black box ecu question

[dsmfever]

im wanting to use the black box...i understand the whole harness issues, i have tactrix 2.0 setup and ecu flash. where would i get the stock ecu image that i could flash on the car. can i do this with a data logger from the stock ecu? to me this is way more cost effective than dsmlink. any help would be appreciated...mod: 560cc, td05 20g(20lbs peak boost), 2 1/2 charge pipe with front mount, 3" gm maf and translator 2.0
