You might try PM'ing Abubsmary (sp?).. He might be able to provide you with the answer to your question.
Everything sounds pretty good to me so far. I'll go ahead an clean up the post I was working on and get that up in a minute. As for the NGC, I'm not sure if he was at one of the tech sessions or has other first-hand knowledge, but I don't think it's that there are
no tables in the computer and code. It's more likely the computer doesn't just do only direct table look-up and comparison of cells like older systems, but uses tables in conjunction with "smart" algorithms to determine fuel and ignition events.
I've read some papers on predictive modeling and powertrain controller design and that's a more like scenario. Who knows though besides the people who program it until it gets cracked. More than likely when that does happen you'll be able to adjust the way it works, but it's not going to be as simple as only tables getting changed like a lot of other/older cars. The actual equations and tables will both have to be modified together to get everything to work right.
