What could make my fuel trims go haywire?
Went from great (adaptation multiplication )
http://www.datazap.me/u/stanlalee/st...d-afr-and-wgdc to what the hell? starts out great until 3000rpm then boom. http://www.datazap.me/u/stanlalee/e3...back-last-tune fuel scalar is set to 1.24 for e30 on both logs. Same e30 fuel on both logs. Only change to fuel tables were a moderate bump from 11.21 to 11.81 in the mid/upper high load range (starting at 4500rpm). Boost and wastegate are the same. Also I notice on actual lambda one bank sure seems smoother and more consistent than the other. Overall everything is where I like/want it except the fuel trims that decided to go off the charts. |
