You certainly need to pull some timing, I usually start with 2 degrees retard and try up to 4. Nitrous in most cases makes more power with a little less timing regardless of the knock threshold. Either way 2 is a good place to be if you don't have more options and time to test.

As far as figuring and getting the custom chip made... Is there any reliable way to translate afc correction factors over to the chip burner? Ideally one would have the chip burned after test runs (with a romulator) on the dyno, but I know this might not be possible. So is the fueling going to be a flip chip also (I don't even know if this is possible for you guys yet)? Otherwise you're no closer to getting it right that route.

As I said, if I missed something, please clarify.

there is a setting on the afc that i can change maps from say a nitrous map to an na map, so it wouldn't be running it all the time. But i don't see why i couldn't correlate the data from the afc to a chip later on for that nitrous shot that way i would only run the maps at the time i press the nitrous button. The moates 2timer will read half of the chip with na maps on it, but when its grounded it will read the other half of the chip with the nitrous maps on it, this will allow me to wire it to the nitrous switch.
