x_hawker is an unknown quantity at this point
The 06 has a rev-up motor which yes, is still a de, but with different cams and variable exhaust cam timing compared to the 03-04 which did not have that function. The reason I asked is because the 06 ecu needs the sensors to allow for variable exhaust timing and when it doesn't get a signal it throws a CEL (my 03-04 motor doesn't have the sensors for, hence the CEL).

So my question is, 2003/2004 ecu in a 2006 model - will the smog system have an issue with that even though they are all technically vq35de's?
