Hi all,

I had the fortunate opportunity to install a ProCharger kit on a new 2014 Corvette Stingray. Having experience working on all model Corvettes, I am happy to say the C7 is by far the easiest model to work with yet. Everything is simple yet sophisticated, it was a very straightforward process. I have attached both the stock tune file and ProCharger's tune file for anyone who is interested in dissecting the E92 controller/tune. I have some questions based on what I am seeing in comparing the files:

2014 Stingray Stock.ctz
2014 Stingray ProCharger Tune.ctz

1.) It appears as if the VVE tables have remained unchanged and the supercharger option has not been selected. What is this engine controller looking at to determine it's fueling?

2.) The MAF table was scaled back, a lot... Wouldn't the added air being forced into the engine mean the MAF should be scaled higher?

3.) The AFR was leaned out to 12.7, being forced induction, isn't this too lean? Maybe the direct injection system calls for a leaner AFR.

4.) What exactly is "commanded power mode, A, B, and C"?


That's all, feel free to discuss!

Thanks
