error P0141 and P0136
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

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

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.

first ECUFlash write to ECU

Pushed the ROM file back to the ECU. (ECUflash has reported identical image afterwards).
Is there anything more to do?
