Emissions

[RSBAD454]

Due to the fact I live in the nazi state of California, are the canned tunes emissions compliant?

[Mike_Levy]

You'll be fine. Technically they aren't CARB approved yet, but they won't know the tune is even there unless you tell them.

Just read some stuff about new smog laws coming into effect this year. Smog technicians being able to check cal ids etc. as part of test.

Clean Scanning• The communication protocol that the vehicle uses.  This includes SAE J1850, ISO 9141-2, ISO 14230-4 (Key Word Protocol 2000), and ISO 15765-4 (CAN Protocol).  Some of these protocols permit the use of options that effectively create distinct sub-protocols. • The readiness profile of the vehicle.  This provides information on which of the 11 readiness indicators are “supported” by the vehicle.  The indicator profile is most often affected by whether or not the vehicle is equipped with secondary air or exhaust gas recirculation. • Module ID’s and addresses.  Vehicle computer networks typically connect multiple computer modules together, including the engine control module, the transmission control module, and often times other modules.  The manufacturer assigns an ID or address for each of these modules.  There is no required convention for how these module ID’s are assigned, so they typically vary between manufacturers and even between models within a manufacturer’s product line. • Parameter Identification Count (PID count).  This value can be calculated by the inspection equipment from information reported by the on-board computer and indicates how many parameters are available for downloading through the vehicle’s data stream.  The value varies for different vehicle makes and models.   The data parameters identified above can be compared to known values for each vehicle being inspected.  The comparison can take place while the vehicle is being 8 inspected so that discrepancies can be immediately addressed, or it can take place during post-inspection processing of the data.  For the latter, discrepancies could trigger enforcement investigations against specific inspection stations or inspectors.  Most states performing OBD inspections already collect this data and are successfully using it to identify fraudulent tests and take action against the inspectors and/or stations without the need to do further undercover observations or evidence gathering. Newer vehicles include additional sources of information, which can go as far as positively confirming whether or not the downloaded data is from the vehicle purportedly being inspected. • Calibration ID (Cal ID), a number assigned by the manufacturer to identify the software calibration of the vehicle.  This ID is usually unique to a particular vehicle model. • Calibration Verification Number (CVD).  This value is computed based on contents of the on-board computer’s software.  It is typically unique to a specific CAL ID for a particular vehicle model, or even at the sub-model level. • Vehicle Identification Number (VIN).  Newer model year vehicles store the VIN electronically in the on-board computer.  This value uniquely identifies the test vehicle, and can be compared to the VIN on the registration renewal form.

None of that is changed in the canned tunes. All the parameters will be READY, the VIN and CalID don't change. Even on the dyno/sniffer tests some states do, the tune has no effect of emissions.

[RSBAD454]

Ok, just thought I'd ask before I pulled the trigger for a Trinity.

yeah, our tunes will pass a plug in or sniffer test, despite the fact that they are not 'legal for sale in CA'....they'll pass there as well. Funny, if they dont know its there, it will pass, but god forbid you tell them you tuned it, they wont even see if it passes

[RSBAD454]

Yes, the laws and rules are quite silly.

[06MonteSS]

here in CT they do the OBD plug-in test... have never removed my tune before getting my emissions testing done, have always passed no problem...

[Mike_Levy]

They do that in NY too. They used to do the dyno and sniffer in the city, but that ended in the early 2000's.

question I am currently running a cel and have emissions test coming up. I have the 93 tune on a stage 2 pcm. If I clear the codes and take it for testing right after will it read not ready and fail me or does you tune force it to read ready? because last emissions test I cleared the codes right before driving up and I passed it I am just wondering if this was a fluke?

[Mike_Levy]

It should show as Not Ready.
