Interesting '89 Calibrator...

[Mike Frels]

A couple of months back I bought a 165 ECM out of an junked '89 Camaro. 
Last weekend I finally had a chance to test if it was a good working box. 
After removing the calibrator I took the blue cover off and saw something 
that puzzles me. the 16 pin chip of the two small chips has had the #2 and 
#15 leads cut. There is also a 10k resistor soldered across the #2 and #3 
contacts in the calibrator socket of the same chip. If this is the netres 
chip for limp home what would this modification accomplish?
