FTC Numbers

[white2000ta]

Guys,

I just finished my LS2 402 engine swap. During the process i installed a 2004r transmission. The tranny has a speedo ring, and a wire for the lockup converter and thats it. I havent worked out the speedo, its all over the place!

My real question is how does the PCM know what FTC to use? I think that becuase of the tranny we may not be hitting the right tables. Does anyone have any experience with this? Is there a Fuel Trim Cell chart I can refer to? I have EFILive logging FTC information. :nixweiss: Below is the link to the log file. We are still working on getting the idle trims down.

Thanks for the help

You can set up your own boundries to make any fuel trim cell table you want.

Do a search in the navigation window for "trim boundry" and it will pop up.

Reviving this post - how are the trim cells determined, what combination of inputs controls them?

PCM must be in CL, and then it looks up B3809 and B3810.
