In the AM, I will download the stored Cyl head temp. It is under 'warranty " in the autotune. Reads the ECM.  I am sure the stock ecm also stores this info.  Unfortunately, it will not save it to a log, I have to read it from the module only. 

Today we did about 225 miles.  35.7 mpg, 2 Up, about 345lbs total.  Highest temp was 235 on the oli. See above for the cyl story. Stay tuned on that.  It gives every minute of every day logged for all cylinder temps. I do'nt recall seeing anything over 330, but I will post it tommorrow.

This is for the autotune SPEEDO calibration.  It was set for 42000.  In the manual, which I just noticed, it is for bikes with 17" wheels.  The FLHTCUSE2 has 16" wheels.  Tat setting is 42450.   I noticed when traveling with Unbalanced, his GPS was always showing slower than indicated.  Now I think it is correct.  At 3000 rpm in 5th I am at 70. At 3000 rpm in 6th I am indicating 82-83. I think that will coincide with the GPS.

Rhino,

There is only one CHT sensor on the bikes, and that is the front cylinder. I have not seen anything over 292 on my front cylinder. If you saw something around 330, I wonder what the rear would be. My rear is running at least 40 degrees over the front, sometimes 60 or 70. The front is VERY consistent 285 - 292. The back is the one that moves around a bit.

To get the temperature of the hot cylinder, you will need to manually measure it with a thermal gun.

OK,  I cannot print or save temp data, so I did it one at a time:

Here are the stats.
Of all of the running time, starts and cruise etc. each time a temp is reached, it gives a temp hit.  For the folloowing I have hith these listed temps X times as listed below:

Total run time of bike:  53 hours
Total Starts:  38

Temp:

Since the temperatures that the ECM measures come from a different spot, rear of head, near intake port, than I am using with the RayTek, I decided to replicate your measurements. I set the scanner to measure temps and I went for a 10 mile ride or so, where I knew I could find some red lights. Nothing special, no traffic jams, just what I would expect to find riding around town on a Sunday afternoon.

When I got back, I left the bike running with the scanner recording temps while I shot the temps. I use the silver aluminum right next to the spark plug hole. I have found this to produce consistently hot numbers. I then looked at what the software recorded.

ECM recorded: 282 F
Front spark plug recess: 321 F
Rear spark plug recess: 382 F

I'm not saying this is an absolute, but it does show that the temperature measured by the ECM is cooler than what you will measure with an infrared thermometer.

Since I started this, I have been measuring temperatures in different places on the head, and got different readings as the spot changed. By using the spot of aluminum right under the plug, it gives everyone a good reference point to use for comparison. On the attached blurry image, youcan see the bright red dot in the middle that shows where I am aiming. I usually get in much closer than this, but this is just for demonstration.

This morning's ride was for a mileage check: all interstate, 6th gear, 72 mph, ~2700 rpm. I topped off at the station at the interstate ramp, rode 44 miles and topped off there. Turned around an rode back to the first station to top off again.

Trip up:

Air Temp ~60 deg
Oil Temp: 211
Front Cyl: 254
Rear Cyl: 325
MPG: 36.5

I leaned it out a bit in the cruise range where there is ample airflow and headed bact to the first station. Same speed, same everything:

Air Temp ~65 - 70
Oil: 220
Front Cyl: 270
Rear Cyl: 340
MPG: 38.5

Improved, but I should still be able to get better, running light and 1-up in 6th.

Chief,

What did you lean it out to and in what range?

Mark

[Chief]

Chief,

What did you lean it out to and in what range?

Mark

Mark,

2,500, 2,750 and 3,000 for 10% and 20% throttle.

I was originally measuring 13.0 rear and 13.5 front. Leaning it out brought those up to 13.5 rear and close to 14 for the front.

If we can develop a consensus on how much heat we can run in these heads, that will help determine cruise mixtures. Factory settings are 14.6 and then it gets leaned out more when it goes into closed loop.

I'm sure there is more cruise efficiency in there, but I don't want to push it.

I for one am waiting for Adam to respond. I will maintain the advantage with my autotune while I am still stock. As changes occur, I am interested to see how others perform also.  The apple game must be concluded before I take on Chip.

  Chief,
  I am getting the same type of temps on the rear head. I am set @ 13.00/1 overide on the Tmax. I am only getting 30-33 MPG.
  It would be interesting to see what a stock config bike like ours reads @ the rear head.
  The question is? Are our Bikes running ANY cooler at all with the Tmax/SE filter, ETC?

JR,

If you have the override set to 13.1, I think you are running ok, but you are then gonna be a little rich for cruise at 2300, for example, and you are giving up performance at WOT.  The map allows gradual changes depending...

The stock Tuner Map was set for 12.5 at WOT ranges, allows cooling fuel to be added.  At Low RPM, and cruising, the AFR varies from Zippers, from 14.7 to 14.1. That is where the economy is.  For whacking it, you need more fuel.  JMHO & hope this helps.

I just want to keep my motor as cool as possible. I don't care about fuel efficiency...to a point.


As I posted in another thread, one of the dealers I visit currently has 3 motors waiting to be replaced. Two were from SEUCs and one from a Dyna. All three overheated and took a chit...none had over 2000 miles.

[FLHRSE3]

I just may be the new high temp record holder, the temps were in the 80’s for the first time since I got my bike so I went for about a 75 mile ride after work and checked the head temp at the conclusion: 380 front and 343 rear.  I still have the wind deflectors on, so I would hope that was a contributing factor and it would not actually run this hot, my right thigh was cooking at stop lights.

That seems a little odd. Most of the time the front jug is cooler because it's getting more air.

You win, it was a contest to see who would be the first to identify my typo, can’t get anything past you (how was that for covering up the fact that I’m dyslexic).
