logging LTRIM readings - OBD-2 software Can anyone provide detailed instructions on how to log LRTIM data on OBD-2 diagnostic software?
Which paramerers are important?
How is this information logged in OBD-2?
Is it necessary to cut and paste the data to MS Excel to average the data?
Thanks...

These are the OBD-2 software parameters that were used by a friend to check the air/fuel/timing curves. As I recall, he belived the readings should be slightly negative.
I'm not sure why software companies such as OBD-2, LS1Edit and others do not provide explainations to helpo users understand their products.

You will also want to log the enhanced FTC, and FTL PID's and not include the datapoints in your average's that have the FTL as 'disabled'.
For timing, you will want the following:
SPARDADV - Generic
KR - enhanced

You need to have the most recent version of the software and of the enhanced LS1 F-body bin file, which you can download from his site. If so, let me know and I'll email you the files.
I would be interested in the favorites you have constructed for Car Code OBD-2. I use it occasionally just for kicks.

Yes I am using the Alex Peper version of OBD-2. I downloaded the latest version of this software two weeks ago.
What is an LS1 F-body bin file?
Is it possible to send these files to me; I need instructions on how to use them, however?

Thanks..

I'll send 'em to your email address. To use them, go to "Favourites" on the menu bar (Alex must be a Brit) and select Open to browse to the appropriate file. Then, you're good to go.
Have fun.
