Oh ok, forgot you were running SD. Yeah the instructions aren't very helpful. I know there is some more info on: robertsnitrousservice.com. I don't remember if he was running SD or not. I remember seeing another link to a Camaro running a dry system on SD lemme try to find it.

Remember seeing this somewhere but forgot the link. I saved it in case i would ever need it: The IAT trick reduces spark advance and adds fuel during nitrous oxide injection. The LS1 ECM includes tables that modify spark advance and fuel enrichment in response to changes in intake air temperature. We take advantage of the fact that the range of these tables extends beyond normal operating temperatures so that parts of the tables are normally unused. You need to modify the IAT tables in these normally unused areas to reduce timing and add fuel as needed during nitrous injection. When nitrous is activated, a relay in the IAT sensor circuit, forces the ECM to read a false temperature that falls in the modified areas of the IAT tables. Normally, intake air temperature is measured by a thermistor in the mass airflow sensor (MAF). When nitrous oxide is activated, the timing-tricker relay switches a fixed 300 ohm resistor into the IAT circuit in place of the thermistor. This forces the ECM to read a temperature of approximately 85 degrees Centigrade. The modified table areas then take over.

I don't see why it wouldn't work with SD. You would still be able to run one tune with it too.

If you use the modifier table corey had posted up, it will work. It will take some logging to do, but it would work. Its a shame about the service issue.

Yeah, it'll work no doubt! I'm thinking i'll just adjust modifier until my plugs looks right. Thats friggin awesome

Do you not have a wideband?

Phantom

yes, why?

You were talking about pulling the plugs to check the coloring....I thought you was going complete old school!

Oh, yeah I will definitely not be relying on the wideband to tune my nitrous. I will be reading plugs
