    NGC4 TCMs- Can we change the OS?

    I have been tuning these in house for a while now, and one thing the drive me nuts is that the majority of the OS for these things refuse to stay locked on the 4-5 shift. Even with the 4-5 Pull In Time reduced to zero in the tables if they are available (some OS don't have the table). We have found a couple OS that work really well and will not go into partial unlock during the 4-5. Is there any way to essentially clone those? Like I would love to have a template that superimposes the OS as well? Or should I try to talk to some rebuilders that can flash the "most recent updates" to see if they can at least flash the right OS in my cores?

    Any help here is greatly appreciated.

    PM me the calibration number that you need and I can test here and let you know. I have a bunch of new TCMs sitting on my shelf
