DESCRIPTION
|
|
Analytune™ is an exciting new diagnostic service
provided EXCLUSIVELY by Power Hungry Performance. With
our proprietary software, we can simulate the the
operational parameters of your engine and generate
outputs in the same fashion that the ECM would construct
them. We can then use the data generated to provide 3D
mapping of your outputs which is useful in determining
how mild or aggressive your tuning is.
Frequently this service is
used in the forensic analysis of calibrations that were
being run at the time of an engine failure in order to
help determine if the calibrations may or may not have
been a contributing factor to the failure.
Analytune™ is just one
more step we use in providing the highest quality
calibrations available... ANYWHERE! |

|
WHAT ANALYTUNE™ CAN DO FOR YOU
|
- Simply send your chip or e-mail your calibration and stop worrying about whether your calibrations are safe
- Keep track of changes to calibrations for different modifications to improve performance and reliability
- Custom tuned files from any vendor are capable of being analyzed for safety and reliability
- Using scripts, we are able to simulate different operational conditions such as temperature and load
- Start of Injection (SOI) curves are often involved in engine failures and we can immediately identify problems
- Timing (SOI), Injection Pulsewidth, Injection Control Pressure, and Mass Fuel Desired output are available
- Problems with tuning can be immediately identified through the use of 3D mapping techniques
- Data is generated collected in the same fashion that the ECM handles calculations

** LEGAL NOTICE **
|
Our Analytune™ service is
intended to provide vehicle owners the means of having a
clearer idea of how the calibrations on their chip or
programmer are affecting their vehicle and whether or
not the calibrations they are using are reliable and
safe for any given application. In the process of
calibration testing, we will have full and direct access
to the binary data of any calibrations being tested.
This information is copyright protected and UNDER NO
CIRCUMSTANCES will we redistribute (either for free or
for profit) this information to ANYONE. Any copies of
calibration data used for testing will be deleted from
our system once our analysis is completed.
We do not provide customers with actual copies of any
maps as they appear within the calibration; what we
offer is a graphical representation of the PCM's final
calculations of these parameters under operational
conditions. Also, please be aware, it is not possible to
derive any of the IP used in building tunes by mere
observation or utilization of the data contained in
these graphs; no no third party will be able to view any
vendor's actual tuning maps.
When you purchase a product, you have specific rights as
to how you use that product, including the right to know
whether or not the product is safe for a specific use.
Some companies do not want you to use our service and
may even threaten legal action in order to prevent you
from having your calibrations analyzed. By accepting and
using our service, you understand and agree that you are
doing so by your own choice and that Power Hungry
Performance shall be held blameless in the event of any
dispute arising from the use of our service.

HERE ARE SOME EXAMPLES OF ANALYTUNE™ IN ACTION:
|
| |
|
Stock 2001 Calibration at 2600 RPM, 1/2 Throttle, and 180 Deg. EOT
|
|
|
This is a stock 2001 Automatic Transmission calibration being
tested at 180 Degrees Engine Oil Temp with the engine at 2600 RPM
and the throttle at about half. Under these conditions, the Start
of Injection (Total SOI Deg.) is about 15 degrees, Injection Pressure
is about 2100 PSI and Injection Pulsewidth is about 2.00 milliseconds.
|
| |
|
Competitor's Calibration for AC Code Injectors at same parameters
|
|
|
There is clearly cause for concern in this case when you look at
the Start of Injection value (Total SOI Deg.), which is 34.2 degrees
in this file. Even for a standard Split Shot injector, this would be
considered aggressive. This sample file, however, was for a Single Shot
AC Code injector which requires a significant decrease in Start of
Injection timing in order to run reliably. At full throttle and 3500
RPM, the Start of Injection climbs to just short of 50 degrees. Injection
Pressure has also risen to 2500 PSI which by itself isn't bad, but the
Injection Pulsewidth is almost 3.46 milliseconds which is more than
it would take to empty AC Code injectors at 2500 PSI, especially at
only 1/2 throttle!
