Both errors relate to the rear O2 sensor, probably disconnected? is it a standard rom or a Tephra version?

cat not up to temp CEL .you can turn it off in perifery bits "141 not in FSM" or something.

I get them (or use to) with a high flow cat and less timing retard when it gets colder.

Have you enabled the rear O2 simulator in the mod options, this should remove the P0136 error, not sure about the P0141 (heater circuit error).

i have ecu+ and I am simulating the rear o2 senor, however the p0141 code pops up. because the o2 sensor was completely removed by the previous owner.

Does the heater circuit make any real difference to the way the functions so long as the signal is still being processed?

This patch will remove heater circuit cel. With 88840016 you will still have problem with rear O2 signal as there is no simulator like in 8858 tephra rom. With tephra v7 rom and if your rear O2 is totally removed: enable simulator from tephra options, change this bit to zero and cel is gone

88840016:

Code:

<table name="Heater CEL" category="Rear O2" address="2ee1f" type="2D" level="2" scaling="blobbits">
        <table name="Bit values" type="Static Y Axis" flipy="true" elements="8">
            <data>N/A</data>
            <data>N/A</data>
            <data>N/A</data>
            <data>N/A</data>
            <data>Rear O2 Heater CEL Enable(1)/Disable(0)</data>
            <data>N/A</data>
            <data>N/A</data>
            <data>N/A</data>
        </table>
    </table>

ALright so I have to get someone to do this, who would be a wise choice to have it done?

As for the simulator my ECU+ is already simulating the signal just not the heater circuit

Is there anyone I can send my ecu to in order to have this stuff done? I don't have an openport or tactrix cable.

I guess it would be more efficient to buy the cable (worth-while investment in any way), get the sufficient .xml for your ROM from knowledgeable people here and apply the change yourself (such things are really easy).

Other option is to find someone around you with cable and ask for help - this operation really takes about 3mins (download your ROM to laptop, press "-" once and upload ROM to the ECU) if .xml is available (5mins if you need to amend it

) and shouldn't be a problem at all for anyone who knows at least the basics of Ecuflash tuning.

I have added this routine to the definition file 88840016.
Pushed the ROM file back to the ECU. (ECUflash has reported identical image afterwards).

Is there anything more to do?
