Accidentally bricked PCM - any hope for reprogramming?

[warren8r]

Hello,

Needless to say I made a big mistake and accidentally erased my PCM. I would assume there MUST be an image of some kind associated to my VIN that I can reflash?

Thank you so much for your help!!

I d guess the dealer will be it. Also call a aftermarket tuner, maybe they can help.

FORScan?

I would ask first if you tried a firmware update on the PCM or you just overwrote the ASBuilt-data?
If firmware update you might have luck with the paid license of ForScan and the current beta built, which is able to rewrite the stock firmware (if ForScan is still able to read the build number from the PCM). If AsBuilt data any version of ForScan can write the AsBuilt data (you can download your stock AsBuilt data from motorcraft website).

Great question. As a matter of fact Forscan is helping me rebuild. It turns out it was misdiagnosed. PCM is intact (thank god) but FORscan returning error as if PCM erased (2.4.3 beta).
