After a long stent away from dsmlink over to AEM i'm back to ECMlink! This is the first idle log after getting everything setup and although I feel like i have an okay understanding of things, it's great to get some more experienced eyes on this. Quick pertinent mod list:

2.0l
E85
950cc FIC (have staged injectors, but only the primaries are wired up currently)
Speed Density
GM IAT
AEM 5 Bar
AEM WB Gauge(Simulated nbo2 on front o2)
NGK AFX(rear o2)
s90 TB
fp4r cams


Besides a terrible initial cold start, once it gets started and warmed up it seems to run okay. Fuel trims appear to be close, airflowperrev is pretty high though. It seems that idle RPM still wonders marginally.

Thanks in advance for any insight.

Alright, so maybe I'm putting the cart before the horse here and need to get idle dialed in better, but I went for a quick cruise around the block and am getting something weird going on. It is cycling between closed loop and open loop when it shouldn't be. Whenever it flips it goes super lean and falls on it's face, like I hit the brakes. I'm not sure what is causing this, hopefully something simple. Initial thought was cylinder misfire, but that DTC is unchecked. Looks like even in closed loop it is wanting to constantly add fuel.

Here is a quick clip of log. What am I missing?

Thanks!
