    Everything is being R&R'd, including the diff, so it's a “now's the time/while you're in there”. Outer ball joints have all been replaced, RTAB's are Bimmerworld, camber arms are some ECS aluminum I had lying around, they still use rubber on the inner joint.
    I'm getting anxious to get this thing back together while the weather is cool

    Maybe I should make a journal…

    My dumb question is how to think about swapping not just intakes but the ECUs to go along with them.

    For California reasons, it'd be great to swap between the CSL intake & stock intake periodically.

    But my understanding is that an ECU really needs to be tuned (Alpha N, etc.) to take full advantage of the CSL intake. But that kind of tune is not permitted in CA.

    So the dumb question is: could I simply buy a second ECU, pair it to my car, and have it tuned for the CSL setup, then swap both the stock intake and ECU back every few years? Or is there a work around to have my original ECU do it all?
    that's what I'm doing. I have a 2nd ECU that has a "canned" tune from Kassel Performance that I run with my CSL intake. When it's time for smog, I swap it all out and put my stock ECU back on.

    Anyone running Powerflex bushes for the upper inners? I bought a set, was going to replace them last night while I was doing the ball joints, but ended up breaking my threaded rod and had to put it on hold.

    It doesn't seem like they would be a negative in that location, my original rubber bushings look great for 120k miles and 20 years though 😂

    Tempted to order a set of sphericals for it, but thought this the place to ask

    Yes you can.

    There are various things you can do with a "tune," and not affect the emissions drive cycles. You will need cats (in sect 1) or defoulers or something, and o2s installed ofc, but it is very possible.
