I see a stable PW and duty cycle... the VE value stays the same as well. I do not see a reason for the AFR to suddenly go lean.

do you have a seperate fan controller? is the temp on it set to 170*? you want an EFI engine to run around 200*

did you disconnect the factory O2 sensors?

I figured it out, at least im about 99% sure i did and i feel like a idiot.

Amazing how you can over think something. Lesson learned, check the basics!

Did you see anything way out of line in with the tune? I have not yet used the auto tune function.

Got it running again and it did ok for a bit, it did start surging. I did two data logs. Iv never looked at a datalog of someone's to know what is considered
"normal". The first log is where i first started the car and it seemed ok IMO. The second log i just hit the "start log" button when it started to act up.
Not sure what is going on with the TPS as it looks as if i was opening it by hitting the throttle but i wasnt?

Before it started to surge it seemed to be idling fine even though the log makes it look "to me" like everything is jumping all over.
