The Dyna 2000 has been a highly recommended ignition module
for late model Evolution motors for the past several years. Installation requires you
remove the original HD unit and replace it with the Dyna 2000 module. Setup requires
setting switches on the unit to select the advance curve, the rev limit, the pickup type
and if the coil is single or dual fire. Bike Tech recommends the advance curve be set to 1
( the most aggressive curve), with a 6000 RPM limit. Most bikes will use the stock HD
pickup type. The setting on the coil is dependent upon your coil. The timing is set on the
Dyna 2000 by setting the number one cylinder to top dead center, then adjusting the pickup
unit until an indicator light on the ignition module comes on. The process of installing
and setting up a Dyna 2000 unit should take less than 2 hours. The ease of installation
and ease of setup make the Dyna 2000 an attractive unit to use.
DYNATEK recommends the use of DYNA ignition wires with its
ignition systems. Bike Tech has experienced problems by not using DYNA wires. We suggest
you spend the few extra dollars it costs to get the Dyna ignition wires if you use the
Dyna 2000 ignition.
Installation of the Dyna 2000 on a 1997 FLSTF yielded some
rather startling data. The subject bike was basically a stock bike with a ThunderSlide Kit
installed, a Uni-Flow air filter and a set of Cycle Shack slip on mufflers on the stock
header pipes. As testing began, timing was checked to ensure it was correct and a baseline
dyno pull was made to compare to the results with the new ignition module installed. The
base run yielded 59HP and 74 ft.lb. torque. The stock HD module was then replaced with a
Dyna 2000 module. The settings were advance curve 1, 6000 RPM limit, stock pickup and dual
fire. A second pull was made to compare the results. Much to our amazement, the maximum
power went down. Testing continued on all 4 advance curves. Curves 1 and 2 provided
virtually identical results of 57 HP and 72 ft. lb. torque. On curves 3 and 4, HP dropped
to 54 and 69 ft. lb. torque.
The test results below clearly show the results. The stock
curves show the 5250 RPM limit cutoff. The Dyna 2000 runs show HP curves pulling to 5800
RPM. The results of the test are clear, the Dyna 2000 module hurt the
performance of a 1997 bike. Bike Tech is aware of similar drops in horse
power when installing a Dyna ignition on a late model sport bike. Dyna Tech seems to have
some problems in delivering improved performance over stock ignition systems for late
model bikes. Dyna's track record in the past has been excellent. Bike Tech can only
assume that the problems noted will be fixed in the future. In the mean time, "let
the buyer beware".
Bike Tech does have a theory of what may be happening.
There is some circumstantial evidence that Harley-Davidson changed the advance curves of
1997 ignition modules. This information may be collaborated by the fact that HD released a
new series of Screaming Eagle 6000 RPM ignition modules that are California Air Research
Board (C.A.R.B.) approved. Harley-Davidson's need to meet Federal EPA regulations and the
stricter California standards for its motorcycles and parts tend to indicate that HD could
provide a module with the stock 5200 RPM limit (as provided in the past) and capture some
of the after-market with a new 6000 RPM Screamin' Eagle module. If the advance curves are
the same, no additional testing would have been required for the C.A.R.B. approval. HD's
research into performance have yielded a wide variety of Screamin' Eagle parts. Many of
these high performance parts perform better than or equal to any of the after market parts
available. It would not be unreasonable to think that Harley-Davidson has managed to kill
several birds with a single stone. A better performing stock ignition, an aftermarket
ignition module and EPA/C.A.R.B. approval for both products.
For other 1995 and older bikes, the Dyna 2000 is expected
to provide improved results. Bike Tech's testing of a Dyna 2000 on a 1994 engine yielded
better results. This bike did experience increased mid-range power over the stock
ignition. It must be noted that the Dyna 2000 did not yield a higher maximum horse power
figure than the stock module. This is to be expected since maximum advance on both
ignitions was the same. The more aggressive advance curve of the Dyna 2000 provided the
extra power in the low to mid-range (1500 to 2000 RPM).
