Also when I finally got my recirculation setup done it went away completely. Also what are you clamping the MAF and MAP voltages at? And what is the before Inector size set at? I'm not sure how the AEM F/IC is setup for the injector size perameters but when GReddy did their base map they had the before IJ size at 325cc and this is incorrect. it caused some starting and warm idle fluctuations. We changed it to 310cc and the idle and starting problems went away. I think you are having IAT temp problems causing that quick lean conditions. Good luck bro....

Those are all interesting things to note. They are also things that take a lot of time to determine if they are even causing trouble. The FIC does injector size not as a complete number (like injector flow rates) but rather like an Apexi AFC where you have to reduce the pulsewidth with a percentage based on maf or map.
As for the clamping, we are using the strategy started by Shawn Church in the tune, which uses maf all the way without clamping a specific voltage in the table... that's one of the strategies used with the other maf setups that I think would also work really well. But we're sticking with what Shawn Church started.
