spaz is right in this appl;iocation, where you are talking about a high impedance unit....they can often be difficult to drive to the low on times needed for a stable idle....especially in a V6

The interesting thing will be to see if a piggyback, ala e Manage, can control this units at a consisten rate over time. In many cars, piggbacks will work wekk in the short term, but if you log long term fuel trim, eventually the ecu gets wind of what is going on, and compensates.

I am surprised I don't see more datalog posts, especially from E manage users...it would really help hone in people's settings and their overall experience with the unit.
