some data i got from my obd2 to usb

[bova80]

Ok so, I got this OBD2 to usb adapter yesterday and was just testing it out and wanted to see if i could see data from my o2 sensors. now i think the eq_rat11 is the equivalent ratio for lambda so that is what i graphed also along with rpm. now i could be wrong about all this but i figured someone should know. also i would like to add that i was looking at my IAT (intake air temps) and with my cold air intake i was seeing temps slightly higher than ambient. all this data logging is new to me so i couldn't figure out in excel how to get 2 graphs to overlay while having axis labels on both left and right side so i have them above each other and marked where i was in 4th gear. i didn't go all the way to redline but i was just messing around, so if someone could decipher this or tell me this isn't the right data, i would appreciate it.

just did a new log on the highway in 4th, the logging for 4th starts at about the 15 tick mark and goes to about the 25 tick mark where i stopped logging. then i started a new log in 4th and it goes to the end. enjoy.

did another run as well, this time started in 3rd, sat in 4th for a bit til i had some open space, then went to 5thand let off.

It looks like you are off to a good start.

The lambda reading will normally max out at 2 so it is correct.

so can you tell me what the o2 sensor is saying? like what is rich and what is lean? do i just multiply by 14.7?
