noob here. i'm trying to figure out how to change the BPW in TunerPro and i can't find it anywhere. there are lots of other tables affecting various circumstances like inj pulse width vs. battery voltage etc, but i dont see BPW or any kind of fuel map. im using the $6e, 165 ecu and the apyu bin. so if i'm running rich/lean at a certain rpm then how do i tune for that?

 

Should be in the constants area, I think.

MAF systems go by airflow, so the fueling isn't rpm related in a table like you might imagine where it's afirflow vs rpm.

you want to look for the MAF tables to adjust fuel at different airflows.

 

in funstick's maf tuning article he shows a table which he calls "BPW vs LOAD, msec of inj PW" and it shows rpm vs airflow gm/sec. he states that this is where most of the driveability tuning takes place. i am using TunerPro and that table isnt even showing up. can anybody help?

 

yes and that is with code mask $32b. your using $6e./ the only 2 ways to affect fueling when not in PE mode is to either dick with the injector constant which will add or subtract fuel globally or use the maf tables themselves.

 

funstick, would you recommend switching to the $32b ?
