Anyone Used The Newer Athena Gpa Ecu?

It looks like the older "GET ECU" from Athena (that I believe was a direct ECU replacement?) has been replaced by a "GPA ECU" that is a piggyback unit.

Is that correct? Does that unit still control ignition and fuel mapping? Is it tuneable? Are those blue "special connectors" splices that attach to the stock wiring?

It's about half the price of the Power Commander so I'm curious what people's experiences have been. There's so little information on their website.
