o2 extenters

[polskifacet]

I searched around and there is almost no info for o2 extenders / anti-fowlers for the SHO for us that live in states that check "ready" status. Does anyone have this info size, install, anything to take the guess work out?

They are out there...they dont work due to the new logic for determining cat efficiency

 

[polskifacet]

What other option is there? Changing dps to stock for emissions doesn't make sense or PPE are the only ones that work.

Yep...easiest thing is to buy catted pipes that others have had luck with...be careful because there is a difference between simply not getting a CEL and being able to set readiness monitors.

It can be done in the tune but most people in buisiness wont write a tune to facilitate that....and id venture to say they dont even know how...its not obvious in the tune what to change and the SHO uses different logic than even the coyote copperhead ecu and gt500...most tuners wouldnt spend time trying to figure it out

Anybody with ppe able to check readiness monitors for us?

Actually it does if you think about it.

If you live in an emissions required area and you dont own tuning software you will regret owning catless pipes

Works fine on PPE carted DPs after the O2sensors are heated up... About 2 min or less on a cold start.

What are you talking about?...when you flash or reset kam maybe only the fuel system or component monitor and maybe misfire takes 2 minutes...the cat, 02 and evap and egr will take much longer

And once they are set you dont need to start the car to check.they remain set

I have logs but dont have access to them at the moment,but it took roughly 11-12 miles for I/M readiness with the PPE catted DP from EPP. Mike B  :thumb: :thumb:  Z

For all of them?...i thought 1 of them had a cold soak timer so i didnt even think one drive cycle was possible to set all of them...in addition to fuel level requirements and intake air temps...i have a ford vcm II and it tells you the drive cycles and shows when each monitor completes

Iirc on the Torque home page you can click test results and then you can see mode 6 and mode 9 data which shows all of your monitors.

Also, if you watch lambda and AFR at cruise you will see the car alternate back and forth from lean to rich for about 10 seconds then return to stoich. I'm pretty sure that is one of the readiness tests being performed.

It is....its performing the cat test...its called the integrated fuel air method for determining cat efficiency...fomo its in the form manual emission stuff...it pumps a small amount of fuel in to see how much the cat takes care of...its checks it against how much the rear 02 changes....basically, if it takes a lot of fuel to make the rear 02 change then the cat is really efficient....if it only takes a little fuel then the cat is shot
