As far as I have seen, it definitely runs a point to two higher. Obviously idle and cruise are stilll at stoich, but under load, it is definitely higher.

What I am referring to is the fact that the JB3 and Procede run quite a bit leaner than we are used to. Is that because of limits from the fuel system, or is that because the greater atomization of the DI motors allow a safe but leaner A/F ratio.

I think my post was worded poorly, sorry for the confusion. I was trying to say that Innovate, AEM, etc. use Bosch sensors with great success and accuracy. Some FJO units (particularly older units) use the NTK sensors.

Also, there is nothing wrong with Bosch sensors, they are great actually, it is the CONTROLLER that usually leads to inaccurate readings like the PLX units.

Makes more sense now. LOL! The FJO is showing to be VERY responsive in the data it retrieves!
