Hi ...
I have civic ES K24A1 swap...
and I wont tune my car but I have problem with primer O2 sensor its read too hay
I don't no is that something I can fix with tune or something mistake in harness ??
I read a lot and tried anther PO2 from DENSO /
* The original one /
DENSO 234-9005
192400-8040
10N24
* The new one /
DENSO
192400-8040
11N10
but its also read hay !! I bot quick run video if you want to see the AEM a/f gauge

the car mode /
stock k24a1 swap
stock harness ( RCX-S 2004 ) & jumper from hyper racing
heeders 4-2-1
Skunk2 intac & throttle body
2.5 custom exust
hondata k pro ( PRB )
Note : i use the K24-accord calibrations
PO2 read over 30 !!

Re: PO2 read over 30 !!
Does it give cell warning on your ecu?
What are the voltages on the primary O2 sensor?

Re: PO2 read over 30 !!
First, what is your fuel pressure!? It looks like at one point you are in closed loop and the STFT is +46%
Second, You need to fix your 0* fuel map.
Third, Holy mother of what looks like knock. Your creating around 3v from your knock sensor...
Verify that you have proper fuel pressure. Also verify these A/F with a separate A/F gauge that is standalone.

the voltages on the primary was measured with multimeter in series withNazul wrote:Does it give cell warning on your ecu?

A6 and A16 = 0.1 mV(with ignition on and fully warm up)
the car had p1166 for heater circuit malifunction and p1298(eld circuit high voltage)
the relay was on "always on" with the a/f heater wired to 87a
swapping this wire over to 87 we removed the p1166
eld was disabled and now car no longer have cel
car no longer has knock now here is the log
but still high a/f is the only problem now
can you suggest better way to diagnose the problem?
checked all the wiring all have continuity
a/f wires to ecu:
1(white) to A6
2(blue) to A16
3 + 4 to A1+A22(both black for heater circuit)
all confirmed with multimeter

Re: PO2 read over 30 !!
You have a daughterboard communication error. You need to resolve the low battery voltage issue when cranking. Do this before you go any further.
Re: PO2 read over 30 !!
this is before
after swapping relay to constantly off(87 to a/f heater, instead of 87a to a/f heater) the error now no longer appears
both the p1166 and daughter board error has been eliminated
eld disabled
car no longer has cel
