[AMC-List] EFI AMC - Injecting the Big Dogs - [ ?wtf ]

["Brien Tourville" <hh7x@xxxxxxxxxxx>]

Everything for EFi or TBI is available in junkyards - cheap.

For my Turbo App. the 1227749 ECM is between 
$15.00 - $50.00 from www.car-parts.com.

The rest - harness / injectors / Throttle Body /
sensors can be had at Pick-'n-Pull or a donor
heap for under $250.00 .

The GM boys have .net sites that cover everything
from which harness to locate to pinning an ECM
for 8cyl. applications.

Learning curve finding sites & reading up is
about a month to know what does what and
what to look for.

Biggest pita is getting the Intake Manifold
modded for Injectors.

VW has screw in Injector 'bungs' - holders
where the Injector body fits into on the manifold.

Welding a thick alum. rod to the manifold -
cut it off - drill it out.

Aim the injector nozzle - the spray - at 
a 43 degree angle to the intake valve head.

So, you're out around $500.00 in parts
if you shop a used manifold.

The Offenhauser single plane looks better
than the Torker for this - just whack out
the seperator in the plenum - more area
to mount the Injectors on the mated runners
and the runners are shorter than the Torker
- give you better low - mid throttle response.

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 RPM?s. 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
