RevTech DFO How it works - Custom Chrome

RevTech DFO
Optimize your fuel injection without the need for expensive
dyno tuning! Developed by Mark Dobeck, the inventor
of the original Jet Kit, the DFO allows you to quickly dial in
your engine’s fuel delivery, whether on a stock bike, or with
freer flowing air filter and/or exhaust added. Installation
takes less than an hour, and adjustments are made by the
simple turn of a screwdriver. A little experimentation produces
results you can feel, whether simply removing a lean
hiccup or flat spot on your stock bike or maximizing the
effect of your aftermarket exhaust.
• Simple screwdriver dial-in
• Provides crisper throttle response
• Three range adjustable fuel delivery curve
• Compact size, only 31/2" x 11/2" x 3/4",
allows convenient mounting
• Simple, reliable, and excellent for expert
mechanics or do-it-yourselfers!
• New DFO HP provides additional tuning
capabilities for highly modified engines
How it
works
The RevTech
DFO modifies
the outgoing
signal from
the ECU to your injectors, increasing the duration of the
spray of fuel, thereby richening the mixture. Adjustable
pots allow you to add fuel where it is needed over three
areas of the rev range. A fourth pot allows you to set a
transition point from light-load cruise to high-fuel performance
mode. This allows both basic tuning and more sophisticated
fine-tuning for specific racing situations. The
transition feature also has a load sensitive function that
overrides the base rpm setting to allow an earlier crossover
whenever large throttle openings are introduced at low
rpm's. If, while operating in the light load/cruise mode,
the DFO detects a rapid opening of the throttle, a predetermined
amount of additional fuel is added to further
increase throttle response and acceleration beyond what a
factory fuel map will deliver.
“DFO eliminates the need for expensive factory re-mapping and quirky
downloads. Installation of the DFO only takes a couple of basic hand
tools and a few minutes for any V-twin using EFI”

“Tuning was finished on both bikes within a few blocks and couldn’t be easier. Both bikes
run perfectly all across the (r.p.m. range)”
HOTROD BIKES - Nov. 2002
“After installing the DFO, and spending about an hour experimenting with different
settings, we were able to eliminate the popping entirely, and smoothed out the throttle
response considerably (the bike already had a S.E. Stage2 download). The improvement
isn’t something you’d necessarily see on a dyno chart in terms of dramatic h.p. or torque
increases but it clearly made the bike a lot more pleasant to ride.”
