Question about ECUs

I have a chance to get a nistuned ecu for my turbo build. My question is whether it is compatible direct plug and play on 2000 1.0 k11 coilpack car which has been engined swapped to a cga3de 1.4 The car runs fine with the 1.0 ecu. The 1.4 car which I got the engine from had a bosch ecu so I couldn't nistune it(plus i put it on its roof).
