ok did a auto ve every thing looks good repeats. so i turn on the maf (closed lope with lt fuel disabled so lt fuel doesnt come into play )and tune it get that straight.so i turn on lt fuel trims and it starts showing lt fuel being added some places over 20%.so i go back turn off lt fuel trims air fuel maps are great with no lt fuel trims.turn back on lt fuel trim starts showing lt % high in places again all this time i have a wided band logging maps with or with out lt fuel trims on afr is same. its like when you enable lt fuel trim it takes fuel out of the ve then adds it back in lt fuel trims.looks like its lean in places where it adds it in but once it lurns its self it reads same as if lt fuel trims are disabled.i have be over this 10 times.when i use the efilive custom operating system with the autove works great st fuel trims look great man wish i could sure it on every thing.
