[QUOTE="ZeroSVT, post: 14807114, member: 81012"] Thanks for responding. I agree that you should be upfront with your dealer and Ford. However, thats not the point i'm making here :) I'm asking exactly what tools you think us engineers have to see if a ECU has been loaded with an aftermarket calibration? PTDiag? Vodu? There are ways of guessing, but nothing definitive. Checksums do come into play when it comes to loading a valid calibration on the device. I was assuming you thought that the previous calibrations checksum values were stored off in FLASH somewhere, and it was extracted for verification. Not the case. (the most common guess though) To be honest, its hard to lock people out of ECU's now days, believe me. As you probably know, the TC series ECU's use 1024Bit RSA Signatures and about 70 checksum blocks. You would think virtually uncrackable with brute force methods... But here we stand... Picture of VDD (or some people may recognize them from hypertech) below. Was commenting on the similarities.... thats all I was saying :coolman: [ATTACH]40006.vB[/ATTACH] Cheers, -Matt [/QUOTE]
