Ignition Tuneup Info?

[cardoc]

I have used the ignition tune up times for years and they have stopped in the system. Or at least changed to where I can not find even the spark plug estimator times, Plug wires, General tune up info. It used to be there. Where did it go? Help me find it. Please and thank you!

It is under 'Engine Performance > Tune-Up'

Not on all car that's my dilemma. On some yes. I had two estimates this AM. One was there and the other was not.
99 chevy 3500 J motor not there.
04 jeep Cherokee Laredo its there
Spotty!!! Need the info on all cars.
