sae?std?din?
http://dynojet.com/gmhtpmag3.shtml here explains SAE and STD. DIN is just the german measurement.
SAE
In the United States this is usually Society of Automotive Engineers (SAF) standard J1349 Rev JUN90. Correcting to SAE J1349 alters the data to make it seem as if it was taken when the atmospheric pressure was 29.23 in/hg., the temperature 77°F and the humidity zero.
STD
The older PEP software (v4.x) corrects only to SAE J1349. The newest WinPEP (v6.03) corrects to not only J1349, but to other standards, including "standard corrected," popular with aftermarket manufacturers (no doubt because it uses 29.92 in/hg and 68°F' to get bigger numbers), "EEC," used in Asia and parts of Europe, and "DIN," used in Germany.
