Megasquirt EFI Lean Cruise Reality Check

Following up -

1.) Rotor Phasing
Pulled the cap this weekend at 30 BTDC and the rotor was quite a ways off from the #1 cylinder.

I installed the new one using a process similar to 67darts' procedure and from the Megasquirt website. I am planning on running a max advance of around 50, and a minimum of around 10, so I split the difference. I moved the crank until it was at 30 BTDC, pulled the cap, installed the adjustable rotor (MSD p/n 84211) directly pointed at the #1 post. Things improved dramatically at high advance, but I am still planning on drilling the cap and watching very closely to get it perfect.

2.) Tuning - mostly for someone reading this in the future.
After getting the rotor phasing mostly squared away, I went back to my original ignition table shown above. I have since brought back total timing to around 40-42 degrees at lean cruise which I have been able to have run nicely at around 14.8-15.0:1. I can go leaner, or with a bit more advance, but I'm not going to push to hard until I can get some miles to really study how the car responds to tiny changes.

As for the popping on decel and highway - adjusting the rotor phasing got me about 80% of the way there. I still have an occasional puff from the exhaust at highway cruise, but I still have more adjustments to make and I want to confirm the rotor phasing is perfect. Decel popping was still there after rotor phasing, but was reduced to about 50% of its original intensity. I started fixing this by tweaking my VE table manually under ~40KPa until I was seeing the AFRs I wanted at cruise. I now stop the Autotune from touching anything under 40KPa, just because it's too hard to tell cruise from hard decel.

After, to get rid of the pops, I added in a fuel cut after 1 sec of MAP readings under 40KPa and a TPS of <10%, which has eliminated 99% of decel popping. I still have some work to do there, but it is dramatically improved.

It is important to note that I am by no means a seasoned tuner, this is my first full year of working this system out. These settings are just what I have found worked for my setup, and has given me a basis to go off of while being drivable.
