Thank you for your interest in the all-new RetroTek BossEFI system. The
story in Hot Rod magazine came out a little early and our site was not ready
to go up so we will be adding info daily.

PRICING
To answer some basic questions, the system is set to target the $2000.00
price range for the 930cfm body and comes as a complete package. The
Throttle body bolts in place of a Holley or similar 4 barrel and has the
same overall dimensions, so the air cleaner will remain in the same
location.

SELF-TUNING COMPUTER
The computer is the first self-tuning system available and is a speed
density ,closed loop system . We use a PLX wide band (included) and the
system delivers hands free tuning at all loads and RPM²s. The key to our
system is its VE SYNC which reads the air fuel of your engine and re-writes
the base fuel table to deliver the exact Target Air Fuel ratio desired for
your engine. This can be done while viewing the info on a laptop, or without
one. The system re-programs itself so the oxygen sensor does not have to
work to correct an inaccurate calibration each time you run your engine.
Once this is done you can leaved the O2 in place to compensate for various
fuel and elevation differences. A video demonstrating a system being tuned
will be posted on the site shortly so keep checking it out.

ADDITIONAL COMPONENTS
The kit comes with a high pressure fuel pump that mounts on the chassis at
or below the fuel tank . For over 500HP and larger applications, an
ultra-high performance pump is required for an additional charge. Also there
is no need for a return fuel line although one may be used along with an EFI
bypass regulator. The return-less system is included in the kit but the
bypass style system is not included and can be purchased separately.

ECU & WIRING DETAILS
The computers dimensions are 6-inches long, 4.5-inches wide, and 1.65-inches
high; and it can be mounted either under the dash or in another dry
location. All wiring features weather pack connectors and are completely
terminated although you are required to install an o2 sensor bung in the
exhaust pipe. This can be done in one side only by any muffler shop and the
bung is included.

SYSTEMS AVAILABLE
There BossEFI comes in 2 sizes, 930 & 1200 cfm ratings. The 930 will handle
up to 650hp and the 1200 is good for 900+hp with the correct size injectors.
There is a simple formula to size the injectors. We use 4 so the math is:

HP divided by 2 /4 = injector size.

The computer is capable of very small pulse widths so it is better to be a
little large in this area. An example of this is 500hp/2/4 = 62.5lbs. In this
case we would use 63 lb injectors.For Dual Quad systems we would have 8 injectors so HP/2/8= injector size. 500hp/2=250/8=31.25. We would supply 8 32lb injectors in the kit. You can use this simple math to work up any HP combo you have. This is a Quick tip only,call us if you are un sure. All necessary sensors are included so
this is a true bolt on system!!

RELEASE DATE & FURTHER INFO
We will be sending out periodic emails with more details about the BossEFI
system up to the Spring 2007 release date. Please stay tuned, as THE MOST
EXCITING NEW PERFORMANCE PRODUCT IN 20 YEARS is about to REVOLUTIONIZE your
vehicle.

Thanks for your interest,
RetroTek Speed

Mark,

the fuel injectors hidden inside the fuel bowls & packaging the whole thing to look like a Holley carb is novel, but where this system breaks new ground for an aftermarket system is with the software. First it controls fuel pressure by pulsing the power to the fuel pump, simplifying the fuel system plumbing. Second it is self tuning. Up until this time, to my knowledge, only factory systems employed adaptive (self tuning) software.

"IF" this system works and is reliable, then conversion to fuel injection becomes a simple bolt-on proceedure, no more difficult than bolting on a carburetor. This is a big step for aftermarket FI.

One of 2 reasons I've been a big fan of FI conversions built upon Ford's EEC IV system is because it employs adaptive software.

Another nail in Holley's coffin, and a good company to own a few shares of stock in.

cowboy from hell
I typed a long post but when I submitted I got an error and lost everything I typed. Here is the short summary.

Ford EEC must be programmed to within 8% of perfedt for the adaptive to work.

Factory systems often run open loop since they use narrow band sensors

This system requires a wide band sensor

Wide band sensors are easy to damage and have a short life.

The carb look is unique and I have experimented with it myself trying for better fuel atomization.

If you want to run EFI, run real port efi and take advantage of the better intake designs like new cars.

Holley makes a good system with the commander 950 and is easy to install and tune.

Electromotive, FAST and Motec also make adaptive systems that use a wide band sensor.
