emissions tuning
we do a 2 stage dyno emission test. The gearing and stock tire size kills me. It makes the engine lug having to run in 3rd gear.
Anyway
My HC and CO are too high.
25/25 test
HC 210 Allowed 174
CO 4.67 allowed 1.12
50/15 test
HC 233 allowed 180
CO 5.48 allowed 1.01
what's the best way to pull these down? I already pulled 10* of timing out per the inspector.
Drop req fuel?
flat line the AFT target at 15:1?
drop the fuel table by X?
