I have a 2018 Mustang GT, it had a locked ecm and the only way around this was to use use ford FJDS programming and a J2534 programmer to install a complete new ford operating system. This in itself was a massive pain as the ford software would not recognize anything with the locked ecm. Finally I have it working and the newest ford OS for the vehicle. HPT will now read and allow me to license. The car has a gen 5 3.0 Whipple installed and I would like to run the Whipple OS, so that whipple changed items like IAT2 off the former Runner control will function. With the help of a few members on the forum I was able to gain access to a couple of Whipple OS for the vehicle. Great, so now what do I do? I already purchased four credits and licensed the calibration from the ecm in the car, when I try to program the Whipple OS into the car it wants 4 more credits. I thought HPT changed ford licensing, to the vin and ecm serial number, so once I licensed the file pulled from the car that vin and serial where licensed. I was then expecting to send the whipple calibration to the ecm and be ready to tune. I sent HPT an email asking if this theory was correct along with a question about the locked ecm. They responded, about the locked ecm and nothing about my OS change so I assumed I was correct in my thought process. So what do I do next?
