    Went another way and did my car with MegaSquirt3, works well now, 212hp/301nm.

    One thing, that I learned later was, that the Z3 2.8/3.0 were sold with Euro 2 (?) spec, hence no secondary lambdas and different exhaust manifold. Also the easiest way to skip the secondary lambdas is to reflash the ecu with Z3 software.

    Hope this helps someone.

      It's been 4 years since I've posted in this thread

      I just towed my E30 from Dallas down to Austin where I live now. I brought an M30B34 and my M54 along with me.

      The M54 was full of water, kids kept coming by and removing the tarp that was over it... I'm still wanting to use it though, so I'll be taking it apart and seeing what needs work. The camshafts definitely need replacing, and I'm guessing the crank won't be in fantastic shape. Wouldn't be surprised if a full rebuild is in order. I like that sort of thing though, so if I can do it I will. The engine was tip top when I pulled it, would be a shame to waste it.

      Anyways, I'm finally back on this. Just thought I'd bump this up. Pic:
