In reference to something like the COBB Tuning Accessport, which allows changing ECU maps...
My question is how this would relate to CC classing, or if it's legal at all. The last paragraph of Appendix D reads: "Any engine management or mechanical changes, such as the ability to reflash or remap the engine management setup at the track that would produce increased engine performance beyond that declared in the declared average power shall be prohibited."
It's not clear to me whether this is a blanket prohibition on things like the Accessport, or if it basically means, "leave the Accessport at home."
One thing that leads me to believe that it's legal is the wording earlier in Appendix D which reads, "If the car has adjustable engine management it must be noted and described on the Dynamometer Certification form."
We're clearly operating on the honor system with respect to dyno numbers, and that somebody actually dynoed their car in competition configuration.
For instance, with my car, the Accessport offers "off-the-shelf" maps that would bump my car by about 16 peak horsepower, translating into 23 CC points. But would it be legal?
Finally, for the purposes of Appendix D, which treats "2WD Stick Shift" differently than "AWD or automatic", is a PDK considered an automatic?
