I love my L800’s but I can’t seem to get a good Dirac calibration. I run Dirac with SDA off (unplugged) and can’t seem to get it dialed in.
Anyone have success?

SDA cable unplugged while taking measurements is good.
I've never used Dirac, however, I have used ARC and it worked OK. In actual use I don't use the AMP that had ARC, I only used it to help me get a picture of the sound and point out any issues. The ARC measurements were taken from 5 positions centered on the MLP.
Are you running the L800 for music or home theater? What issues are you running into running Dirac? Are you trying to solve an issue with Dirac?
I ordered a umik-1 so I can measure with REW without having to change out my amps to something that has room correction like Dirac, audyssey, room perfect, etc.
Here's what my ARC measurement looked like before I moved. I'm in a new house and will need to do new ones. The hump on the right speaker I'm pretty sure was due to room gain because I had a cabinet right next to the speaker, the bass on the left was not as affected by the room because bass would run into an opening to adjacent rooms 20' away to a wall on the left.

Dirac is pretty finicky as a platform. The issues I get are the delays and trims are off (that should be easy part). It “centers” the stereo image way left. I was able to get it to center, some how, some way and it sounds great! But I can’t repeat it.
Somewhere on their roadmap is to allow manual adjustment of gains and delays.
Also, it doesn’t like my subs on a minidsp, when the biquad PEQ is on, it jacks up the delays to the limit of my AVR (25ms).
Overall I’ve been happy with Dirac but it’s inconsistency is challenging. I’ve always had my eye on ARC genesis. I love my anthem amp. Apparently ARC hasn’t been smooth sailing either.
