Just did a hot rod etest, Results as follows …

HC ppm 318 61

CO % 2.52 .04

NO ppm 3353 4390

RPM 2751

at idle …

      limit       reading

HC ppm 300 71

CO % 1.50 .01

RPM 756
Dilution 11.01

Stock SR20, apexi fc, 10 psi, magnaflow high flow cat, 94 octane, runs wicked, no boost leaks or anything.

I m thinking maybe a new o2 sensor and run the test on stock ecu and i should pass? Etest guy was saying it looks like its running lean at speed. And it didn’t smell to good either. Not like that rotten egg smell without a cat, but like pollution smell.

Anyone know what i can do to make this thing pass?

give her a good hot run before you go in and add some sure pass to your gas

High NOX means your engines combustion temp is to high,are your spark plug electrodes white?
Use a stock pcm and a really good 3 way cat
Check anything to do with the engine running hotter than usual as well.
Good luck man

Pour a shit load of methyl hydrate into your gas tank and it will pass.
