This is my commanded afr table. The other reason I was asking, was because at some points, I can watch my AFR go crazy. It will be at 14.0, then 15.1, then 14.8, then shoot up over 16.0, sometimes to 17 or 18.0, then come back down to 14 or so. It does all this in a few seconds time. I think I just need to let it autotune more in that area, maybe EGO is is trying so hard to correct it. Maybe smooth it out better.

Data logs are a thing for a reason. PID EGO can do that...

Targets like that must mean you are in 1.6 master race. Buy newer injectors and the sequential board, that will save more mpgs than anything.

Yeah you must fix ego. But also should get the map decently close without ego for the end result driver you want. Keep in mind stock ran at 14.7 everywhere but wot. And even in boost you are aggressive. Clean up afr and get ego working right will net you much better cruise

I have 610cc injectors to put in and tune. Will be interesting based on this thread if I still hold my afr numbers. Btw. My cruise low numbers are at 4350 rpm and some kansas winds for mpgs in 30s.
