BLM- Long term fuel trim?

[rudder2fly]

Do you know how to make a log?

At the top of TunerPro, there are some buttons that look like regular buttons on a cassette player for example. Once TunerPro is connected to the ECM, you can then make a log. When you are ready to stop the log, press the stop button and a window will open up and you can select the name and where to save this file. It will be an xdl file.

You can name it whatever you want. Once you get that done, you can add it as an attachment here by selecting the "go advanced" option, then select the "manage attachments", then select the file and upload it.

As far as your problem with the alternator, I could not tell you what my opinion is about it, other than possibly a ground broken somewhere allowing regulator noise to affect the ECM, but this is merely a guess.

Well I hope the file is here! GS.
