New! Element Hydra EMS 2.6 Engine Management
System New
with more maps, higher resolution, smoother interface, and quicker
tuning!
Complete control under all conditions!
Stand-alone systems have been around for many years but the difficulty in
finding good tuners, lack of tech support, poor base maps, difficult
installations, and expensive price tags have kept them out of reach of the
average consumer. Element Tuning has teamed up with Hydra
to deliver a superior engine management system exclusively for your car.
Systems that piggy-back the factory ecu for engine control can become
tiresome tuning. Hesitation is a common theme caused by rough
transitions as the two switch control from the factory ecu map to the
piggy-back map. With modern day “dynamic” engine management systems that
widely vary ignition timing and fuel tables, piggy-back systems can often
be difficult to tune as it is nearly impossible to stabilize the ecu over
a wide range of conditions. Knock under throttle lift and transitions
from the factory ecu map into the aftermarket ecu map can be difficult to
tune out without severely limiting performance under all conditions.
Element Tuning has revolutionized the stand-alone ecu with
plug-and-play practicality, excellent “stage” maps, an affordable price
tag, and technical support second to none. We have listened to your needs
and have addressed them with the release of our ecu.
Modern 3D Tuning Interface:
Window’s based software with easy to use pull down windows and easy to
read displays. 3D mapping allows you to quickly spot holes and rough
transitions in your mapping. Analog style gauges are easy to read
quickly and deliver critical information needed while tuning. Load
and RPM extrapolation feature allows for easier smoothing of the maps.
Large panel view option allows you to see
more of the 32x32 mapping zones for real time tuning.
Wide Range Mapping Zones:
Often aftermarket engine management systems lack resolution with only 10
or 16 load sites for tuning fuel and ignition timing. This often leaves
you using the same load site to tune a large range of boost pressures.
A 32x32 mapping area gives you 32 load sites for boost and vacuum,
allowing a wide range of fuel and ignition timing tuning. Partial
throttle, high boost, lean run conditions are a thing of past. Complete
control under all conditions!
Tuning Convenience:
Standard Windows navigation is intuitive and quick for tuning. Tired
of having to stop and upload changes? With Real Time Tuning
and Tracking (marks exactly what load site the ecu is using) you
can now make changes on the fly.
The Offline Tuning feature allows you to make changes to your map
without a connection to the ecu. Extensive data logging allows you to
review your tuning in comfort, make changes to the map, and upload them to
the ecu when it’s convenient.
Fuel economy:
Closed-loop fuel control utilizes the factory o2 sensor for
superior fuel economy under light load. This monitors the specified AFR
and automatically adjusts fuel metering to unsure the specified AFR is
met. For instance, if you want to run a 14.7:1 AFR under vacuum cruise
conditions, your map would look like this:
The ecu will automatically adjust the
injector pulse width to maintain the proper AFR of 14.7:1 and will apply
long-term fuel trims during the drive cycle. Closed loop can now
be mapped against rpm, boost, throttle position, and coolant
temperature!
Automatic Fuel Tuning:
You can enable the ecu to perform a closed-loop operation of the
entire fuel map with the Auto Tune feature. In this mode
the ecu will automatically adjust fueling to achieve the desired air fuel
ratios set in each load site. For instance if your goal is to run 14.7:1
under vacuum, 11.3:1 up to 12 psi, and 10.9:1 at 18 psi, the ecu will
automatically adjust the fueling to meet this criteria. The ecu will then
apply a “long-term” fuel correction and automatically correct your main
fuel map so that the “long-term” fuel corrections are kept to a minimum.
This feature requires the option
wide-band o2 sensor which plugs directly into the unit, requiring no
additional and expensive hardware. The closed-loop operating range is
adjustable for when it is not optimal to run closed-loop fueling.
Large Fuel Injector Compensation:
Even basic modification to car will push your stock fuel injectors to
the limit. Larger fuel injectors can often cause your car to stumble
pulling up to traffic lights etc as your factory ecu was not programmed to
handle this. We’ve added control for:
Injector response time in ms over voltage
Minimum injector pulse width
Injector phasing over 16 rpm ranges
Run low impedance or high impedance
injectors without the need for a ballast Individual Fuel Injector Trim
Individual Fuel Injector Control:
Subarus in particular are known to have problems related to a lean
running cylinder. Often fuel rails are recommended but they only increase
overall fuel and don’t address the problem of uneven air distribution to
various cylinders. We’ve added individual injector trim allowing more
fuel to be injected to the cylinder that’s running leaner than the rest.
Individual
Cylinder Ignition Control:
8
cylinder individual ignition trim adjustment.
Anti-Lag:
Used primarily for racing applications these can dramatically decrease
¼ times and reduce turbocharger lag. Less sophisticated versions of these
systems can cause excessive exhaust gas temperatures and lean run
conditions.
We’ve added both a fuel map and an ignition map that allows you to tune
specifically for when this option is engaged. You get the same 32x32
mapping resolution as your regular fuel and ignition maps. Complete
control under all conditions!
Optional Fuel, Ignition, and Boot Maps:
An auxiliary fuel, ignition, and boost table allows the user to create a race gas map based
on the main fuel, ignition, and boost maps. The user can lean out the AFR,
increase ignition timing, and increase boost on this table to an
appropriate race gas level such as 12:1 to increase power which can be
activated via a simple grounding switch.
These auxiliary tables can also be utilized to create a conservative
map based on the main maps. The user can richen the AFR on this
table to an appropriate pump gas level such as 10.5:1 to increase safety
margin which can be activated via a simple grounding switch.
Safety:
For when things go wrong and we all know they can when racing, a
backup spark map can be triggered to come online. For instance
if major knock events are recorded the backup map can be set to kick in
and drop your Ato a less aggressive ignition map
and a richer AFR to be utilized. The backup ignition map has the same 32X32
resolution as your main map.
Sixteen points of knock threshold adjustment for extremely fine
adjustment. This allows you to adjust the sensitivity of the knock system
over 16 ranges of RPM. The amount of timing pulled per knock account, the
maximum retard, and additional fuel compensation is user defined. Other
knock control systems just retard your ignition timing which can sometimes
make it worse as it causes exhaust gas temperature to increase
dramatically.
Sensor feed back compensation:
Coolant temperature: This uses your factory coolant
temperature sensor and allows you to globally adjust the fuel and ignition
maps to compensate for 16 ranges of coolant temperatures. The benefit is
to add extra fuel and adjust timing for when the car is running outside of
normal operating temperatures such as when coolant temperatures are really
cold or really hot.
Air
intake temperature: This uses your factory MAF sensor for temperature
ranges and allows you to globally adjust the fuel and ignition maps to
compensate for 16 ranges of air intake temperatures. The benefit is to
add extra fuel or adjust timing for when the car is running in a wide rage
of temperature conditions due to seasonal changes or desert weather.
Vehicle Speed: This uses your factory speed sensor for to globally adjust the fuel, ignition,
traction control, and boost maps. The benefit is to
optimize fuel, timing, and boost based on gear.
Knock:
Sixteen points of knock threshold adjustment for extremely fine
adjustment of knock amplitude. This allows you to adjust the sensitivity
of the knock system over 16 ranges of RPM. The amount of timing pulled
per knock account, the maximum retard, and additional fuel compensation is
user defined. Other knock control systems just retard your ignition
timing which can sometimes make things worse as it causes exhaust gas
temperature to increase dramatically.
If large amounts of knock are recorded, a backup fuel and spark map can be
triggered to come online for safety. For instance if major knock events
are recorded and exceed user defined levels, the backup maps can be set to
kick in and reduce ignition timing.
For cars
with noisier race engines the engines knock raw voltage amplitude can be
data logged to correctly determine the “knock threshold.”
“Tip in” or “Transition” knock:
Often sudden changes in throttle position cannot be quickly picked up
by the MAP sensor such as when shifting or lots of on-off throttle
situations such as road racing. Many piggy-back type ecus only use MAP
for tuning and will experience knock under these conditions. To combat
this, the “Throttle Pump” map adjusts fueling based on TPS at various rpm
points so there is no need to excessive retard the timing map.
MAF Sensor Limitations:
High hp Subarus often max out the MAF sensor requiring “large” MAF
housings which can cause fuel metering and load calculation problems.
Element allows you to run speed density alleviating these issues and opens
the door to run larger turbochargers with 4” inlets.
Running High Boost:
The factory WRX MAP sensor is really only accurate to about 22 psi so
included is a built-in 4 bar map sensor that allows tuning for up to
35psi.
Closed Loop Boost Control:
This allows you to set boost targets over rpm which will reduce
fluctuations in boost level due to atmospheric conditions. Other boost
settings allow you to control how accurate or fast you want boost
response. This type of boost control system is optimal for those parts of
the country that experience a wide range of weather conditions. The
Hydra even has gear based boost compensations maps to help level out boost
pressure fluctuations experienced in different gears. Additional
boost maps are used for TPS, Air Temp, Coolant Temp, and AUX map
compensations.
A separate boost limit map is also available
based on RPM to prevent overboosting. When the limit is reached a
fuel cut will kick in to help prevent engine damage.
Complete Rev Limit Control:
A user definable “soft” rev limit slows the engine down before the
abrupt “hard” rev limit allowing for smoother rev limit control.
Launch Control:
An adjustable “launch” control rev limit
is great for drag racing. LC is tuned through a 32x32 fuel map and
a 32x32 ignition map for maximum control.
Flat-Foot Shifting:
Shifting without having to lift off the
throttle is not only great for drag racing but also road racing as it
allows boost to be maintained between shifts, and for the rpm limit to
be programmed for rpm matching. FS is tuned through a 32x32 fuel
map and a 32x32 ignition map for maximum control.
“Dwell” Control:
Burned out coil packs can be caused by improper or the lack of “dwell”
adjustment. The “dwell” adjustment allows for the tuner to prevent coil
over-heating but allow for string spark a high rpm to prevent misfires.
For maximum performance at all rpms the "dwell trim" map allows for
fine tuning at specific rpm points.
Atmospheric Blow-Off Valves:
The Element ECU converts your MAF sensor metering system to speed
density which uses MAP and IAT compensation for its tuning platform
allowing you to run vent to atmosphere blow-off valves without the
bucking, part throttle hesitation, and rich conditions associated with MAF
sensor controlled engine management systems.
High lift Cam Compensation:
Many are upgrading there engines with higher displacement options
which often require high lift cams, large fuel injectors and large
turbochargers which can cause a rough idle. You can now perform a simple
fix by increase idle rpm by about 100 rpm to clean things up with full
control over idle speed.
A “Zero TPS Vacuum” control map also allows you to specify a vacuum
setting for the ecu to read when the throttle is closed to combat
fluctuating vacuum readings cause by “big” cams. This allows for smooth
delivery of fuel and a nice clean idle.
Closed Loop
Variable Intake Cam Timing:
Cam timing can be controlled and adjusted for optimal performance with
32x32 maps.
Closed Loop
Variable Exhaust Cam Timing:
Exhaust cam timing can be controlled and
adjusted for optimal performance with 32x32 maps.
“Staged” Maps:
If this all sounds a little overwhelming then our wide range of
“stage” maps exclusive to Element Tuning’s customers will get you up and
running quickly.
