	I think what you want to do is disassemble the calpak and desolder
the prom

should yield 
	what you want. If its only temporary to do cal adjustments, you
might wanna 
	dissect a Sy/Ty calpak so you retain the proper backup fuel
parameters (I' 
	understand the calpak contains the prom, backup fuel chip and ESC
control..if 
	thats not called a calpak, excuse my terminology please.). Unless I
dont 
	understand what you want, in which case, forget what I wrote :-)
