Both of those only read from Bank 2 correct?
I was playing with the O2 sensor data today, and I also was getting strange readings in the area of 11-76. Curious if Bank 1 - Sensor 2 is the correct input for O2, and how to interpret the reading.

thats why the accessport is so nice. I select the maps that are adjusted for the proper trims, so the car doesn't have to find out how much fuel to add/remove since it's closely matched to what the car wants.
I don't have the cat, but I have all the oem sensors in place.
I made a video back in 2006 of the Palm OS running the CanScan - If you look at 0:35 sec into the footage, you'll see I can select cat temp and it graphs the numbers on the palm:

well... OEM sensors - cat = EGT??? lol
would be super if anyone who understands the dirty secrets of the CANscan could help us out with how to poll the CAN for the rest of this data.....
i have a headache right now, but it seems i was thinking a few days ago that there should be a lot more possibly interesting things on the CAN

I used the CANxx short term fuel trim bank 1 and long term fuel trim bank 1. I didn't connect the AP to verify the numbers are the same, but they looked about right to me.

i am just going to put in my first couple of xgauges today... but i am just as interested as everyone else about the oxygen sensor readings...
apparently the display reads a value 0-99. i have not looked at it closely, but based on the attached PDF that was posted earlier.... shouldnt we be able to adjust the MTH(math) to scale what is displayed into a meaningful number???
i think it would maybe be important to have someone log AFR's(Cobb AP/EMU/O2 sensor) while also reading the scangauge display; to plot a set of data
if someone could catch me up on any specifics of what values are actually being transmitted across CAN... i can prolly hook up with Kane and compare scangauge readings to known AFR's......

I have seen values anywhere from 20 to 80, and sometimes it will actually sit at 50 like a good little stoich mixture.. But yeah I have no clue how to actually interpret the reading..

I have the gauge setup and I've had it for a little while now. Unfortunately we can't use the MTH function to scale the 0-99 reading to a usable value since the output of the WBO2 sensor is non linear, so there's no way to scale it properly with addition, multiplication and division alone ![Wink](https://www.rx8club.com/images/smilies/wink.gif)

Wow that's a nice interface, and a pretty good refresh rate.. Sometimes I wish the scangauge was a little quicker. If we could find out how to get the cat temp that would be sweet too! Save me from getting an EGT gauge...

ah, i didnt even think about the non-linear thing... well... it would still be nice to have an idea what 0-99 values equate to in AFR or lambda....

on a positive note... the HP gauge is whack like mysql said... yesterday at full load at 7000rpm i saw 291HP !!
lol
also LT/STFT work it seems... STFT isfloating around -2/-3 LTFT around 6/7... only got a couple miles to look at it though

watching the fuel trims to try and become familiar with how they change in correlation to driving style/conditions
watching water temps for obvious reasons, and because i disconnected that damn low coolant light switch
watching the O2 sensor trying to make heads or tails of it... this is what i see so far
decelration/injector cut-off conditions - values all the way down to 0 consistently
hard acceleration - values ranging from 50-upper 80's
cruising - values typically around 75-85
MYSQL - i wonder if someone* who is familiar with the PCM/CAN would be able to assist us with the reference points to poll the CAN for that Cat temp sensor???
***Hymee? i dont know of anyone else off the top o' the head

hey be careful about that coolant, I hope you're checking the level frequently - if the level gets too low the temp sensor won't be accurate (doesnt' it have to be submerged to work...?)

also, i'm going to japan for a couple weeks, when i get back i am going to look seriously into the Cat temp sensor as well as some other things..... someone here was kind enough to enlighten me on what direction to proceed with retreiving other various data that is on the CAN

I'll snap his neck.
My 4 are generally intake air temp, water temp, MPG, and engine load. I was hoping the codes to do AT fluid temperature would come out, but I don't think it will. At least not until after I have a gauge installed ![Smilie](https://www.rx8club.com/images/smilies/smile.gif)
My HP readings are actually not too far off. They explained to me in an email that the scangauge shows you gross HP, not brake HP. Gross HP is the figure before you subtract driving accesories, etc. He said that ghp is typically 25 percent higher than brake horsepower (bhp is the rating the manufacturer gives). So if you take 75 percent of your 291 hp reading, you actually get a reasonable number.
That said, I have heard of some people seeing really unrealistic HP numbers. But mine have always been in the realm of possibility.

i do not even know if that data is floating around in our CAN, but if it is, i may find it. Of course, you or other will have to test my findings, as i dont know anyone with an AT.

i'm pretty sure that HP rating is just a guesstimate from the fuel rate (ganged) & rpm's.
i'm surprised I actually felt the need to say that, it should be obivous since the scangauge only considers so many parameters (that the can bus makes available).
