Default StreetTuner Wideband, LM-1 or other

Picked up a StreetTuner so I can tuner my car for 92oct (damn Cobb where is the love for the 92 j/k). Anyway so that I can make the best of it figured I would pickup some sort of wideband for it. From what little I have read it seems the LM-1 is the way to go since the ST will futuristically be get data from it. Any opinions, thoughts ect.

we are using the LM-1 O2 controll box with a bosch LSUM-4 (i think) to do testing for some research... we run at mostly steady-state condtions and log most data in the range such that there are not huge changes in AFR but accurate reading are important in order to determine what we are finding.... I'd tell you but we are under non-disclosure polcies from GM, NYSAETEG, as well as the University and someothers...

I can say that the LM-1 works great. it is nice to have the analog out to run to the DAQ board (or replce stock sensor voltage) also the RPM tap and data log are very useful to someone with out a DAQ board.

My only gripe is it ai kinda large... not that it really matter with the amount of other stuff we have in there... but in a suby it would be tought to hide if you were goin gto be using it daily to send a signal to a gauge or the ECU...


As a side note you shoudl NEVER run you wide band with otu a controll box... unheated sensor kill themselves VERY quickly.

Futuristically? The ST shipped w/ LM1 capability.
We also provided an API for free so you can build plugins for any wideband sensor that you like.

Sorry, I missed that, the only thing I found on the LM-1 was a mention of it being a future thing, this was in a post about the manual just prior to it's release. I just got mine via UPS today and have not read thought the manual yet, nor have a done the best job looking in here, cobb forums and other places. (Bad Troy) This was very much a spontaneous purchase from a fellow Nasioc member, which will undoubtedly lead to other spontaneous purchases such as a 20G, injectors and a fuel pump

The only API's the I even begin to understand are those for use with MySQL and PHP or Perl so I don't think I will takle writing an interface for say the Zeitronix (my other main choice)

So I guess with that if I am looking for the best current solution it would be LM-1 since the compatability is already there.
