    If I understand correctly, most or all of these kits simulate a healthy system, sending the "expected" inputs to the ECU. If your inspection is purely computer-based like it is here in GA, without any type of visual/tamper detection as part of the inspection, it should be invisible.

    It varies from state to state whether or not you'll have a more in-depth inspection. And there are varying levels of SAIS bypass kits ranging from "really damn obvious" to "extremely easy to conceal".

    Like, the 1st generation of the Hewitt kit, to me, is really easy on the install, but a trained inspector could probably find it if they knew what to look for. The 2nd Generation of the Hewitt kit is far more concealed, but requires popping out your dashboard and soldering onto 3 wires plugging into the ECU.

    Ultimately, YMMV. I think it depends on your level of comfort and the severity of your inspection. There's at least one, maybe two guys from CA on here who've installed the bypass kit and made it through the CA inspection process just fine.
