1st time tuning NOS
1st time tuning NOS Hi
i'm finishing my NOS install
92mm plate setup
Standalone cell
NOS launcher controller
I have jets 50-100-150-200
Setup>
C5 vette MN6 3.42gears
Ls2 404ci 11.4CP TFS215cc FAST92mm Kooks 1"7/8 ans so on
I use HPT for logging and tuning , my only motor setup has the AFR set to 12.8 and Spark is 25-27 degree SAVE threw the rpm band, but it's not knocking in 29-30 degree but it's not gaining much above 28
so i was gona start whith 100 shots on pump gas 93 and work my way up, maby gona but some blend of race gas into the cell to be extra save but tune it for pump only
questions is?
1. The AFR NA is right will i need to fine tune it on the spray or are the jets doing that work.
2. AFR on Nos where will i wante to see that mid 11´s or ??
3. Timing: Where should i have my timing set at??
( i´ve read to take 2°off each 50shots so 4° should do it but it´s better to take more off first like 5-6°right and work my way up)
4. i´ve also read to pull the plugs after nos runs to see the colour, is that nessecery if i´m logging the car for both AFR and Knock??
5. Plugs: i have both NGK 7 irridium and NGK 8 too should i use the 7´s for the 100 shots or go straight to 8´s
6. plugs2: should i have them stock gapped or what ?
thanks

2. A good safe spot for the nitrous systems airfuel will be 11.8
3. At the power levels you are at the 2 degrees per 50 hp will be a good rule of thumb.
4. Pulling and reading plugs is the most accurate way to tune. However many people at the power level you are looking at do not pull plugs. They set the airfuel at 11.8 and remove the timing. If you need help learning to read plugs look at carters threads and then start your own and we will walk you through it.
5. I would use the NGK BR7EF plugs for up to 150 hp. B8EFS plugs would be good for the 200 shot.
6. Gap them at 35 degrees.
