    I'm also interested in this Min/Max Override feature, so I can do away with injector scaling. How do you use it, and how do I know if the memory of my P12 controller will support it?

    Could be "Burst Knock Retard" which buffers the spark advance when you step on the gas; or if your Charge Air temperature gets too high it'll also pull some spark.

    Looks like in my case "Cranking VE" is another one not to mess with, even though the document says to. My car was hard starting until I changed it back.

    I think this is one table you don't change since it is delta g/cyl, as I found out. I did it the same as the other spark tables and the car ran that crap on starts.

    MAF Scaling Question?

    When doing MAF Scaling wouldn't you also scale the Spark tables as well, since the spark tables are based on CAM and now the calculated CAM is scaled down; i.e. instead of say 1.15gcyc it's now at...

    Yep, it was running on the rich side from the 60# injectors. It's on the money now except down near idle which is still running about 4% rich.

    I think I figured it out for my LC1, based on HPTuners values they use for an LC1; basically a custum PID for EIO1 V/2.443+0, would give me an output of 1 at gas 14.7. If I'm not mistaken.

    Well that all makes sense, so because my LC1 is configured for gas it converts lambda 1 to 14.7 AFR, so if I were to configure it for E85 then it would read about an AFR of 9 at lambda.

    I noticed this while in open-loop, but in closed-loop it looks like it is trying to do lambda for gas still. I'll have to do some more testing I think.
