there are a few ECU updates, but they are for select cars and select problems.
mainly its dealing with a "check engine" light thats coming on occasionally from an incorrectly monitored misfire... the vehicals arent actually misfiring, but the software says they are.
thats all they are changing.. its loosening up the the parameters a bit.. and its only on a "as needed" basis anyway.
no worries... it changes nothing else on the vehical.
