DPfix help passing emissions

psmitty95 · 04-06-2014, 05:12 PM

Hi guys so I installed my DPfix the other day and have not been able to get it to work. I'm almost positive it is installed correctly as I have double checked everything. Problem is I am getting an SES light for P0141 and P0142, O2 sensor heater circuit bank 1 sensor 2, bank 2 sensor 2 . Please let me know if you have any ideas what the issue is. Pics are below

My car had the same problem right away, dont know why because my 135 did not. I had the same DPs on my 135. I made no adjustments to the DP fix and the errors finally stopped popping up after about one month.

Hmm odd... I guess i'll keep waiting and driving and hope they go away then. Did you pass emissions after?

How many miles did you drive since putting it on?

Probably 50 ish

JETBLK335i · 04-06-2014, 08:00 PM

I drove around 80 miles and then i had readiness. Might kick in then or you need to adjust the dial.

Did you get a SES light at all though? Maybe i'll just keep driving in that case

Yep, but all we have here in Illinois is the OBD readiness. No smog test. Error free to this day.

Yea all we have here is OBD readiness too. Last question... Did you keep clearing the codes or just drove with the SES and it went away one day?

I kept clearing them.

I have not yet got a emissions (I live in Illinois also)....so it is just readiness via the OBD port?

Yep, very simple.

Sweet, so install dp fix, put jb4 in map 0...load my stock bin file (have wedge flash)...drive 80 miles and go get tested?

bimmertt · 04-06-2014, 09:59 PM

Install looks right from the pics. I just went through emissions myself with the dpfix and never had any codes/issues. I left the car on COBB's stg 1+fmic and drove the car ~60 miles in total. I did do a last ditch drive cycle because I saw the EVAP was not ready and my emissions deadline was coming up.

Yep, just be certain you aren't throwing any codes prior to going.

Do you have INPA? You can verify rediness with that, and prevent potentially wasting the cost of a test.

Don't know that you need to remove the flash (I did not remove my fuel flash). Just the other 2 things you mentioned. Re-flash may trigger need for resetting readiness. I use a $20 scanner that checks readiness before I go. This year replaced the battery which meant the drive cycle was needed to set all the readiness flags. http://www.amazon.com/gp/product/B00...?ie=UTF8&psc=1

took me 4 or 5 drive cycles / adjustments before I obtained readiness. Pain in the balls. Literally on my drive home from testing my car threw a code and SES light. Huge pain in the balls, good luck

That's just what I wanted to hear, almost worth it to put dps on...I have that job down to a hr lol!

N54 TuNeR · 04-07-2014, 11:21 AM

I'm using the BB Flash.so would I have to flash back to stock bin?Or can I leave flash on but set Jb4 to map 0 only?flashing back to stock would mean doing it all over.

Thanks for the info i guess i just have to wait.

On my phone so cant multi quote but for everyone else would a backend flash effect it? I have my flash still loaded. Also, how do i verify on inpa? I was using a generic obd reader but inpa might be easier
