2000 GT EECV VIN YYYYYYYYYYYY or HPTUNERSXXXXXXXX

when i read my friend GT 2000 with my mpvi2.

vcmeditor ask me at the end if I want to put a vin to write the file, then the editor automaticly generate a vin like HPTUNERS18451875DDEF

is it normal ?

If i enter the regular vin in the windows, the editor ask me the same at the end. IF i say no, i get YYYYYYYYYYY vin
