I figured I should add an update on the current tune. I have been running pure Alpha-N for a couple years now, and this is the current state of the tune.
There is still a wee bit of unhappiness light-throttle around 2000rpm, and cold start is still about 10% unhappy. But very driveable, and nary a problem.
I did have a strange quirk wherein the car would act like it just dropped two cylinders, usually only once in a while, and only within the first 20 minutes of operation. Only a full on/off/on would make it go away. Someone on www.locostusa.com found the fix: reset “next pulse tolerance” normal running up to 70%. Problem solved.
