Was looking for ways to make some changes to the 16263494 ecm for 2001 s10 blazer. Is there a way to remove a chip and socket or is something like roadrunner required? I really only need to change a thing or 2 so i dont need to datalog or anything

If I recall correctly that's the 2.2L 4-cylinder PCM? If so, I do not know of any "free" tool to make the changes with-you'll need an OBDII tuning suite like HPtuners or EFI Live.
If it's the V6 4.3L, then it should be an 0411 PCM, and you *could* use 24x7's flash tool, and Tunerpro to make your adjustments. It's dangerous, as there are zero safety protocols in effect, and if you click something wrong it will brick your PCM, but it's out there. Soon there will be a better option, but for now there is nothing else outside of HPtuners/EFI Live that is currently available for purchase.
Your best bet is to send the PCM out to someone who can flash it, and tell them what you need changed, if you only need one or two things changed. (unless it's fueling, which is going to need datalogging, or timing...or warmup/startup, etc)
i have tune those PCMs with HPtuners, S10 2.2 no problem.
Its a 4.3 v6.

I have TunerCats OBD2, I'll need to check to be sure I could reprogram the 16263494. Likely I'll need to make a bench flash connector if the 16263494 is supported by TunerCats OBD2.
TunerCats OBD2 is still available, but requires the purchase of a Road Runner PCM.
