I got mine fixed at FICMrepair.com.
Ed did a GREAT job.
He said that the 58v can make them less reliable ?
I went with the upgraded repair for $325.
My FICM is also tuned from PHP and that made a nice improvement and a 1-1.5 jump in mpg's.
FYI with Ed the repair is the exact same no matter what you pay for the unit. The difference in cost just covers the length of warranty.
