I can confirm here is that I am using this ARAP WB to datalog. I have been testing out some things with this bin for Ivan, and I can tell you IT WORKS!!

Now this is for use with a linear output WB, such as the LM1 or LC1, not the DIY WB. I have the LM1, and I today I logged a normal run into work today, about 20 minute drive. It is great to see the actual AFR in time synch with all the other parameters. As stated above, the MAT data field is stuck at -40 degF. Not really a big deal for MAF cars, since that only controls the EGR on/off, not used in fueling for MAF. And the engine run time counter is not correct. Now I just need to go and make some WOT runs, and see what I get.
Hey Ivan, maybe you could have used the MAP field for code, instead of the MAT field, since we don't even have a "MAP" sensor in a "MAF" car!!
This is great stuff!
