I think what you want to do is disassemble the calpak and desolder the prom 
thats there. then fab a custom socket thats "plug innable". That 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 :-)
