need Evo 9 owner to test rear O2 *heater* sim patch
Kracka and I tried this on his car today; it works! He's spending QT with is girl right now but just wanted to relay the message: he had a big smile on his face when we ran the car w/ the old resistor crap unplugged

Unless I'm mistaken, This patch by itself will not allow that because it only simulates the heater circuit, however in tephra's V5.10, there is an O2 sensor that simulates the signal, so together they will allow you to unplug.

That's correct. I also have a standalone patch to simulate the rear O2 sensor signal for the 88590015, or a tephra ROM can be used. tephra mentioned somewhere that he is holding out on releasing v6 for this patch.
I believe my IX has that rom. So could I use both patches to completely eliminate the rear o2? Maybe I not understanding this patch but why would you need just the heater? My antifouler works just fine.Excuse me for my lack of understanding.

except not using the hardware (resistor mod) in conjunction with the newer patch posted in the first post and no rear o2 all togather with all readiness tests 100% a-okay.

well removing the rear o2 sensor completely from the car be necessary when one has the 2 antifoulers installed with the sensor? resaon i ask is so just in case i need to bring it in for warranty work i can return it easily to stock
