It has been HOT the last few days and this has messed with my AFRs. I'm running the 2Bar OS on my 2012 Corvette, stock engine with vortech supercharger. I have two plots with different IAT's, and I picked an RPM to compare. I have some quick data of the compare below. The air related stuff seems to have about an 8-9% drop in it. Which is about what I would expect given the 30*F air temp change. But the Cylinder mass and the wideband readings have a 25% swing. It seems the cylinder mass is used to calculate the injector pulse that is giving me the bad AFR. How is the cylinder mass calculated? I'm sure there is a table I could adjust to compensate for this, but I would have thought that these temps would have been within what the stock settings could handle. A large swing like that doesn't make sense to me, is there something I'm missing? Any advice, insight, or guidance would be helpful.
Here are the interesting things I noticed between the two different runs, cold vs hot.
