A tune only, from either vendor, will still pass emissions.

+1, I passed emissions in Georgia with my whole package installed. But not sure on different state emissions testing, Georgia's test was only 2 things: gas cap and ODB plugin to verify no check engine lights. I don't think their (emissions testing facility) had the sophistication to know what was a "stock" vs "custom" tune. Their machines basically just make sure you aren't driving with 10 (or just 1) check engine codes. Which in my opinion, is just another reason the states or counties are ripping of citizens. Oh well, probably for another discussion.

They are both excellent. With unleashed you aren't forced into buying certain items for tunes. Such as I don't have to have catback exhaust to run methanol. Where as with LMS they would require it. That's why I went with unleashed but once again both are fantastic

Maybe I'm missing something here. I'm running LMS tune, DP, and methanol (straight M1) all installed by Livernios with stock cat back.

What he's saying is that if you choose LMS tune, you are forced (in certain mods) to use LMS mods. For example, LMS will NOT tune a snow performance meth kit. LMS will only tune for their meth kit. As long as you're buying all your stuff from LMS, you're good.

I think what he's saying in his state they actually plug into the computer to make sure the computer is ready. When you disconnect your battery and reconnect it there are several miles one must drive before the computer gets everything "checked out" and it's ready. What he's saying is apparently on his tune LMS has disabled this so it will always read not ready. Normally I've seen this happen for keeping the rear O2's from throwing a CEL.

If a state is just looking for codes they won't find any. But if it's a state where they plug into the car and actually read the status of everything, it will say not ready and they'll fail it until you bring the car back and it's status is ready. The reason is because some people will disconnect the battery to clear the CEL, bring it in for testing, and try to get it to pass before the car runs through everything and brings the CEL back on.

Regardless, a true "tune only" from either primary vendor, accompanied by no other mods, will pass emissions.

IIRC, the procedure you defined, it takes between 100-250miles driven, in order for everything to "reset".

I don't have testing so I haven't looked into it. The only thing I have is what the poster stated...."the last dialog I had with LMS was that they never turn on the "readiness" indicator"

Well I was just offering real world experience to his question - if either (LMS or Unleashed) offer tunes that will pass emissions. Yes. I have a LMS tune, I lived in metro-Atlanta which required yearly emissions. I passed.

But to his 2nd point, and yours. I very much agree... I'm not sure what the difference is between state to state. If the test is looking for anything more specific than CEL's... it could pose a problem, depending on what it's looking for.

And honestly, like you said about people unplugging their battery and then going in for a test. That is my exact point to the absurdity of the state and counties. The mass majority of people that this is impacting are the financially hurting people who are unable to fix and/or drive nicer cars. So why on Earth you would want to impose taxes or fines on those people and not allow them to renew their tag is unbelievable. In Georgia, cars older than 20 years or something are exempt. So this whole emissions test really exempts most of the people who build hot-rods (which are probably much worse on the environment vs a 1998 Honda Accord with a CEL on). It's like "Let's penalize the poor people and make them pay more or keep them from driving". Really? If it's really a smog/emissions test - do it like Georgia in the old days - stick the wand/sensor up the tailpipe and measure the carbon and actual smog output. Then you're at least helping the environment. Now it's just another money grab by the Government. Aren't lawnmowers and tractors way worse than most all cars on the road?

Colorado changed the rules last July (I think it was July) so now cars 0-7 years old are exempt, but cars 8-12 years old must pass the obd2 plug-in test. The pcm must be "ready" and have no codes that result in a check engine light. Failure to be "ready" results in a no-test, and a check engine light is a fail.

After 12 years old, if the check engine light is on or if its obd1, then they do the dyno sniffer test.

or, if you happen to get 2 passing results on the roadside test in the right time window (2-6 months before your registration needs renewed) then you don't have to visit the test station.

So, in Colorado the fact that the LMS tune (at least used to) never sets the "ready" condition would mean you could never pass emissions here. One of the annoying things about the whole emissions testing racket is that the rules are not consistent from state to state, and they change regularly.

Angela, the lawnmowers typically run for a total of 4 hours per year, so even if they are not very clean they don't contribute much to emissions. virtually all farm tractors are diesel but there are not many of them compared to automobiles and trucks so its not that big of issue.

What I find very curious is that the auto emission fanatics tend to be tree-huggers, and every one of those wonderful pine trees we have here in Colorado puts more hydrocarbons into the air than any auto is allowed to...
