Subject: Fel-Pro fuel injection system

In the May '97 issue of Hot Rod on page 141, there's a write-up on
Fel-Pro's new fuel injection system. 

It says:
"When it comes to computer technology, nothing stays the same for long.
The state of the art has a nasty tendency to expand and improve.  At least
that's what's happening at a new company called FP Performance.  Though
the name isn't familiar, the parent company Fel-Pro, should be.  Fel-Pro
is branching out and has moved into Electronic Fuel Injection systems.

FP Electronic's head man, John Meaney, is a pioneer of EFI.  He's the man
who founded Digital Fuel Injection (DFI).  His latest ventue is a new EFI
business and a new box intended for upscale street engines and all-out
race motors.

The most impressive feature of the FP Performance box is its ability to
work with an NGK, wide-range oxygen sensor tha allows tuners to enger an
air/fuel ratio into the software will result in extremely accurate,
closed-loop control over wide open throttle (WOT) air/fuel ratios.  In
concept, this is similar to current factory EFI boxes for closed-loop
control of the 14.7:1 part-throttle air/fuel ratio.  Unfortunately, the
factory oxygen sensors aren't compatible with WOT air/fuel ratio control
at, for example, a 12.5:1 air/fuel ratio.

The basic controller (with wiring harness) sells for $800.  The wide-range
oxygen sensor feature is a $400 option, and the base system can be
upgraded at a later date to sequential fuel injection.  For those who want
the whole enchilada immediately, FP offers a Sequential Electronic Fuel
Injection (SEFI) box for $1200.  Other features include one electronic
injector driver cylinder and bank-to-bank cylinder firing - where two
cylinders per bank fire simultaneously instead of all injectors firing at
once.  The advantage of the bank-to-bank program is more stable fuel
pressure.

The FP Performance box includes a waterproof case that controls the
electromagnetic interference (EMI).  The system also incorporates
individual cylinder timing and fuel controls (in sequential mode) without
the need for a distributor-less ignition system.  in fact, individual
timing can be incorporated with an MSD box.  All the software is
DOS-based, icon-driven, and can be run in a Windows shell.  There will
also be specific controls for two-stage nitrous (with one timer for both
stages) and a seperate ignition retard. 

The best attribute of electrnic fiel injection is that as computer
technology imporves, it will lead to less expensive hardware that "poor"
hot rodders like us can use."

There's also a few photos of the software screen-shots, the hardware
itself, etc.  One thing that's interesting is this statement regarding the
fuel map (where the value of the cells is the desired air fuel ratio),
"Instead of using a number to represent pulse width for the injector, this
map uses MAP rate (a representation of load) on the vertical scale, and
rpm value on the horizonatal scale.  This design makes tuning easier
because the map allows infitine command of the air/fuel ratio rather than
a guesstimate"
