Likely no since this is a hardware issue. There has been speculation the dct shifts down so fast that it exacerbates the issue (so unless they completely destroy the way the dct shifts), likely it can't be fixed via software.
Also there has also been speculation that it's due to more things on the s55 being run off of the timing chain such as the water pump and two hpfps vs. 1.
