hi guys finally got my iroc on the road,and installed aem wideband.......open loop is very lean off the scale! im using 165 ecu with an ostrich 6e mask,the bin is basicly stock 89 5.7 tune with lean pop adjustments made for HSR..and arap spark map..car runs fine in closed loop ( ecu is adding fuel) but open loop is very lean, where and which tables should i start changing to enrich open loop?????

 

MAF tables. See the Tuning Guide Book sticky, in the '165 chapter for information on the MAF tables and scalars.

so basicly go into the maf tables and increase the values to get the a/f ratio to were it should be??? and then continue to adjust the tables after its in closed loop to get the blm's as close to 128 as possible??? or am i oversimplifing it??? ihave read a lot of the tuning guide and am still a bit confused ...... wot is almost perfect at 12.8 a/f will adjustingthe maf tables affect wot(PE) or is that strictly in the PE adjustments?? thanks for your help
