I have just started roughing in the driving tune on my new setup, And i am having some problems with the wideband reading in tunerproRT. I am using saujp_v4 and an innovate lm1 wideband. I took output 2 from the wideband and fed it directly to pinA3 on my 730. I am getting a reading in the datalog but the numbers are off by approx 2 points. ie if the wideband is showing 15:1 in tunerpro it's showing 17:1 Is there something that needs to be configured in tunerproRt or in the LM-1 itself to bring these numbers in line?

 

I noticed in my datalog that the WB output numbers are mostly highlighted red but every once in awhile for like one sample it will turn black and the number at that point is inline with what it should be reading. Do I have to change the lm-1's output setup to use it with suap-v4? if so what do i change it too it's at the default value now. Also when setting the bin up do I just select the bit for the LC1?

 

I forget what the default values are setup on each WB.
The easiest thing to try is to set the RAW option in the bin and adjust the formula in the datalog to match whatever your WB is set to.
If its range is 7.35 to 22.3 AFR and 0-5 v output, use
X * 0.058980 + 7.350000 as the conversion.
See if that matches the other display (It should)
I'll try to find the list of the defaults I made a while back. Probably something I should add to the docs anyway.
Someone else may also chime in if you know what they were.
