Car is a 2009 335i FBO..... with catless downpipes

do i need anything to pass its first emissions test or can i just set up an appointment and hope for the best.

do i keep it flashed with the MHD 94 octane map or flash back to stock?


any insight would be appreciated



thanks

I think the emission test now doesn't really check the "emission gas" anymore.
I remember when I was with my e46, they just plug in the code checker and check if I have any error codes and that's it.

[Msport335]

if its true that we are allowed 1 "incomplete" on the test then i should be okay taking it in as is since my MHD only reads the catalyst as being "incomplete"

[armansiu]

i am not sure. my mechanic said it needs to pass all tests. one of my O2 sensors failed, so need to replace before test. don't flame me if i am wrong. lol

You will definitely need to fix the O2 sensor. Do you have access to any code readers (Torque app + BT OBD dongle)?

[marcvtec]

you will need the bms down pipe fix to be installed.
O2 sensors "must not be the one fault code"

when I did mine few weeks ago all I did was flash back to stock and drove the car about 40km never went over 3k rpm cats showed ready only evap was off still passed and I don't have my primary cats didn't use dp fix either

This is the only thing that doesn't "pass" for me the last two times I've had it tested - always reads "not ready", I guess because it's not warmed up or I haven't driven it long enough pre-test. But if that's the only problem, should be no problem passing.

passed yesterday. flashed MHD to stage 0 and installed wedge dp fix. Evap was the only thing not ready but still passed.:thump:

time to turn it back up again

[rick100]

you are allow to have 1 in the no ready state out of the 8 parameters

the information is online

[marcvtec]

my statement was wrong,
any one code is allowed.

I have a 2009 335i with catless dp with the MHD tune and this is the readout from the MHD app:

There's 1 incomplete and 4 "not avails" which I'm assuming is because they aren't valid for the car. Would this pass emissions?

As long as you only have 1 incomplete (Not Ready) and no codes that light up the Check Engine Light, you will pass.

correct, the "not available" means those tests are not valid for the car.

Great! Thank you for your response.

I did mine 2 weeks ago with MHD installed. I had stock exhaust at the time but because MHD was installed it showed cats not ready. Still passed.

Reporting back. Did my emissions test with downpipes and MHD tune and passed without a dp fix. Yay!

May I ask where did you go to get your emissions done? Thinking of getting catless dp myself but I have an emission due soon. I usually go to oil changers in mississauga, and from what I'm aware of they just plug in their reader and no visual inspection.

Also, what kind of dp do you have and where did you buy it? Still undecided. lol

Thanks!

I just went to Canadian Tire for the test. I have the BMS down pipes and MHD tune. Bought the down pipes from Mike@N54tuning.com.

If I was you I'd wait for 2 reasons:

1) Emissions due soon, might as well be safe and get the easy pass then install catless down pipes.
2) Black Friday is almost here and most vendors on here have sales on these parts.

In the same boat here. Running a dp fix with stock tune. Will the dp fix show "ready" on the test?
