Went to get a vavle adjustment this weekend and dicided to retune my VAFC2 just for the fun of it.

B16B motor with stock internals
Mugen head gasket
Mugen intake
Mugen EK9 twinloop catback
Feel's 4-2-1
Denso iridium plugs
NGK power cable

3000km since the last oil change.
Stock ignition timing
35c weather

Can someone explain to me on the dyno sheet upper right hand corner what is "CF:SAE Smoothing:3" ?

 

I think it has something to do with smooting out the hp/tq curves to make them more uniform and easy to read.

 

Good numbers

 

That A/F curve looks really good. I would have tried to lower that 6k to 7k curve. But you made pretty good numbers.

 

Not bad, you're running a little lean in my book, for street/ daily-driving. I like to see 11.5:1 for daily driving. Civic's might be different though.

11.5:1 is a little on the rich side for a n/a motor.

 

Is going over 13 but below 14 in the 6k-7k range for A/F dangerous?

My swap does the same time from 6k-7k and I have a chipped ecu.
