That is the whole point of this patch. It is going to simulate the rear o2 heater signal, therefore the ECU will think that there is still a sensor attached. You will have to run an o2 simulator, like the one found in the v5.10 Tephra roms, or Mrfred's separate o2 sim.

Correct, it doesn't call it above 2k rpm. No point in wasting ECU cycles on something like OBD-II diagnostics when going WOT.

Sorry for taking so long to get this posted. A *stock* patched 88590015 ROM and the accompanying xml definitions are in the link below. Add the definitions to your ECUFlash 88590015 definition file, open your current ROM, and then copy the table values from the stock patched ROM to your current ROM. Flash to your ECU and no more rear O2 heater CEL.
tephra, do you want me to email you a copy of the source code?
