what is required when adding FI to pass emissions test?

[Jaymar]

I myself don't see an issue with a tune, just so long as it doesn't shut off the rear O2 sensors. It's my impression that in one of the strictest states for emissions testing, CA where I live. When they read your OBD II port, all they are looking for is that all of the required monitors are reading "Ready". Beyond that, there is the visual and if you have a E.O sticker for that aftermarket equipment, you won't get dinged.

I highly doubt that the emissions testing facilities, has the equipment that has the capabilities to read the code and know that it's not stock. I don't think that even a dealer service dept has that capability.

I don't know why our ECUs can't have multiple maps, that can be changed on the fly. I came from the Ecoboost platform and there, you can have multiple maps loaded and all you have to do, is press the up and down arrows for the cruise control, with the cruise control off. Press a button, the tach needle will move to the 1,000rpm, 2,000 rpm, 3,000 rpm, etc. 1,000rpm = map 1, 2,000rpm = map 2, etc. IIRC, you can have around 5 maps in the ECU at one time, simple. No need to get your handheld device and reflash to another tune, unless you are adding another map.

Coyote doesn't have the same map support EcoBoost does, completely different control strategy for the ECU. And the means to check for a factory tune via checksum most certainly exist but as far as I know are not currently used by smog check. Most that I know about are checking IM readiness which gets them very close and still accommodates CARB approved mods.

Too bad there’s no way to reload those type of tunes when it’s time for inspection and then just run a custom tune the rest of the year

Why not? that’s exactly what I do.

Yep, once EGR is green and Fuel stays red, I can pass here in Texas. Fuel takes a while depending on what fuel level you're at.

you’ve actually passed like that not assuming?
Far as I know you can only have one monitor not ready and none turned off in states that check

Just got inspected yesterday with this so yes. EGR was green, FUEL was not ready. It can vary at the state level I believe. Only the major populated counties have emissions testing in Texas. Everywhere else does not.

In California they plug into the OBD port checking readiness monitors,check engine light, and any codes, vin number, check for any modification to the ecu. If it is modified have to have the E.O number and they checked with the EPA make sure that the e.o number matches that car And what all it coveres. So a smog legal supercharger on 15 through 17 mustang will not be legal on a 2011 2012. I worked at smog shops for a long time

Just ran into this in Austin, TX today. I have a Stage 1 Whipple with the Whipple tune (no other performance mods), but had 3 sensors "not ready", so it failed. I have not driven the car enough according to the shop, so I'm heading to Temple to watch my son's baseball game, then doing a test-n-tune at Little River Dragway afterward . Hopefully, that will be enough for the sensors to "wake up" and be ready for a re-test (~150 miles all told).

Sometimes it takes more than a couple of hundred miles to get the monitors ready. It took almost 400 miles to get my wifes car ready for a smog check.


This is the drive cycle from the factory service manual.

Got it, I had forgotten that was out there. Thanks for posting!

You pass like this. This is right after a reflash. EGR goes green pretty fast. I am installing an On3 single kit soon.

Is this a Lund nGauge? How did you get to this screen to check monitors?

Be glad, you guys that emissions testing is as easy as plugging a diagnostic tool into a socket under the dash. Texas first run at smog testing had exhaust pipe sniffers with the car up on an actual chassis dyno. Took 1/2 hour to do the testing and there were only a dozen or so test stations in the entire Houston metro area. To test a couple million cars every year. Ya right. I took my 89 Fox to one of them, early 1993. It passed, but it was bone stock.

Whipple stage 2 with their tune passes in NY. No cheating necessary.

Yes, it is a Lund nGauge. Diagnostics > IM Monitors.

Thank you!

It’s very simple, give them some extra cash. Pass every time.

How does that work for beating the OBDII systems check? Pretty sure you can't just plug it into another car and pass.
