If you're in the process of adjusting things and tuning, here are some tips that might help...

- Skip using any mixture of meth/water and just use straight meth. I tried 50/50 and 70/30 mixtures, and while the bit of water helped cool the BATs, I wasn't able to advance the timing as much. It seems the MZR DISI engine loves the huge octane boost from running 100% meth. I'm up to about 20* of timing and still no knock.

- I'm using 2 nozzles, 0.8mm + 0.9mm

- I'm running the system off IDC only and looked at my datalogs to set the threshold. I wanted it to start around 5-7psi, which was about 36% IDC for me. The threshold trimmer is set at 42% at the 12 o'clock position. One tick mark to the left is 36%.

Thank you for the tips! I am in the very begining of tuning, running on 22 psi and 91 fuel, but haven't finished my tuning process so far. Halfway I had to switch from fmic to tmic because of endless issues with blowing or leaking silicone and piping.
I will be running 5 small jets: 1 pre tb jet and 4 direct port jets, but first I need to do all the primary adjustments with a single pre-tb jet.

What ambient temperatures are you running at?
Do you have any knock at partial throttle after long idling in a traffic jam?
Do you have stock internals?
