Ah, where to begin? This has not been a good day. Started off doing a cruise to get more data on why the car is running so rich. While driving the car it began rich as usual, it went very lean as you can see in the log. During the run I was adjusting parameters 5 and 6. I'm guessing only parameter 5 was in effect since there was no boost. The first change was to 121 and then 114. Ran okay atfirst and then went lean. I had to pull over and shut down and put parameters 5 and 6 back to 128. The second log is another cruise at no boost and everything is very rich. CF is pulling the max out. The third log is from tonight where I was just at idle and adjusted the AFR at low RPM and KPA to 13.0 to try and get the idle to steady out (it oscillates around 900 RPM+/- 50). It never really gets to a good steady idle. The final log is another attempt at adjusting parameters 5 and 6, unfortunately as you can see the chip didn't seem to work as CF never came on. It read 128 on the scanmaster and the PLC the whole ride. I pulled over and restarted the car and restarted the PLC. It still didn't work. Here is where it gets interesting, when I pulled in the garage and turned off the headlights the chip started working. Turned the lights back on and it stopped. I've never had an electrical issue before and the car ran perfectly fine with the extender chip and Gen II before the swap. So now I'm looking for suggestions. Thanks.
