What is the best way to determine the actual ECU flash rev level other than trusting the dealer's campaign sticker or the Mazdausa site?
I have a Scangauge II, but not sure if it will read the flash revision level.
I supposedly had the MSP16 performed but wanted to check the dealer.

Hmmmmmmmmmm...................I don't know of any way with the Scangauge, but if you ever do..........be sure to let us know.
Send a PM to DarkBrew and see if he knows of any way.
I'll try some things and see if I can somehow tell and report back.
