ACCEL/DFI
Gen 7.0 Performance Engine Management Control
System and CalMap 2000 Software
|
 |
| ACCEL/DFI is proud to
introduce the all-new next generation of
Electronic Spark/Fuel management systems, combined
with the all-new CalMap 2000 Software. Over two
years of research and development have resulted in
this new ACCEL/DFI Gen 7.0 system which raises the
bar in state-of-the-art aftermarket performance
engine management systems. With over 12 years
experience with engine management systems,
thousands of units in the market, our excellent
installation channel through our EMIC program, and
a continuous factory technician training program,
ACCEL/DFI is the leader in aftermarket fuel
management systems. |

Features &
Benefits
F: Water-resistant enclosure and main harness
connections offer options in mounting location for
the Gen VII Electronic Control unit.
B: Can be mounted in the passenger
compartment or under hood.
F: New electronic
circuitry design with noise-hardened protection
B: Each circuit is protected against damage
caused from short circuits or wiring that rubs
through the insulation in the harness, eliminating
costly repairs and keeping the smoke inside the
ECU where it belongs.
|
F: All-new CALMAP 2001 PC
windows-driven calibration software
B: Provides fast, user-friendly access to
all fuel and ignition related tables |
|
F: Software Selectable
Ignition Compatibility eliminates the need to have
your ECU modified by the factory because of
ignition upgrades . The Gen VII ECU can understand
and process signals from GM HEI and Opti-Spark
Ignitions, Ford Thick Film Ignitons, Fixed Advance
Magnetic Pick-up ignitions, (both Flying Lug and
Flying Magnet), and Fixed Advance Hall-Effect
ignitions.
B: Less inventory needs to be stocked to
cover applications. Possibly more important, if
your Gen VII controlled LT-1 is having troubles,
there is a way to check if your Gen VII ECU is
related to the troubles. It is possible to borrow
a Gen VII ECU from your buddy’s Mustang, use
CALMAP 2001 to download your entire LT-1
calibration into his Gen VII ECU, and now you have
another ECU that will run your LT-1. |
|
F: New Volumetric
Efficiency-based fuel tables
B: Offers increased resolution and control.
Volumetric Efficiency tables can be adjusted a
single point at a time, a portion at a time, or
completely increased or decreased by a percentage
with a few strokes of CALMAP 2001 software. This
vastly improves time needed to calibrate your
Volumetric Efficiency map. (Volumetric Efficiency
maps are the main fueling tables in CALMAP 2001). |
 
|
F: CALMAP 2001
offers a Volumetric Efficiency (Main Fueling
Table) Estimator.
B: This function allows the starting point
of your Volumetric Efficiency table to be
calculated by CALMAP 2001. Simply answer the
questions CALMAP 2001 asks you about your engine,
and CALMAP 2001 will give you a calculated
Volumetric Efficiency Table as your starting
point. No more "wild guesses" to
determine start-up fueling.
F: Software Selectable
Fuel Injection Modes.
B: With CALMAP 2001 the Gen VII ECU can
fire the fuel injectors in the following modes.
Sequential, Bank-to-Bank, Batch, or Staged Batch.
Sequential is only recommended if the Gen VII ECU
is provided with a cam position signal.
F: In Sequential mode, CALMAP 2001 allows the
adjustment of fuel injector timing in relation to
cam position.
B: Increased power output, lower emissions,
and improved driveability.
F: Individual Cylinder
Fuel Trim is possible in all modes of injector
operation.
B: This function is used to compensate for
intake manifold distribution inadequacies, poorly
matched injectors, or a combination of both.
F: Gen VII has Self
Diagnostic Capability with a provision for a
Malfunction Indicator Lamp.
B: CALMAP 2001 will display what the
trouble code is and what action the Gen VII ECU is
taking because of the trouble being sensed. A
Malfunction Indicator Lamp can also be
incorporated which will flash the number of the
trouble code.
|
F: Every Gen VII ECU has
the capability of operating up to 3 stages of
Nitrous Oxide.
B: Gen VII can calculate the amount of fuel
enrichment for each stage, and allows the end user
to trim fuel enrichment and ignition timing retard
throughout the RPM range that the nitrous will be
energized. |
 |
F: New graphical
"on-line" high-speed data recording for
up to 30 minutes of data recovery.
B: Data recordings can be replayed in real
time, can be stepped through point by point, and
can also be replayed in the Volumetric Efficiency
table. |
  |
F: Every Gen
VII ECU has internal altitude sensing and
compensation capability.
B: This function improves power,
driveability and fuel economy on vehicles when
they are driven to different altitudes. |
F: Linear or so-called
"Wide Band" O2 capability.
B: This option allows closed loop control
at all conditions and allows the end user to
select the air/fuel ratios that are desired at
different rpm/load points. |
 |
F: Gen VII offers two
separate rev-limiters. One is an ignition
rev-limiter, the other is a fuel shut-off rev
limiter.
B: The ignition rev-limiter can be wired
through a trans-brake or line-lock button to act
as a starting line rev-limiter. Both rev-limiters
are adjustable in 50 rpm increments. |
|
F: CALMAP 2001
offers "Help" screens.
B: If a user is unsure of a screen they are
looking at, they can simply push the F1 key and a
verbal description of the screen
being viewed will appear. |
