Yeah its cool stuff. Whats interesting is that I was always under the impression that the speed of the reading solely depended on the controller, until you get to incredibly small time steps and had to start thinking about molecular interaction style scale. I also swear reading that the ngk sensor was more accurate than the bosch lsu because the lsu is based on a narrow band sensor where as the ngk is a ground up afr sensor. And the stuff I saw put the bosch sensor (with any controller) at ~.1 afr (but worse the further you got from lambda) and the ngk was more accurate than that. I dont remember where I saw this testing done, it was some academic journal article I stumbled across searching for something else. You work there so you know better than I on this one probably. I do know that this year I plan on dyno'ing the race car using a handheld with an ngk sensor, cant remember the brand, but still running the lc1+bosch lsu and egt probes on the car to control closed loop.

Molecular interaction? You crack me up sometimes leafy.. Lol

The Bosch lsu 4.2 works on the same principal as the NTk sensor. How exactly are you going to use a NTk sensor on a hand held?? Interested....

The Bosch sensor is not based on narrowband technology, narrow is switching Bosch has a detection cell just like any other wideband afr sensor..

Its what one of our sponsors said, on the hand held part.

They may use our sensor on a handheld unit, however that says something If they don't use their own technology... Also not aware of a handheld unit that uses our sensor, that we know of anyway. Pictures or links of said device?

I clarified with him, not a hand held, afm1500.
