That's another good question. Here's the skinny...

Edge has recently restructured the part numbering system and have gone away from the 3 letter/4 digit coding they used to use. I'm not exactly sure what the reason for the conversion, but the numbering system actually works pretty well. 15xxx is for Fords, 14xxx is Dodge, and 13xxx is GM. At least I think that's how it goes. Anyway, there is no difference in the units... it's just the part numbers.

NOW, with that out of the way I will tell you that there are 2 different hardware platforms for the Evolution. These are easily identified by the version numbers.

The older version has a number that begins with E3 (ie. E3.17.22) and was built before March of 2007. These programmers come up as "Type 2" in the Pegasus software. (Type 1 is the original "Game Boy" style handheld units.) These are also identified by the OBD-II cable which does NOT have the 4-pin connector for an external sensor either on a pigtail or molded into the connector itself.

The newer hardware begins with v2.1 and is currently up to v13. These are manufactured after March of 2007 and come up as "Type 3" in the Pegasus software. Early versions of the OBD-II cables have a 4-pin connector molded into right side while later versions have a separate 4-pin pigtail to that can be used to connect to an optional external sensor.

The older versions have a final release of E3.22.28 (Firmware 22 and Calibration 28) and are no longer actively updated unless there is a drivability issue. The newer versions are updated as needed to include more recent calibrations and firmware fixes as they become available.

All the Gryphons we sell now use the newer hardware platform and are updated as need to include new features and firmware fixes. This hardware platform is stable and we've had very good success with it.

I hope this helps.
