Everyone knows that when you modify an engine for
more airflow, you need to supply it with more
fuel. It only makes sense that you need to add
more fuel when modifying the airflow of your fuel
injected vehicle. With a carburetor, you simply
change jets. With an electronically fuel injected
vehicle, you must change the computer settings to
deliver more fuel. If you cannot set up the
computer to deliver the correct amount of fuel,
how can you ever think about going faster?
Supercharged cars can do away with
the factory-supplied fuel management units (FMUs)
entirely when the correct size fuel injectors are
used for the horsepower level anticipated. We can
program the computer to use almost any size
injector, right up to 160 lb/hr for you alcohol
racers. There is no need to trick the computer
into using bigger injectors by messing around with
recalibrated mass air meters, special "injector
drivers", or other gimmicks that are typically
sold in the aftermarket. An example of "stone age
technology" is the FMU itself. NO PRODUCTION HIGH
PERFORMANCE CAR HAS EVER BEEN FACTORY SUPPLIED
WITH AN FMU! Serious race cars with access to the
engine control system eliminate the FMU
altogether. There must be something to this. Look
at these vehicles and see if you can find an FMU
or a boost timing retard device.
Buick Grand National (at one time,
the fastest production 1/4 car ever made)
1984-1986 SVO Turbo Mustangs
1989-1993 Thunderbird Super Coupes
(supercharged)
Porsche 911 Turbo (fastest mass
production turbocharged vehicle in production)
any Indy 500 or Formula 1 race car
Swanson Performance custom EEC
computer modules can accurately deliver the fuel
that you need for high horsepower efforts, thereby
eliminating the need for obsolete "half-fixes".
