Can you rephrase the question? It doesn't really make sense...

sorry about that havent been to bed yet.

what i meant was is it necessary to remove the rear o2 sensor after the sim patch as been installed and the sensor is no longer in use? i have 2 antifoulers on the o2 sensor right now. i would like to leave the o2 sensor where it is so that i can repin the ECU and retune the rom back to stock if need be.

You could damage the sensor by turning it off but keeping it exposed to the exhaust gases. I believe mrfred said this happens rather quickly too. I am not sure how much less heat it will be exposed to by running two antifoulers though.

I have had a look at the patch, it seem to me it does more than needed (both heaters, front and rear) Was it intention or am I missing something?

Code:
00047E4A                 mov     #2, r4
00047E4C                 mov     #0, r5
00047E4E                 mov     #1, r6
.
.
.

00047E56                 mov     #1, r4
00047E58                 mov     #0, r5
00047E5A                 mov     #1, r6

They're both rear O2 related. One resets the high current code, and the other resets the low current/high voltage code.

Front O2 would be r4 = 0x200, 100, r5 = 0.

I setup a friend with this patch last night - he reported the cel was gone, I will get him to check the ready monitor to see if it completed.

I passed Massachusetts inspection today with this patch applied.

Previously, I had failed inspection with the Tephra v5.1, O2 Simulator on, and resistor mod with rear O2 removed. I believe the resistor was faulty because I was throwing P0037, which I am no longer throwing with this patch.

The only change was adding this heater sim code to the existing Tephra v5.1 ROM.

Also worth noting is that the O2 Readiness test failed in both cases (although I still passed inspection even though it reported "Not Ready"). This may be a deficiency in Tephra's O2 simulator, because the front O2 sensor is brand new. The FAA ECU Periphery is stock as well.

Thanks mrfred, Tephra, and others

If you had recently flashed it may have reported not ready rather than failed. Did you drive for an hour or so before heading to the emissions station?

Amazing you still passed, they wouldn't let that fly in IL.

I drove it for 2 days before heading to the inspection station.

mrfred, if I understand this right, there are four possible states for r5

0x0 - not ready as stated above,
0x1 - failed?
0xC - ?
0xD - ?

what about testing them which one is "PASSED"?

Combinations of r4 and r5 are used to indicate which OBD-II test is being reset. OBD-II code vs r4 and r5 are indicated in the OBD-II code table xml for Evo 9s. Take a look at the latest ECUFlash Evo 9 xmls.
