While I was surfing thru my DTT log data, I wondered just exactly what is the ideal head temp?&nbsp\\; Mine is hanging around 110-120 at constant hwy speeds of 70-75mph...
&nbsp\\;

 

200 to 260 degrees F.

 

Head temps of 110???????????????&nbsp\\; What are you measureing and how????

 

Sorry, I was a bit vague there....&nbsp\\;\\\\\\; 110-120C, or 230-250F..
I'm utilizing the stock head temp sensor thru my DTT programming, which is located on the front cylinder head beside the intake port.

 

AHHHHHHHHH.....230 -270 is fine....it's air cooled, remember!

 

Thats about the same as what I am getting on my 07 UC. What does you knock sensor data look like? I had to take 2 degrees out at 2500 RPM at about 15 % TP.

 

After completely warmed, 103* outside air temp, immediately after stopping temps on the head at base of spark plug were 318* front and 348 rear.

 

If this question is directed to me, I wasn't aware I could access knock sensor data..&nbsp\\; I do have pinging from 2 to 3K.&nbsp\\; I have pulled on degree so far and richened up the mix.&nbsp\\; The pinging is gone from 2.5K up now at full throttle, so I'll try pulling another degree from 2 to 2.5K.
