What does it mean (in dynojet canned map) when knock control is ignored? Why is it ignored? Does ignored stop you from changing the value?

A 50/50 mix of acetone and ATF is a v. good penetrate.

   The 120R has notoriously heavy valve springs and the service life of a set of lifters should not be pushed beyond 30,000 miles.

weld a flat washer to the stud first then a nut to that much easier to get a good weld on the stud.  Bob

Forget to mention I just installed the auto tune module, with the o2 sensors. I couldnt get it to work, it was telling me the attempt failed

If you've just installed the PV map, reinstall the stock tune to see if it persists. Global adjustments are like throwing a dart blindfolded. Unfortunately with no o2 sensors makes it hard to see what's going on.

Possibly a failed temperature sensor.

Hi- I have a 03 ultra thts running rich! the front jug is blowing blue smoke! I pulled plugs and they are black! I have powervision1 tuner, I subtract 5% and little change, then the motor just stalls out! Any thoughts on why its running so rich, and what to do with tuner to adjust? I have an improved stock map in the pv1

A common issue
