unable to tune
Can anyone help!!!!
if they were up to the present job they are too
limited. Some handhelds never did support '98s.
Any of the PC based tools will talk to a '98. You
have extra things to watch out for but you can
get it done.
Two, downstream sensors have nothing to do with
your AFR, and how you know your AFR without a
scan tool and wideband is a serious question too.
rear o2 sensors DO NOT affect the tune... i think you need to contact Frost and have a mail order tune done for 100$ bro.
