Okay, got my OFT, but the paint on my DIY bumper exhaust exit cover (I have a single tip exhaust) is still drying so I'm not flashing any tunes and driving.
As you can see, the blue outlined cells were leaned out. Max g/rev on this engine is like 1.33g/rev or something so 0.7 is 53% load, and 0.8 is 60%. Now I can pulse at 53% load on the freeway without triggering enrichment, and up to 60% only going a little rich.
Right now I have around 1.4 gallons E85 to 6 gallons gasoline in the tank, which is a blend of 89 and 91, so it's around 25% ethanol and should be like 96 octane or so, but I pulled 0.5 deg timing on this map just to be a little more safe.
You can also see I've lowered all the idle speeds, I'll see if 600rpm warm is good. I'll try 550 and 500 as well hopefully.
I don't know which "Requested Torque" (A, B) map is the primary throttle control map, and this off the shelf tune already has adjustments so I'll try it first tomorrow. If I don't like it I'll make some changes when I figure out what table does what and reflash.
As for lean burn, here is my progress:
O2 sensor rescaled, AFRs adjusted to approximately where they were before:
Cells adjusted back to "14.7" so that the thing actually learns to run lean, plus small timing tweaks to make myself feel better:
To translate into actual AFR, multiply by 1.099
The 13.34 cells are just barely leaner than stoichiometric, and because of rounding errors the rest of the cells are also leaner by a tiny bit, since you can only add fuel in 1/128 increments (to lambda).
Doing the cams will be a challenge because I'll have to log manifold pressure with different cam settings to determine if anything would help.
