Hrmm,which means the new china made sensor reading diff value??but i observe the whole operation while they change the crank sensor...they didnt on the engine and only try so crank and start after they finish installing everything..cos i think regardless of where it is being made,they should(crank sensor)give the same reading rite??anwyays,its a a sensor to read the crank..and i think since the mapping is being controlled by the ECU and there is no way the ECU relearn during the swapping process,therefore it should have given the same result(performance) after installing it rite??ahh...kinda 
Not really. The readings may be off a bit, just a little bit. Yes, there's no way the ECU relearn during the swapping process, but if the crank sensor value is slightly different, the sensor may give different reading to the ECU. U understand what I'm saying?Let's say u're an English teacher (ECU), and u have a UK student learning English from u (Original crank sensor). Everything goes by smoothly, this UK student can absorb everything and can give u perfect responses when u ask questions (Smooth engine, no underpower-feeling). And then this UK student 'graduated' (crank sensor kaput), and u have a new Chinese student (China made sensor). This Chinese student, his English skills (crank sensor specifications) are somewhat poorer than the UK student (underpowered engine). He can barely understand what u're saying, and couldn't give perfect response when u ask him questions. So after some time u lower ur teaching pace to his level (ECU relearn) and then he is able to catch up more quickly.
