did a couple of runs with and without water injecton. interesting how it leans the afr. they may not be line up quite right being done on the road. then overlayed
first one, both runs were done on same flat road in 3rd gear at 3000rpm and finishing at rev limiter(7400) . solid line is with wi. dotted without. water and full boost come on at around the 4sec mark
same thing but on a hill
