Black top GT engine original ECU is 64k, if you have 32k for blacktop it is incomplete bin.
yes 3j501 and 3j504 are same hardware, just later revision of software.
the bin you should try is http://www.daj.cz/r/p10ecu2europ11/cervena.bin (the red ecu - eu_p10_primera_gt bin 32kb)
then change maf type to 22680-2J200
P11 Gt engine has grey or red injectors? if grey injectors then also change injector size from 259cc to 333cc
datascan will only work when ecu is in car. When the ecu is in the car, and the car is running, change the rev limit and test, do not switch off to make change.
Did you check battery voltage? And the black and purple wire plug was plugged in?
