COBB AP CEL masked, force readiness for inspection

This right here. Is there anyway we can wire in resistors to fool the ecu into thinking it has the air pump plugged? Im getting my Cobb AP within the next week and I'll be masking emissions to pass NY state inspection and I also wanna ditch the air pump. But from my understanding of reading thru this thread it still won't clear readiness unless the air pump is physically plugged in? Even if I mask the DTC's with the AP?

Driving my unreliable rx8
There is at least one or 2 people that report it working with a mazdamaniac tune. In the same thread i posted that teamrx8 reposted a list of codes mm used. Thats what I'm running right now and hope it works if not ill start trying to fool
It.
It.

every year, same story.... plug in air pump... drive for a couple days to week with it.... go do inspection.
Here's what I know: In most areas 2 tests can fail. With the air pump disconnected I do not believe the test is even able to run so it stays in a pending state.
At least with it connected it'll eventually fail or pass -- mine normally fails because it runs a couple milliseconds more than it should -- at least that's what the readiness test reports.
In any event, the test eventually fails or passes with the air pump connected. So long as no other tests are failing you'll still pass the OBD2 inspection test.
If the readiness test is actually reading the O2 level of the forward O2 sensor during the cold start cycle then it doesn't matter if the fan is merely connected, the test will fail without the fan blowing into the manifold.
Has anyone simply tried jumping the pins and leaving them jumped? Continuity seems like a much more likely form of measurement than resistance or load.

Thats what i was proposing, use a resistor to jump the 2 connectors.
A lean voltage when the fan is on could also be faked with a relay and a few resistors. So it gets a lean voltage when the pump is on. Then when the pump goes off it relays back to the o2 sensor output.

The monitor looks at more than just pump activity Shell, It will not become active if the following
Open circuit connecting pump
Pump start up within 5ms of starting the car
Rich to lean condition detected
Which is why I just left it in, especially with the headache of my new exhaust no way am I swamping manifolds every year for this so I just leave it in and running.

for 2001+ vehicles the EPA allows 1 test to not be set i.e. pending. There is no pass/fail requirement for the one test. Pending is fine. I have personally witnessed/been involved with RX8s not having an air pump and reaching the 1 test pending phase and passing the state OBD2 test using the Cobb system.

6/8 is no bueno.

Thanks guys this is what I was looking for. I believe NY state allows you to pass with one readiness monitor not setting.
I saw the list earlier in the thread of all blocked emission codes MM blocks in his tunes, so long as I block everything else and all my readiness monitors set I will mask the air pump DTC and delete it completely and whether it sets readiness or not I believe I can still pass as long as all my other monitors ready.

Bumping this back up. I have a problem with my readiness monitor setting for the air pump/secondary air.
I created a map specifically to pass inspection (I have all CELs blocked on ATR). Been driving for probably about a month with them all blocked and Secondary air just doesnt seem to ready itself.
I have the air pump deleted and the solenoid is deleted and blocked off as well. Any one have a solution to this beside plugging the air pump back in.
I no longer have a stock air pump.
