Check this out!
I was at work talking with the head research engineer at our facility. We manufacture Thermistors, which are temperature sensitive resistors. Ok here is what transpired:
He had a couple of automotive parts on his desk that I was ripping on him about saying that he didn't even know how 1/2 of them work. Him and I are good friends, so we are always jerking each other around. Anyways I commented to him that we should find a way of manufacturing Wide Band O2 sensors for a cheap price. After explaining to him how they work and the benifit from having them to tune with and also the explination of how many individuals would buy them if they were a reasonable price ~150 bucks or so. He became very interested and started asking more questions. Well here is what we got to. I also mentioned that many of our components are temperature sensing equipment and that maybe a EGT (exhaust gas temp) sensor would be more up our alley. Well he about jumped out of his seat and began explaining that this coming week they are to build 10 prototypes of *very high* response, very accurate heat sensors (good from 25*c to 1000*c). They are experts at developing devices with very accurate results and very quick time response. Our cars probably have several in them already, ie, manifold temp sensor ect. He explained he would be very interested in building 1 more of these sensors for me to put in my exhaust and have the electronic techs build me a way of recording data just as our scanners do. I explained that we should get the sensor installed and get it logging, then take the car to a dyno with a WB o2 sensor and chart the exhaust gas temp along with the WB reading and try to relate the two back to Fuel ratios for a tuning device. I realize that guys already use EGT devices for that exact purpose, but perhaps as we spoke we could provide this tool at a very low cost. This would allow us all to have a very accurate way to tune our cars. Just as a WB o2 sensor would. Obviously there would be other issues that would need to be oversome such as placement in the exhaust and what not, but its still incouraging.
We are going to chat with my boss to get the final approval of the testing and then we will get the sensor installed and logging equip developed and then I get to take my car to a dyno several times to get some runs at the companies expense! Can't beat that! I will let you all know how things unfold.
Later.

I will put this in the ECM secion as well..I think people there would have some interest too. Hope that is OK
