C16 in fuel cell=WAY rich.
C16 in fuel cell=WAY rich. Hey guys,
I finished up the stand alone fuel system and put C16 in the cell. I went out and did a test run, logged it w/ my F.A.S.T ecu and it's WAY richer now w/ the C16 in there. Right now I spraying 100hp (52 n20 jet, 31 fuel jet) and the air/fuel ratio gets down to 10.2:1 where it use to be at 11.6:1 on 93 octance.
What do you guys think? Should I go down in fuel pressure (currently at 45psi) or put in smaller fuel jets.

To keep things consistent, I think you'd be better off swapping jets than raising or lowering fuel pressure. Always try to keep that constant as you tune.

Would have to agree on ajusting the fuel pressure. Changing the fuel jet can (not always) change the A/F more than you might want to. Adjusting fuel pressure gives you smaller incremental changes.

Verdad Gallardo I probably don't. I just need something to support 700rwhp/900rwtq.
A couple of guys at NX recondmended C16 and I figured I could run a tad more timing and/or a little leaner and make more power.
