i did a custom 5 operating system on a stock ws6 with headers.when i went to do the auto tune its lean.comands 14.00afr and wide band reads 19 to 20 afr so i change the comand with bidirectional controls to to 13.7then wide band goes 12. afr like it should.(should be fat i add little fuel like a allways do befor i do a auto ve).so i build a custom operating system 3 that i allways use and have made work fine many times does same thing lean. then when i hit bidirectional controls 13.7 goes fat like it should.so i unhook the mas air and goes fat like it should.so i think ok its not going into sd. and needs mas air unhooked ( not sure why i have left them on befor and works setting every thing like the tutoral says)so i make a hose to replace the mas air put it on so theres know mas air.reflash the custom 5 and bam does it again now i am lost again. heres the tune and 2 logs first log shows how lean it is. in the second log i hit the bidirectional 13.7 and you can see it go fat. both logs are off this tune.not sure what i am missing but its probly simple helpp. simple sh__ kick my ___
