Datalog on the Diablo reads better than .8 on all o2 sensors (.9= rich). how can i lean this out? already have timing maxed and wot fuel trim leaned to max.
please... before you blow it up pull the timing back and add some fuel... as jstreet said.... you NEEEEEEED a wideband to tune for WOT...t he stock narrowbands are useless for tuning.
