Default a/f ratio

hooked up a pro logger wideband last nite and when comparing the log from it and a log from datamaster the a/f is different, the prologger reads down to 13.2 at wide open and the datamster puts the millivolts on the 02's at 950 ish, which one do i need to tune by?

They may not be that far apart, if I remember correctly, 0.950mv is 13.0 AFR. Others will chime in and correct me if I am wrong. Also 0.900 mv was about 13.2 AFR. If those are correct you could split the difference and call it 13.1.

go by the wideband, i have seen that typically ls1s like it around a 12.8 or so where they make peak power...but that all depends

Werd, don't go by your narrowbands, some say they have found a coorelation once the sensor is at a certain temp but I wouldn't trust much of their wot info as thats not what they were designed for http://www.hptuners.com/forum/showth...9805#post69805
