I spent the better part of this morning messing with my car. mapped a new maf scaling file with my split second software and got to do a couple hard pulls. It's on the rich side in general right now, but that's good!

The 5 liter is running well and it makes proper boost etc.

I cannot get it to idle smoothly! It idles like there is a vacuum leak, but there doesn't seem to be one.

Ideas?

Map sensor going south? or is the ecu fully adapted after the reset? ecu need sometime to re-learn the throttle position (my 43 needs about 10miles to fully learn the throttle). I dunno but maybe you need bigger injector or fuel pump with 5.0!

I wonder if you're seeing the same issue as Saaboteur.

Here are a number of threads I have found that are about a rough idle:

Hope these help. If you do it get it figured out make sure you post the solution so others can learn

I do not have stock fuel pump/fuel lines etc.

I have done some further maf tuning and reset the computer once and the problem seems to have largely gone away. I do still have slightly imperfect idle, but nothing like it was.

If it gets worse again I'll swap the full the TB over from the other motor in my garage (don't know why I hadn't thought of that yet).

thanks for those threads too!
