My was hand written on the comp sticker "AF"
On the far passengers side of the firewall, a vertically mounted black box, has a 2"sq white bar code sticker.
My original flash was "AE", they have flashed it up to "AF" now on my truck.
I think they are up to flash "AX" now.
so I guess I need to do mine as well.
txag09, if you don't mind I am going to ask a related question in your thread.
My truck is all stock except for SC flashpaq.
I will eventually do a DPF and EGR kit, and maybe an MP-8.
Do I need to update my flash for any of those mods?
(Do some mods require certain flashes?)
Should I update my flash now, if I am having no problems?
Not trying to hijack you tx, but I bet would would mind an answer to these questions either.
