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? |
Run in 2nd gear?

heres my normal msq. The only change was I pulled 10 out of the timing table, over every cell.
