I failed again, plus the guy tried to fail me for not having power steering on an OEM power steering equipped car. Luckily one of the other guys said hey miata don't come with power steering. Thats the only good thing that happen.
So here's the deal, I failed NOx low and high.
High NOx Standard 1179 mine 1310
Low NOx Standard 1304 mine 2082.
Everything else was great
High Speed 25 mph at 2276 RPM
HC PPM Standard (160) my reading (51) pass
CO% Standard (0.90 my) reading (.06) pass
CO2% my reading 14.4 no standard listed nor pass/fail
O2% my reading 0.51dard listed nor pass/fail
NOx ppm Standard (1179) my reading (1310)fail
Dilution% standard >6 my reading (14.5) no pass/fail
Low Speed 15 mph at 1936 RPM
HC PPM Standard (166) my reading (106) fail
CO% Standard (0.93 my) reading (.04) pass
CO2% my reading 13.9 no standard listed nor pass/fail
O2% my reading .9 no standard listed nor pass/fail
NOx ppm Standard (1304) my reading (2082) fail
Dilution% standard >6 my reading (13.9) no pass/fail
I'm not sure where to go from here, I know that this could be caused by the CAT- I replaced it last year, Water temp - but that seems fine per the Megatune, even when sitting at idle for a half hour. Timing - It confuses the **** out of me, and Matt from DIY said not to touch it unless I had a dyno\\
A new O2 sensor was suggested, but I don't think thats really relevant in this specific scenario. Since I'm running a wide band O2 that seems to be accurate.
Oh, and a lower temp thermostat.
It amazes me I was almost penalized for no power steering, but that fabricated harness, connected to the tundra coils weren't even noticed.
This is such a strange place.
