I have tire temp info in i2Pro, not close to it this week. Will dig in next week and forward if I find it.

If you are considering the Texense, you should talk to Pierre. He may be able to help you out with some data. You might talk to MoTeC directly or through MilSpecWiring.com. They sell the sensors and may be able to provide some data so you know what you are getting.
In case you haven't seen the prices on everything, here is the milspec page https://milspecwiring.com/store/inde...path=47_313_80

Peter: You give me too much credit. I'm not interested in MatLab and am trying to simplify the workflow. A simple workflow can be done often and without investing too much time. I hate spending hours trying to render a movie of a race.
Anyone have some data to share from Izze or Texense sensors in i2Pro?

Very nice. Can you display the same in vs distance instead of time?

Since there's no lap comparison, the time axis is interesting.
Watching the build up and decay of each corner, relative to one another, is fascinating.
Thanks for posting!

I really depends on what you have available for help and your style. I personally like the large memory units from Longacre or Intercomp that will record 3 temps each tire and hold multiple sessions. But, they take a little training to use and if you are relying on volunteer help, it might be too much. These units are http://www.intercompracing.com/memor...-135-l-en.html or http://www.longacreracing.com/produc...Tire+Pyrometer This one looks good, but it hasn't been released yet http://www.longacreracing.com/produc...Tire+Pyrometer
If you are having "unskilled" help, the standard single temp probe unit like http://www.intercompracing.com/delux...-136-l-en.html or http://www.longacreracing.com/produc...nomy+Pyrometer
I have and like the combined pressure and temp gauge http://www.longacreracing.com/produc...alve+0-150+psi They make one without the temp compensation as well.
Finally, if you don't get a memory unit, one of the best tricks is to put a piece of gaffer or racers tape above each tire. Then, when you come in and take pressures and temps, write them on the tape with a sharpie. That way no need to remember them or forget the clipboard, etc. You can also put the starting pressures so you have a good log that can be copied to your notebook.
As for notebooks, there are a couple of good apps in development that will record all your tire related information (pre and post session), but they are not ready yet. Some of them will also offer wireless recording, so no data input!

Hahaha! TomW, this would solve some critical questions for you, for sure.
That said, about 6/10 of 1% of my club level and DE drivers equip their cars with sensors and actively utilize this info, and about 30-35% of the entry level pro teams... About 75% of the top level pro teams use this capability...
While I think the Izze sensors will make this more accessible for DE and Club Racing drivers, there are still many, MANY more areas to mine for useful information to improve performance.
I put IR temp and TPMS information in the same category for many as simulation testing (using Simulink, OptimumG or Bosch simulation software).
To combine all three (shock pots, IR temps for tires and brakes as well as TPMS), I would equate that level of commitment and work to (relatively) inexpensive WindShear wind tunnel time and/or 7-post or 8-post shaker rig time.
It's all relative. Interacting with hundreds and now, probably thousands of users of systems capable of this, so few have the time, inclination or resources to embark on a full-blown engineering program.
It's all well and good to glom onto this level of information gathering and analysis, certainly Matt and I have an affinity for that, but the REAL issue is that once you HAVE this information, THEN WHAT are you going to DO with it?
