When I first start up and drive while in Open Loop it will go Rich while I am on the gas and come back when I back off of it. After into Closed Loop, I can give it some gas and it doesn't really go rich at all. I have adjusted the AE/TPS % and AE/MAP #'s too. With my laptop hooked up, I press on the gas a bit and see it is in AE for just a very short time, but when in C.L. it goes a bit lean.
When reading the XDF it says that the AE/TPS% is only active for a 10th of a second or so then the AE/MAP takes over for the next 2 seconds or so. When in the AE/MAP should the computer still show in AE?
With that being the case, do I just need to keep adding to those tables? If so, what problems am I going to have when it's in O.L.? I haven't check the pressure under load at the TBI yet but assume it's going to drop a little. Should the fuel pressure drop at all when the gas is increased? That is a bunch of questions again, but I very much appreciate your guys's help.

Thanks,
Rick
The fuel pressure looks good when under load.

What about the rest of my questions?

Thanks,
