EBL log and combo tranny question....

I am running the EBL, and noticed my 1-2 shifts seem long. Looking at the logs, and the one attached is one of the better ones. Some take up to a full second for the 1-2 shift. The 2-3 shift is much quicker. Is this a sampling rate thing, or does it appear that my tranny might be slipping some. Also on take off it seems to show the same thing. The shift does seem long on the track, almost like it is spinning, but it is not. It is a turbo 400, behind a mild 454.

The rich dip on launch is almost gone now, although this pic doesnt show it. I added some timing and its much better.

Wasn't for sure where to post this, but I figured more here would be familiar with the EBL pics, and might have more to compare it to.

Thanks,


(if a mod could move this to the tranmission board, that would be great.)

As your transmission is not computer controlled, it probably indicates the start of internal problems. You might want to post this on the Transmission Board and see what they say.
