Finally!  We are really proud to offer the most complete diagnostic, and tuning tool for the Porsche 944NA, and 944Turbo.

The beauty of this setup is its ease of use.  The logging cable is native USB (no serial-2-USB converter headache), and only requires two wires to be installed into the DME harness!  Our logger reads the new diagnostic data routines, written by Rogue Tuning, and feeds the data to your PC.

The system logs all of the sensors that the DME has access to, and other important information as well:

• AFM / MAF voltage
• Boost pressure (951 only)
• Load (944NA only)
• Coolant temperature
• Intake air temperature
• FQS position
• Idle switch
• WOT switch
• NBO2 rich / lean
• Closed-loop function
• Fuel-cut operation
• AC compressor engagement
• MAP select (951 only)
• Ignition timing advance
• Injector duty-cycle
• WBO2 AFR*

*A separate WBO2 controller and sensor is required, with a 0-5volt output, which needs to be fed to the DME for logging ability.

The logger will cut down on diagnostic or troubleshooting time immensely.  No need to measure each sensor by hand with a multi-meter - instead you simply hook up the logger, and see what it shows you in real-time:  what is your coolant temp?  Don't remember what FQS position you are on?  Unsure if your TPS sensor is working?  Easy - just pull out the laptop, and start the logger!

Moreover, this becomes a benchmarking tool!  By measuring MAF voltage, users can compare their cars HP output.  Since MAF measures actual airflow, the ability to quantify mods is immediately possible.  Did that intake manifold upgrade actually make more power?  Compare before / after runs with MAF voltage; if the after run is higher voltage, then it did make more power.  Does raising the boost pressure make more power?  Check MAF voltage.  There is even some bragging rights here; for example if my car's MAF makes ~3.35 volts peak, and your car makes ~3.60 volts, then your car is undeniably flowing more air, and therefor it is making more power!

And as the name suggest, the logger will also allow you to save data to your laptop (laptop must be hooked up to save data).  This allows you to log while you drive, then review the data at a later time.  Furthermore, you can export the data to a comma-separated value (.csv) file for use in a spreadsheet application.

Here is a short video showing an early version of the logger on my personal 951:

951 Logging - Rogue Tuning DME Logger

*Rogue Tuning software only*

The factory software does not have a serial data/diagnostic-stream.  We wrote our own diagnostic data-stream, which does mean that the logger will only work with Rogue Tuning software.

Graph Output:

These are the differ displays available for the logger. There is the Dash, which shows a maximum amount of data in an easy-to-read format.

There is also the option to graph, in real-time, selected data. This extremely useful for identifying trends or visualizing data over time.

Small & easy to install:

The logger is about half the size of a deck of cards.  And with the supplied long cables, make it easy to route where it will be convenient to access.
