High HCs at idle
I failed the two speed idle test here in texas because my hydrocarbons are too high at idle.
Can I realistically get these lower at idle without a cat? See my sig for car setup. Since I have the ability to tune via the translator Gen2 i'd like to try that before adding a cat since that requires much less welding  Results from test: High speed RPM 2471 HC(PPM) 85 PASS CO(%) .89 PASS CO2 (%) 13.7 O2 (%) 1.0 NOx(ppm) 0.00 Dilution (%) 14.6 Low Speed RPM 0929 HC(PPM) 585 FAIL CO(%) 1.08 PASS CO2 (%) 13.2 O2 (%) 1.7 NOx(ppm) 0.00 Dilution (%) 14.3

Gonna be tough. Without a cat, and no EGR functionality. You've got everything working against you.
