More Newbie help Please (STFT question/s)..............

[FreddyG]

Could someone Please tell me how to map my STFT's? I'vee done my LTFT's, but would like to know how to do my STFT's to average the two maps.

Also, is it odd that my two engine banks show the same values or is this pretty normal? I've read quite a bit about people having differences between the banks and just averaging them out.

Thanks in Advance!

Create a calculated PID for (STFT1 + SHFT2) / 2 in the file calc_pids.txt and then create a map where this PID is the data, and rows/cols are rpm and map.

Here's an example on how to create a calculated PID... http://forum.efilive.com/showthread.php?t=130

That's just fine that both banks are equal. :cheers:

Thanks again JoeCar! :cheers:

Would this be correct? If so, what do I do with it now, and if not, could you Please tell me what I did wrong?

STFT_Average2_pid.txt (http://home.comcast.net/~badassc5/STFT_Average2_pid.txt)

Thank You again!:cheers:

It seems to me that quotes (") are needed around the Expression and around the Descriptions.

Thanks joecar!

Where do I store the file then and do I use it then just like any other pid?

This VERY Basic Programming is new to me, and I feel like a kid going to pre-school as far as this tuning stuff goes.

Thank You for the help! I Sincerely Appreciate your patience! :cheers:

The calc_pids.txt file should be in the folder My Documents\EFILive\V7\User Configuration;

that file should already be in that folder, so just use notepad.exe to paste in the lines for your PID and save the file;

when you next start the Scan Tool it will pick up the PID from that file.

No worries, mate. :cheers:

Here's my calc_pids.txt as an example...

Thank You again! :cheers:

I think that I get it now! I just keep all of my pids saved to that file and the software refers back to that location. I'm just slow, but catching on a little at a time.
