AEM UEGO Wideband and TS

[gomach1]

I picked up an AEM 35-8460 wideband a while back to save for a project. Is it compatible with tunerstudio? I don't see my particular model in the list...
I'd rather not have to buy another one but if that's what it takes I'd rather know now.

Thanks in advanced

Do you have any information about the calibration curve on this one?

I don't have any information unfortunately....I'm thinking its an older wideband.

I have two of those....try the below
You only need a few points although I listed all. I will check mine in TS when I get home and make sure this is the set.

An easy way to calibrate is to have a "Voltage Guage" on your TS. Make your A/F on your Meter 10:1 and read the voltage in the software. Repeat for 13:1 and 17:1.

Enter these three break points into your TS. I had to do this for my guage also until I found the Instructions in a box. I am not 100% sure the ones above are correct, but I had them written down. The 4100 guage is the same internal controller so try the 4100 AEM in the siftware.

Awesome thanks for the info!

This site is great!

Hello,

So were do i go to enter the data points listed above? so far this is what Ive tried but been unsuccessful.

Documnets > TunerStudioMS projects > Myproject> ProjectCfg > Main controller > (project comes up in word pad?)

Go to page = 7 ( Target AFR table 1 Bins for VE table 1 (find sensor used))

is this were i enter the data points?
This is what they look like now. what should they look like when i change them??

#elif AEM_LINEAR
afrBins1 = array, U08, 0, [8x8], "AFR", { 0.03867 * displayTargetAfr/14.7 }, 251.0, { 9.72 * displayTargetAfr/14.7 }, { 19.57 * displayTargetAfr/14.7 }, 2

Are you using an MS1?

If you have the WB with the above output, you can select: "Innovate LC1, MTX-L, PLX 0-5V 10-20:1 AFR"
That is the above linear calibration 0-5V 10:1 - 20:1

Thanks for your reply and taking time to help me with my situation
Am i using MS1?
- yes

Ive been using tech edge linear 0-5v 9-19:1 for the whole 6 months i have owned the car, not sure why it has worked, but it was always dead on with tuner studio's gauge.

recently i changed to rx-8 injectors. a member on another forum suggested i change my voltage correction for .10 to .20. the car ran bad and i changed it back.
up to that point is when i remember noticing that it read different.
ive tried all of the settings that correlate to 0-5v wideband. and they are all reading from .5-1.0 afr OFF all of the time.

I just tried the innovative lc-1 0-5v option AND it was .5 afr off. it was the closest.
looks like my gauge in tuner studio that reads O2 voltage is never hitting higher than 4.76v
how can i compensate for this

So I take it TS is reading about .5 AFR lower?
Make sure your WB is grounded with the MS.

[deathtrapmiata]

Ok. I dont think that is doable or maybe it is already done. I thought there is a metal flange that is beside the throtle body on my miata were it is usually grounded. I went out and checked there are a few different cables grounded there.
I did buy the car with the controller installed so sorry im hard to find things
Still getting a max of 4.8v and the highest afr im seeing is 18 and then i get a "---" on my gauge

[deathtrapmiata]

So can i not modify the "code" in the project config file? i understand that these data points need to be entered but im just not getting were in the document... anybody know what page and where?

[LT401Vette]

For MS1 you can add a custom AFR calibration by editing the mainController.ini, but it is unfortunately somewhat cumbersome. (hence it was simplified for MS2 & MS3)

so do you think the MS is seeing 0-4.8 V for 10:1 - 20:1?

You have me thinking... There are new features in TunerStudio that would let me put a custom linear calibration option in the ini file so you could provide 2 voltage/AFR points and it would calculate the AFR from that similar to MS2 and MS3. I will update an ini to support that.

what do you mean? are you sending me a file?

[LT401Vette]

Yes I will post a file with the updates.

I will be traveling this week, that sounds like a good job for the airplane.

Wow thanks man! thats so nice of you.

now were can i find it? or will you just post it in this thread when its ready?

The ini with a Custom Linear Setting is attached.
However, it works best with version 2.5.19+, so I bundled the new ini with the 2.5.19 beta update.

If you use it with an older version it will work but changes to the calibrations won't take effect real-time for your AFR tables. It will be fine for the afr gauge and data log, but you won't see the calibration effect to the AFR table until your reload the project.

If you install the beta, to change to the new ini:
- Open your MS1 project in TunerStudio
- Open Project Properties (Press CTRL+P)
- On the Configuration Tab, Click "Show Advanced / Offline Setup"
- In the ECU Definition Drop down, select "MS1/Extra format 029y3*********"
-------> Important: This will already be selected, it will be the last selection in the drop down. You don't want the last one. Look up the list for the same selection that is NOT at the bottom. The Bottom selection is always simply the ini file that is currently used by your project. The listings above that are from the TS libraries.
- Click Ok.


Now your project should be on the new ini.

To use the new "Custom Linear Wideband" option:
- Open your MS1 project in TunerStudio
- Open Project Properties (Press CTRL+P)
- On the Settings Tab, Under EGO Sensor Selection, selection "Custom Linear Wideband"
- Click Ok, the project will reload.

Now you will have a new Menu Selection under Tools called: "Calibrate AFR"
In this dialog you can set the voltage and AFR for any 2 points and all other points will be linearly interpolated as they are for the custom linear option that is written to the MS2 & MS3 lookup tables.

I saved the file to desktop and in the setup/cfg drop down i chose the saved file. Now i have a calibrate AFR option in my tools just like for the MS2&3 users.
This is awsome!

Will i have to calibrate this every time i tune or open up TS for changing stuff?

Man this is so awsome. THANK YOU!

EDIT. UPDATE.

went back through and followed the instructions.
i think i was running ver. 2.5.05
so i did it like you were saying...
opened up the attachment as " open in tunerstudio.exe"
got a warning message and then it asked me to update to a new version, and then said i had to choose a wideband, went through and chose the first 02y93 firmware? not the last one? and then went to properties and chose the custom linear wideband, and then i have the two point calibration tool.(which is so awsome)

is this right? DUDE thanks so much

~~ zack

If you get the Calibrate AFR under the Tools Menu, you are on the right ini.

Ive been using this for a while. and i have some questions for you phil.

1. i notice that if i change the calibration at all then my AFR target tables will raise or lower by a few tenths of a point.
does this tool simply just change my afr table to compensate for what it would be? (so i shouldent modify the afr table after calibration?)
or when it changes my targets should i go and re-set them?
could this change what my actual AEM gauge is saying? (not the one in tuner studio, the one i have in the cab)

maybe i am doing something wrong, some insight please sir.
