7875 + 5.9 + E85 + Megasquirt
Got a response from SnakeEater. Their only suggestion is that maybe I don’t have enough fuel delivery to satisfy these thirsty injectors. OK. But even at idle they run hyper lean?
So I decided to just tune them. Reset my required fuel, dead time, etc to match the 142lbs, added a bunch of fuel to the VE table to get it to idle, added 20% across the entire table to get it going, still too lean off idle. Add 20% more. Now we’re closer. Enabled the AFR short circuit so that it cuts spark if we go too lean while in boost. I get into low boost, it’s still lean, add some fuel to VE table, hit it again and we’re rich. Come home, pour over the logs. Although it’s really rich and I know I need to pull some fuel from the VE table what gets me is that the duty cycle is essentially the same as my old injectors with all other variables being igual; TPS, RPM, LOAD, AFR, FP, etc. it’s like 40% duty cycle at 6psi which was the same as my old 80lbs.
:wtf:
