I want to make sure when I go back next Saturday this won't happen again.

On Tuesday the 28th I flashed the 4.0.2 stage of MM's tune with my AccessPort and I've been driving around since then. 40 miles round trip to work and back.

I just got back from my dealer who said I passed everything but the emmisions because my computer was cleared. They said to drive it around for a few days and come back next Saturday and it should be fine.

Was the 4 days since I flashed the MM tune not enough time for an inspection to pass? If I uninstall my AP, I'm going to get a CEL for the secondary 02 sensor.

Any input?

 

don't uninstall your map... it'll reset the ecu again and you'll just have to wait that much longer. There are a couple registers the PA emissions computers check... cycles since last reset I think is the one that flags you bad.... although I don't know what value they're looking for.

Two weeks (with daily drive cycles) should be plenty of time to build up enough OBD data to pass without issue. I've passed emissions 4 times with my cobb map installed.

 

If you want to come out to Macungie, I could plug into it and see if you are ready for testing.

Exactly what I was hoping. Thanks!

That's a bit of a hike just to see, lol. Thanks though!

 

idle it for 10 minutes, drive slow with speed from 0-35 for 15 minutes, then cruise around hwy with 55 or so for another 15 minutes. shut the car off for 2-3 hours. that's usually 1 drive cycle.

then just repeat it couple of times. u should get it.

the computer just need to build trim and do some emission check (the pressure inside the tank for example)

 

idk where in pa you are but if you come up my way that wouldnt be a problem

 

At the dealer again. Theyre saying my "cat and O2 sensors are still not ready". RAGE

Im taking it to a mom and pop station...

 

hrm... let us know how it goes... I wonder if this is a Mazda diag or PA emissions computer thing
