This is definitely not my realm of expertise, so I will make sure that Bill sees this thread when he returns from Utah.
Just FYI... we had a customer send his
FICM to us to be reprogrammed. Immediately upon re-installing the
FICM, the truck ran worse! As it turns out, it had nothing to do with the
FICM itself (I believe it was an injector issue); it's just that with a different
FICM calibration, the problem became apparent. I can't remember which customer it was, but he posted about the situation on
www.powerstroke.org. I'll search and see if I can find that thread.
Edit: Found it!
