The stock ECU did come with the engine, but re-flashed to get rid of all the extra shat not needed to run in my application. Basically, it was stripped down to the vitals for smog, a/f and transmission management. To be smog legal, it is necessary to run the same model transmission that came from the factory. They plug into the diagnostic port and check for that. So long as the smog equipment and programming is present and the truck passes visual, the ref will supposedly sign off on it. I guess time will tell...
