I have a NO plate that I have been spraying a 200 shot with jetted at 78N/42F and I am still just a tad rich with 11.3 afrs and plug reading. Tonight I am going to use my new Nano 4500psi kit. Should I go back to a 46 fuel pill?

What pills are you guys running with Nano?

 

41 @ 55 psi on the stand alone. AFR averaged around 12.2, iirc.

 

Fuel jetting didn't change at all for me with the nano. When I tried a .078N, I had to go down to about a .033N and it's still not right from looking at the plugs and wideband (11.2-11.5 n/f). Standalone is set at 58-60 psi. Remember, retarding timing affects a/f also.

 

running stock jetting for HSW plate. I suspect my FP on my standalone is a little higher than expected. Its all relative.

 

If you do the Nano conversion from the jet you are running right now then it would call for a 46 on the fuel side. I would put the 46 in for the first initial hit and then back it down from there depending on what the plugs are showing.
