Datalog target afr

Hi,
Does anyone know if there is an easy way of datalogging target afr. I'd really like to see it in MegaLogViewer just below the real afr...
Cheers
Dave

Dave,
Add the line:
Code: Select all
entry = afrtgt1, "AFRtrgt1", float, "%.2f"
to the [datalog] section at the end of the INI file (megasquirt-II.ini, for example). You'll see quite a few others there, add the line above anywhere you like (where you put it determines where it is shown in the datalog and viewer listing).
This may give you values that are 100 times to large (ex, 1370 instead of 13.7) - if so, find a line in the same file like:
Code: Select all
afr1 = scalar, S16, 28, "AFR", 10.00, 0.0
and change it to:
Code: Select all
afr1 = scalar, S16, 28, "AFR", 0.100, 0.0
There are corresponding entries for afr2 and afrtgt2 if you are running dual wide-band sensors, and you can add that too.

brilliant, thanks Lance. It worked perfectly. I then set the field min & max for both afr & afrtrgt1 in Megalogviewer to 9 & 25 and they overlay perfectly.
I think this really could have been solved by me
though, sorry!
Cheers

Dave,
No problem, I'm glad you brought it up, it reminds me to add it to the default INI files for V2.6 and V2.8 MS-II code!

Holger,
You probably didn't modify the ini file that Megasquirt is using. If oyu look for the audit.log file (makes sure it is dated the same as the last time you openend MegaTune) you'l see all the files and directories MegaTune used to open. Look for lines like:
Code: Select all
r MegaSquirt-II.ini
+ C:/Program Files/MegaSquirt/MS2_v2.8/mtCfg/MegaSquirt-II.ini
MegaSquirt-II.ini:0102 #if LAMBDA, including=false
...
The first line tells you which ini file was used (it will be something like megasquirt.ini, megasquirt-II.ini, or MSnS.ini). The second of these lines tells you which directory it is in. That will be the file you want to modify.
