made up of entirely production car components,
failures are extremely rare, and parts are always
available.
