I need someone smarter than me to verify my work.

If you change the 9.72 to 10.0 and the 0.038666 to 0.039216 then the calculated AEM AFR matches the AEM documentation.

I don't know where all of these parameters need to be changed with MS so that everything will work. I am a damn MS newb and don't understand how all of the INI's and such work, but I am trying.

Help me help others with AEM widebands with mismatching readings!

Thanks.

I could probably come up with a custom number to E85 too if anyone is interested.

 

After looking at this more this morning I don't think this is going to cure my car. When I run the orginal numbers my gauge should read higher than the laptop, but it doesn't it is the opposite. These new numbers look like they should only make it worse.

Does anyone have a unit on a stim that could verify any of this stuff?

I did notice that the target AFR also uses these numbers in its calculation. I'm not sure how that effects things.

Also just realized that my numbers that I came up with match the Innovative 0-5 linear. Perhaps I should just try swapping settings in the setup and see how that works.

 

Mine is still off by around 1 point. I tried changing the values to what are listed in the paper that came with my gauge but no change.

 

You have a wideband INC file then? Mine seems to be inside the msns_extra INC. I am on a PNP though.

 

Yeah, this is with a wideband file.

 

I have to investigate. My wideband is acting up after auto-xing today and it seems to be stuck around 15.5-15.7 most of the time. Sometimes it changes and tries to work. I guess the interior get's ripped out tomorrow and we'll see what is going on.

 

Ok stuck guage was a connector coming loose to the wideband. See my other post in the PNP section to see how not to install your AEM wideband.

All problems are now fixed via my other post. I'd double check all your wiring and do it right.

 

I tried this and couldn't get it to work either. I'm using a DIY MSPNP and I changed it in both files; ie the one listed in the first post, and the one under my project file for 9495 w/o maf and no luck? I'm using Vista and just saved the file elsewhere, then moved it to the right folder so I could save changes.

 

It works! I adjusted the config file under my project and perfecto.....though now it can't find the table for afr for ve3.....but I'm not using it so i don't see it hurting anything.

 

This work on TS?

 

Yes, megatune and TS use the same .ini file

 

It took me awhile but I finally got it, thanks a ton for this info guys

 

I downloaded megatune just now from diyautotune and won't let me use tunerstudio anymore, I guess it overwrote it and says I need beta. So now Megatune works okay except it won't let me edit anything. I get as far as megatune 2.25 but there is no MTcfg to be found.

 

notepad won't let me make changes, it keeps saying access denied. I have full admin rights and even tried opening the programs as an admin fffuuuu

 

anyone have a solution?

 

OLD THREAD I know but i cant seem to fix my issue i've read over this several times and cant figure it out.
I upgraded to the HI-Res 11d firmware loaded my old tune into the ecu after i flashed the ecu. only issue i'm having is that the AFR TARGET TABLE is reading values 0-5 whereas my old tune worked off of the values of 10.00-20.00
I changed the settings values as stated in post #1 and still the AFR TABLE values have not changed.
What am I doing wrong

I FOUND MY PROBLEM THIS POST CAN BE DISREGARDED.
