I just got a UTEC and I have been playing with it for the last couple days. How the heck do you log the readout from the stock O2 sensors? I am NA so they should work just fine for tuning. If you can't do it, why? It wouldn't make any sense.

I also got the UTI software, and so far I am pretty happy with it. It sure blows the POS TXS hyperterminal crap out of the water.

 

Answer is NO. You need to feed the 02 voltage to Utec and the only way is to get a Tuner or a third party standalone WB like Innovate, AEM..etc.

 

That seems silly. Aren't the stock o2 sensor signals traveling through the UTEC to get to the stock ecu anyway? I mean, if the utec can tell you everything else about the car (MAF voltage, TPS, coolant temp, etc.) then why wouldn't it be able to tell you what the stock o2 sensors are reading? Is it just so that TXS can sell you the "tuner" for hundreds of dollars?

I am planning to get an AEM UEGO anyway and link the two with using UTI, but for now I am just trying to learn the ins and outs of the UTEC while NA and this part has me confused!
