Engine tunes recommendation?
While I am still deciding whether to get engine tune or not, my amateur research shows that Evolve receives really good review on the forum.
A friend of mine told me ESS also provides tune but I did not see any vendor carry them (only the SC kit) I also heard about GIAC & Eurocharge (pardon if the names are incorrect) I would like to hear about reviews of any tune you have or encountered. Thanks |

Guys on here are just gonna tell you to search man lol. My buddy and I had our cars tuned at Gintani and I love mine and I know he does as well. The guys over there are awesome to deal with but to be fair I've only heard good things about most of the other tunes out there as well. My two cents would be just to consider whether you would prefer being able to drive down to a shop and actually speak to someone in person or have a cable mailed to you and then if there are any problems having to deal with emails and waiting.

With the Evolve tune, the rear O2 sensors will pass readiness which I assume means they are operational a greater range to prevent a CEL. Since minor adjustments to the mixture are made based on the rear sensors, this feature is enough to seal the deal for me. No other tune has this capability as far as I know. From what i can tell, all others shut off the rear sensors to prevent a CEL which causes you to fail inspection and lose the capability I described above.

Our off road catless tune is designed to not throw a CEL for catless exhaust systems. We do this so that customers who run catless systems can and will have a working CEL if there is a real problem with the car instead of having it always on. This is very helpful for cars that are being run hard for track use. Although our system deactivates the readiness monitors when the vehicle is catless it will automatically activate the readiness system if you re-install the catalytic converters. This design allows the customer to be emissions OBD compliant if they re-install the necessary hardware to do so. |

There is also Vishnu PNP tune that also allows you to run meth safely with GREAT power gain. I made 400whp on just proceed, meth and magnaflow exhaust.
http://www.m3post.com/forums/showthr...hlight=proceed I also had the Gintani tune for a year. Good guys over there.

So it's more illegal to run with the sensors on with an increased range than off? |

the issue is that they will appear not ready and will fail any emissions inspection ASAP.. In my state there are no inpsections for emission or safety. We do what we want |

What I want to know is if it is "more illegal" to run with the sensors operating with a modified range (no CEL, functionality retained) than to shut them off in case I get busted by 5-0 sometime between tests (CA has smog check points). The reason that I ask is that I want to retain functionality of the rear O2 sensors if at all possible because the car uses them for more than just monitoring cat efficiency from what I understand. |

If you're serious about power, this is the tune (accompanied by proper matching of upgrades) to have.

If you are concerned with being 100% emissions compliant at all times I would suggest keeping catalytic converters in the car. |

I'm not looking to trick anyone. My car will be 100% emissions compliant when it's tested. It's highway patrol and emissions checkpoint traps that worry me. I am attempting to determine which provides less legal risk in such a scenario. Is leaving the rear sensors on with an increased range going to increase my legal risk in such a scenario above and beyond simply shutting them off completely? |

This option is not recommended, and irrelevant if you are planning on swapping back to your OEM X-pipe come test time.

As far as I am aware, the rear O2 sensors monitor catalyst efficiency and mixture adjustment is done with the front O2 sensors, if you have documentation that shows the MSS60 DME uses the rear O2 sensors for mixture adjustment I would like to see it. The Advent of the rear or post cat O2 sensor was as a result of emissions regulations requiring that manufactures showed that the catalyst were operating in a specific efficiency range. Once out of that efficiency range the rear O2 sensors tell the DME or ECU to set a MIL/CEL light stating the vehicle is operating at increased emissions levels. In this case the increased emissions are due to catalyst efficiency being below threshold. To the OP, spend some time on here searching and I am sure you will be able to get a good idea of who you want to use for a tune. Reading the many, many reviews on here will give you more information than just asking what tune people think you should buy. |

BTW, it's usually not a good idea to admit on a public car forum that you're committing a federal felony by knowingly installing something on your car that was designed to trick the federal smog laws. Just saying. |

Also - to people arguing semantics over tricking the readiness - removing or tampering with your cats is also against federal law (assuming they are working properly)...So as soon as you took off your stock cats, you already broke the law. Just so we are clear : ) |

If the rear sensors are for nothing more than monitoring cat efficiency, this is all a moot point. Because that's the ONLY reason I am interested in keeping them operating; if they serve another purpose. I'm not trying to trick ANYONE. |
