i have a 92 integra with a 2000b18c1 swap with a p72obd1. dc header, intake, and exhaust are my only mods. new o2 sensor was put in this month, new spark plugs and wires and a new distributor.

CO -
limit - 1.10
test - 5.92

HC
limit - 275
test - 423

NO
limit - 3600
test 595

RPM
1724

dilution
18.6%

 

Testing high on HC and CO, but low on NOx means that you're probably running too rich, and not all of the air/fuel is being ignited by your ignition. Here's a nifty little chart: http://www.car-sound.com/04charts.asp

 

yeah my narrowband's sayin it's running a bar rich but those things aren't that accurate...

thanks for the chart...what would i do about the air injection?

 

Make sure your air filter is clean, and then maybe advance your timing a degree or 2, but make sure it's within the factory spec of 16° +/- 2°.

 

replace thermostat..?

 

ok here's what i've seen:
this is a 92 b18b...almost the same thing


and mine


as u can see..the breather filter is where the hose on the 92 b18 is and it goes back into the intake. that could be it?

 

do you have a JDM B18c1?

 

there arent any c1's in japan, only c's

there are no numbers in japan

 

usdm b18c1
