Our kicker mechanism from 2010 was the linear type using a lead screw and surgical tubing, and while the idea had merit, it was poorly executed. There was no shortage of binding on the system, and the CIM driving the lead screw would get very hot, besides the Jag faulting every 5 seconds, until we got everything tuned just right.. (Only to be knocked out of tune 30 minutes later!
)
Of course, the CIM has shown no sign of permanent damage, and just keeps chugging. Yay CIMs!
