So I've been looking into the rollback from PHP for my FICM and ECM/TCM and was wanting to know where the ECM/TCM is located. I figure if I have it done I will just send them in instead of waiting the 4-12 weeks on the remote programmer.
Sesco4 I actually just installed my FICM that I had reprogrammed by Bill at PHP to the Hybrid FICM calibration with the Inductive Heating Strategy Wednesday evening. I didn't have the ECM/TCM rollback because I had purchased a spare compatible ECM/TCM and when I installed and checked the strategy version. It was the same as Bill was going to rollback to.
To answer your question. The PCM/TCM is on the driver's side fender tucked behind the battery. You will need to remove the battery cables and the plastic battery cover that also covers the PCM/TCM module to help shield away water from it cable connections. It had 2 bolts at the top of the module that mount it. The bottom is held by 2 tension tabs that the module slides behind.
I would recommend looking into purchasing a separate ECM/TCM and FICM units to send to have the rollback and reprogramming done to. Because if for any reason your truck goes to a Ford dealership. There is a high probability they will reflash your truck, even without your approval or knowledge of them doing it. Then you will be back to square one. That includes even if you just take it in for normal oil changes or maintenance.
I do not know yet how much benefit as far as mpg I might have gained. I did notice that my truck seemed a lot more responsive and seemed to be quieter and had a smoother idle. Feel free to PM me with any question you may have. I just purchased this truck in Sept. '10 and have spent a lot of hours online researching to get the info needed to help make my truck as reliable and get the most mpg I can.
Hope this helps.
