Gen 4 Stock PCM Needed

[Rocket]

Thanks in advance for your help. Need to get serious so that I can pass emissions in AZ and also get my plates and insurance in order. Currently have a 2009 Convertible, Mopar PCM, intake, head work, headers, single high flow cat, and full 3" exhaust without the second set of cats. I do not have the stock PCM and will need to find out if the replacement PCM VIN will need to match my Viper VIN in order to pass emissions (assuming I can get everything else in order).

So here is my game plan:
1) Replace Mopar PCM with stock PCM
2) Add 2 O2 simulators - this is the link to the set-up I'm going to try. These simulators supposedly also address the heated O2 sensors.
Link for simulator: http://www.magnumtuning.com/en/detail/adjustable-oxygen-sensor-simulator/dodge/viper-srt-10
3) Put a couple hundred miles on Viper, check emissions status with OBD reader
4) Pass emissions
5) Put Mopar PCM back in. (Although I am tempted to tune the stock PCM to unleash the full potential of all of the work that has been done to the motor!!!)

Thanks!

Merry Christmas, Merry Hiss-Mass, and wishing everyone THE BEST in 2015!

Contact one of the supporting dealers and order an ECU. HP Tuner could also work wonders with all your mods

O2 sims seem to have issues on working with the gen4. If you go back to the stock controller and the O2's are in place you won't throw a code. I know that Late Apex "I think that's his name here" has the stock controller and bellanger setup. He passes TX emissions without any issues.

Also that's a pretty generic reference to a SRT10 with no year specifications. I don't think you will get the results you are looking for with this.

To add more color - my secondary O2 sensors are zip tied along side of the transmission - no bung hole to mount them in the current exhaust set-up.

(As most know, the Mopar PCM does not see the downstream sensors - and when attached to an OBD reader or the emissions computer - the system shows "Not Ready".)

[venomous08]

Even with a "sim" I highly doubt they will pass obd2 readiness, if I remember correctly.

You also don't even have to hook the O2's to the car with the MOPAR controller. Sounds like you will need to get bungs in place.

O2 simulators will NOT pass emissions, even with a "heater element". The programmers are a lot smarter than that, ha. These are not just comprehensive tests looking for items plugged in [while yes, they do look at that too], they are actual testing routines. The sensor output will change when the heater is activated and deactivated, and that is what the system looks for.

You need real O2 sensors installed into the pipe along with downstream O2 non-foulers to help along any sensitivity issues, and a stock PCM. Provided you don't flag any pre-heat codes on the upstream or airflow codes due to the headwork,, it should pass emissions just fine. If not, you will need some work via HPT to help sort out some of the CEL codes.

Your emissions test seem similar to mine here in Ontario Canada, I purchased the car last year in the US not knowing what might be required to pass an e test here. It was a little more tricky than I thought, but cost almost nothing in the end, just time. Car had mopar pcm and full belanger with 1 high flow cat, 02's were tapped and tied up underneath for some odd reason too. I swapped to stock pcm and built an extension harness out of the old sensors and then went and got new sensors to install. I thought I was done, but it still wouldn't set the rear 02 readiness code. I tried the spark plug non foulers as spacers didn't set code, tried 2, didn't set code..... I eventually drilled out one of the non foulers and took some catalyst material from a cat I had laying around and made tiny cats for each sensor. Only problem I had was that I could no longer fit the side panels back on. The e test place didn't care and it passed easily, set codes as ready within 10 minutes of driving, monitored that via torque app and a smart phone.

If you were not getting a CEL, but the catalyst monitor was next in line but remained Not Ready, it was likely due to the pre-test conditions not being met. It was likely just a coincidence that you were making changes which eventually passed- if the test had run, and failed, you would have had a CEL. The test was being delayed for some reason, and by coincidence did not run until your 3rd set of alterations.

If there's a $100 bill or two there's a way ;)I'm pretty positive that not everyone in the state of az is emissions complient yet have their cars on the road.. Btw this thread is over a year old :lol2:

Sorry I left out some minor details, it logged as "failed" and within a minute or two the CEL would be on. I'm assuming the high flow cats with quite a few miles on them were just not up to par for what the stock cpm wants to see. Luckily I only have to deal with that every other year.

Every other car I've had in this god forsaken province I've just built an "e test exhaust" and swapped in, did the test, come home and take it back off. So I guess come home and install side panels is actually easier.
