Here is what I mean:

 

Anyone knows if these values can be correlated?

 

I completed the patch and so far so good. I have a USDM car so I figured it would be no problem.

 

I installed permantly my LC-1 yesterday using analog output 1 to simulate O2 sensor #2 with your trigger points but in less than 100km I get a P0421... maybe different voltage points?

 

Looks pretty eash, thanks a lot

 

So is there anyway for us to force the ecu to complete the readiness test at all times?

 

Hi Moro
yeah maybe - what you could do is to try to change the lower point (try 13.65 or 13.6) and see what happen .
It should work as on my IX I have it since 10.000 kms without CEL with the lower point setted to 13.7 (I also tried 13.8 but I got the CEL in less than 100 kms)

At the end , think also to have a look to your low & mid fuel trim to check that they are within +- 10%

 

Trims are ok, < 0.5% low and 1.3% mid. I will try to set lower switch point to 13.6, but voltage set to default are ok? I mean 1.1V for values < 13.6 and 0.1V for values > 14.7.

 

yes I have always use the default voltages . i'm only changing the switch points

btw do you know is there any way to disable the rear O2 sensor on an IX EDM model (88840016) - I see that you have access to more parameter in ECUFLASH that I currently have - any info/links appreciated

 

Nope, at the moment if you change periphery0 zeroing the second O2 bit you will get heater disabled but keep throwing P0125 (or any code you like like thepra teach ).

I started to disassembly the 88840016, but holidays has gone...

 

Thanks - yeah same for me - no more holidays - but its winter so less time spent to drive the EVO = more time for tunning ECU , chassis , ...

At least I can remove the resistor for the heater . Can you confirm that the following XML are correct for 88840016 :
<table name="ECU_PEREPHERY" category="Misc" address="faa" type="1D" level="4" scaling="Hex16"/>
<table name="ECU_PEREPHERY1" category="Misc" address="fba" type="1D" level="4" scaling="Hex16"/>
<table name="ECU_PEREPHERY2" category="Misc" address="fca" type="1D" level="4" scaling="Hex16"/>
<table name="ECU_PEREPHERY3" category="Misc" address="fda" type="1D" level="4" scaling="Hex16"/>
<table name="ECU_PEREPHERY4" category="Misc" address="fea" type="1D" level="4" scaling="Hex16"/>

and which bit is for the second 02 sensor ?

Cheers

 

Yes, the XML entries are correct. The second O2 sensor is (or should be ) the second one.

I have not tried yet with LC-1 on second O2 *AND* periphery0 bit disabled, maybe no P0125 and no heater...

 

You guys are great, thanks.

 

Instead of dealing with resistors, could you just leave the o2 sensor installed and do the fix for the ECU? OR just leave it winded up under the passenger seat? That way you won't get a o2 sensor warm up alarm.

 

Yes, you could keep the sensor to make ECU happy in heating, but not under the seat! It becomes very hot.

On the other hand if you have a WB in place of the sensor it is more confortable to wire a resistor, IMHO.
