Return to stock
On 2011+ Mustangs:
Stock File->Write Entire = Return to Stock
Stock File->Write Cal = Return to Stock? If I write the stock Cal and have never done a Write Entire with any other OS, is it officially returned to stock or do I have to do a Write Entire. Please only answer if you're 100% sure.
How does P0605 play a role into this? Set it back to stock as well and if the Cal is stock it won't flag?

P0605 is set with write calibration, as it will know that the PROM has been modified. If the calibration is returned to 100% stock, a write calibration will not set a p0605...speaking from experience on both s197 and s550 cars. At least I didnt recieve that code and i had it enabled on both cars

Sweet so it must just do a checksum on the calibration and throw a code if it isnt right. Thanks!!
