Huzhigeng already said, J-10 series will not use TVC. However, he did say J-10B is not the last improvement for the program.There was a report a few years back that said that the J-10B was going to use the Al-31FN-M3 TVC engine.
And since the first batch of J-10B will be entering production this year, I have a feeling that this engine will be for it specifically.
