I'm sure you could get the standard forum discount.

Well I don't know. I'm thinking it should be better than the forum discount.

let me recap
I ran a Tillman tune for about a year
After I got headers and high flow cats I started running AM tunes maybe 6 or 7 years now
I always told them I needed to pass emissions.
I never could pass emissions
I contacted them several times to try and get this fixed over a period of years.
They did not help
I finally said screw AM and tried Steeda tune
I blew a cat related code pretty quickly because Steeda does not turn off O2 senors. Steeda's tune actually found an existing problem...IMO
So a little more investigation with AM and they finally tell me they turn the rear O2's off.
Well how in the hell can I pass emissions with the rear O2's off
I believe AM uber rich tune gummed up my cats.

So nice to use someones tune and tell them you need to pass emissions but they never tell you they turn off the rear O2's until its to late.... Basically I have been transferring the title of the car into another family members name. This give me another year until I have to be tested again.

That was one of my reasons for switching from AM/BAMA to Brenspeed.. As I only had to tell them just one time that I needed the rear 02 sensors left turned on for emission purposes.. Needless to say my car has passed emissions every time with no issues whatsoever !

Glenn

Well they are nice to have on so you know if your car is running to rich or to lean

m05fastbackGT

I couldn't agree more

Glenn

I wonder if anyone has passed emissions with the rear O2's off.

m05fastbackGT

I highly doubt that, as the OBDII test will more than likely kick out a not catalyst ready code

Glenn

Yea I know the rear O2's have to be on to pass for sure. That is why I always thought they were on. I did tell them I needed to pass.

m05fastbackGT

So did they up turning them on ? If not, give them one more opportunity to make it right and if they still don't.. Then I highly recommend making the switch to Brenspeed..

Glenn

I was thinking about asking for a good cleaner for my cats as a joke but really?

Glenn

I ordered a gallon of that stuff.

Glenn

Once the 02 sensors are turned on I blow the codes. Is it possible that my cats are not efficient enough in the first place?

m05fastbackGT

If you didn't pop up any codes when you were still running the factory cats, then it's very possible.. Also check your rear 02 sensors to make sure they're still functioning properly..
