For the price of ther chip burner ($90-150) the price of the Zif socket and chip/s ($10-25) and the price of an OBD2 conversions harness ($80-150) you can burn chips for your car all day long with Uberdata. Your only problem would be finding some one to tune with it, and all you wold have to do if find some one who knows what there doing work with you on there side time, seeing as how shops are probably not going to support a program thats not licensed and all that. Basicly anyone who can read A/F ratio and set Fuel tables/maps.
The idea is you solder a zif socket into the ECU, then you have the chips that get inserted into the socket, so now you can swap chips without have to resolder and unsolder, aong with the benafit of a standlone EMS IE no piggy back method.
The hole despute about safc and vafc being a piggy back tuning device go back to the fact its an electronic device explaining to the ECU how It should work itself when really the ECU know how to work itself just its not set internaly to workth that way thus the SAFC. This way if you encounter problems etc. etc. you can trouble shoot with out having to think with a loop in your head or doubts about the engine management programing.
Thats a ruff explanation so please no flaming i was trying to brake mit down for him a little.
Ps. I know your likeing the way this thread took a turn slut
