With Analytune™, you not only receive the assurance that your calibrations are going to be safe and reliable, but you can also have any of your existing tuning from us -- or other vendors -- analyzed and graphed.  
Analytune Calibration Analysis
Please See Price List
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!

  • 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
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.
Stock 2001 Calibration at 2600 RPM, 1/2 Throttle, and 180 Deg. EOT
Analytune - 2001 Model Stock Calibration
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
Analytune - 2001 Model Modified Calibration
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!
