PI/DI ratios idle stability and knock

@sav

you might try a couple of these tweaks to pi/di ratios
alter all three tables
cold/warm/hot the same

zero out the PI up to 0.2 load this is idle for manual, makes it idle smoother and you can drop your idle back to 700 or even 650 rpm.
doing that also stopped the idle dips when air conditioner kicks in as well.

On an auto zero out to 0.3 load as it idle at more load due torque converter

you might also try altering the rpm axis where is 5200 to 6000 so it runs full DI up to 6000 or even try 6500 as DI generally more knock resistant

seethe linked info below from moto mike about max pulse widths ect.

on E85 we are actually holding full DI to 7000 rpm.

I have also altered the values in the 2400 and 2800 rows to max of 25%

you might be able to put back a bit more ignition advance doing that.
