How will cruise control and the manual transmission work? You really need an automatic to make full use of this cruise control as intended, right?
It will disengage anytime you push the clutch pedal; that way it doesn't "free spin up" shifting gears.
Say you had it set at 50; which would be 3rd or 4th gear, and you're stopped at a light.
You roll out like normal, shift to 2nd, and hit the cruise. It would accelerate, but when you pushed the clutch in to shift it would disengage, you shift to 3rd, hit the "Resume" on the cruise, it would come to speed and stay there; now if you want to drop RPM's, clutch in, cruise switches out, shift to 4th, hit resume; and you're set.
I know someone will ask about "I can shift without the clutch". Yeah, but that kind of shift also involves playing with the throttle; you lose that control and the engine would start heading towards the redline, and past. At this point, it's your call, disengage the cruise, or watch your motor go
