JDM H22A
Swapped into a 96 EK Civic
P26 S300 v1.6 or something.
OBD2 to OBD 1 Jumper Harness
DC Sports header
Spec D Exhaust
Test Pipe
AEM Short Ram Intake

I started with a base map and changed injector size and fuel trim.

Running way rich 17.1
IAT is always high?
Why does my 02 sensor report 3.1 volts narrowband

On second note:

Ordered PLX wideband so I can get the car tuned. Does anyone here know of a good tuner. New to the Upstate South Carolina.
Which o2 sensor plug should be wired into for the narrowband/PLX in near future? All white with red stripe or all white. other three wires are common.
If i was hooked up to the wrong one would that be why i have to disable o2 sensor heater?

17:1 ir lean and not rich. Lower numbers are richer and higher numbers are leaner.

Car is running very rich. I think my o2 is bad. Got a PLX ordered today and found a local shop to tune it. Thanks for the help.

Any reason why l. voltage is 3 volts?

Not sure what this input is used for before hooking a wideband to it.

It is also strange that this voltage mimics my AF as it scales across the graph.

Made a new datalog with the wideband installed. How do I get my AF to match my Wideband guage output. I followed the PLX install to D10. I followed the directions from hondata. but how do i know off by about 2.45

Have you followed these instructions?

Have you adjusted the voltage offset to get them to match?
