Timing
Controller's Advantage
PowerCard's Timing Controller represents the latest in engine
timing technology. As the OEMs upgrade and improve their engine
management systems to comply with higher emissions standards, the
timing control method for forced induction systems must improve
for safe and powerful results. Timing Controller’s RPM based
methodology is the answer.
Timing
Controller's Methodology
Proactive timing retard is the safest method of avoiding
detonation under boost and PowerCard's Timing Controller is the next
evolution. Timing Controller’s breakthrough
technology marries RPM-based control with precise timing
retard. Previous timing control devices would retard the same amount
of ignition timing at High RPM and Low RPM. This compromises Low RPM
power for High RPM safety, since the amount of timing retard
necessary for High RPM is more than is necessary for Low RPM. NOW,
Timing Controller intelligently sections the RPM band into three
ranges - Low RPM (0-2600), Mid RPM (2600-5000) and High RPM
(5000-7000+), allowing for optimal timing
retard in each of three RPM ranges. Each RPM range is
independently adjustable to retard timing from 0-15 degrees with the
touch of a few buttons.
Why RPM Based?
The factory full-throttle timing curve of the Mazda Miata is
fairly conservative at low RPM, while being somewhat aggressive in
the midrange and at high RPM. This means that when we optimize the
timing curve for forced induction at Low RPM,
little and in many cases no additional timing needs to be retarded
for proper combustion and maximum power. As the engine RPM
increases, boost level, SC outlet temperature and engine efficiency
increases, especially on
engines with VVT,
and that requires a
|
different amount of timing retard. The Mid RPM range begins right
before 2800rpm (a detonation-prone area on VVT-equipped 01 and later
Miatas) and requires a moderate amount of timing retard. As the
engine enters the High RPM range it is breathing freely and
ingesting large amounts of forced air.
Maximum retard and precise adjustment are necessary at
this point and Timing Controller delivers.
Works with the
factory ECU
Mazda has spent millions of dollars developing,
testing and certifying the settings used for their ignition system.
The factory ECU can compensate for every change in elevation,
barometric pressure, intake and engine temperature. It is the
perfect platform on which to build. As with PowerCard's
fuel controller's, Timing Controller only goes into action when it
senses boost.
How It Works
Timing Controller is real time adjustable.
It doesn't require a laptop, a special connector or technical
knowledge. Timing Controller has 3 modes corresponding
to the three RPM ranges – Low (Green), Mid (Yellow) and High (Red).
In each mode from 0 to 15 degrees of timing retard can be programmed
by simply pushing the + or – button. Timing
Controller is wired between the factory ECU and the ignition coils.
The Timing Controller looks at engine RPM and when it sees boost it
immediately retards ignition timing to match your programmed
settings. If an adjustment needs to be made,
simply press the mode button until the desired RPM range is active
and make the adjustment. The changes take effect
immediately.
