Default Cylinder head temps??

Any tuners know what the cylinder head temps are, as recorded by SERT? What is normal operating temperature range, and what is max temperature? I am considering doing more tuning on my 06 carb1200 Roadsterand use a infared thermometer to measure head temps. But it varies at different locations. I was wondering if using the infared temp guage on the same location as the temp sensor on FI bike would give similiar readings, or how far off they would be.[/align]

I've found the inferred will read 50 degrees hotter than the ECM temp sensor

I think that's a bad generalization to make. If you point the IR at the same location as the temp sensor, it reads about the same. If you point it at the exhaust port area of the head, it reads much hotter. It all depends on where you point it.

Well Frank here again you have to be 10% smarter than what your working with....if you want to know the temp of the combustion chamber you got to point the thing at the combustion chamber not the pipe of the side of the heads.......

Wow, who p***ed in your cheerios? The OP didn't ask how to get the temp of the combustion chamber. He asked:

Notice he specifically stated measuring in the same location as the temp sensor. Your answer is too generalized to apply here, and I stand by what I said.

BTW, there's no reason to get offensive in your reply. Just because I disagree with your answer doesn't mean I'm calling you stupid (as you've implied to me).

Default RE: Cylinder head temps??

I looked at a FI1200Sportstertoday. There is an electricalwire going through the hole in the top of the rocker cover of the rear cylinder directly center of the head. I ASSUME that is the temperature sensor. I can point the infared tempguage down there and get a reading, but I have no idea howaccurate the reading is compared to the SERT reading.

So then the question becomes if anybody who does SERT tuning can use an infared temp guage at a specific point that can be described to people like me who have an infared temp guage and correlate its temp reading with the SERT reading.

You guys can squabble all you want, but it will take someonewith SERT tuning exprience to answer the question.

First off Frank I can care less if you do or don't agree with me. I do care when you bring the VTF attitude over here.....God knows if your not political correct with the spelling or punctuationor your shoe is untiedthe VTF will certainly let one know.

As far as being offensive....I replied to your response tactfully and to the point.....if you had 25 to 30 emails from members here each day along with 10 to 15 maps and graphs to view from members each day, your answers would be short and to the point too.

I don't have time for these Internet aurguments....I left the VTF because of them and now you want to start it up here....sorry I not playing those games anymore. I suggest you use your Block button as I will on you.

Tho doc's answer may appear flippant to the casual,he probably has given as accurate an answer as is possible.Aimed at the combustion chamber is avg. 50 degrees diff.
any closer accuracy is probably not going to affect the outcome of what ever calculation you are attempting.
I would hazard anoother guess and say that one could log SERT data and extrapolate the SERT data by comparing the infared data and inputing incrementaly until the changes were verifiable......but thats another story.
I am curious what you are trying to emulate/simulate.
