Crisby FFH Report post Posted October 13, 2022 Hello, I'm new to the scene and have got a 2011 FFH. The car recently pretty well stopped EV mode and I ran a cross this forum and applied the battery age fix with forscan. The battery age fix seems to have brought the car back to life, although I have an issue... I have been experimenting with the "State of charge" and "State of Charge 2" values, which I am learning now was probably not recommended... SOC value has a direct effect of the dash gauge, which I believe is the "usable SOC" I want to go back to the old values that I had just after I changed the battery year back to 1 (2400), What ever I have done to the SOC and SOC2 values has left the Battery Charge gauge on the dash full to the top almost all of the time and the EV mode cuts in and out in intervals that seem quicker than normal. I was monitoring the pack voltage with forscan and noticed while I drive the Voltage tries to stay around 305 volts when the SOC% value is 95%, During EV mode it will deplete to 91% (~280volts) and then the ICE will kick back in and charge back up to 95% SOC ( ~305 volts). Using the top 10% of the battery scares me and I think I may be damaging the HVB. Notably at this high voltage , The car has significantly more torque from a stand still and will actually creep around like a little diesel with no throttle input. Further worsening my problem... some how I managed to delete my original BECM asbuilt backup file that I had though I diligently saved (LOL) and now I'm a bit lost as how to restore the BECM SOC and SOC2 values to make the car use the middle of the battery range and get the dash battery gauge back to normal. I'm looking for Asbuilt BECM Hex values to borrow if there's anyone kind enough out there to share theirs. Alternatively , I have heard Rumor that the TSB 20-2142 re-programming (BECM and PCM) at a FORD dealer is even more beneficial than the forscan battery age fix, and I am contemplating just going that route which I hoping this would would give me factory asbuilt values again. 2 hour drive and $200 at the dealership tho ?

billford Report post Posted October 15, 2022 Your better off updating it the official ford way. The ford way usually updates several modules at the same time. Its ok to use forscan to monitor things, but I would not do any unofficial programming with it. Asbuilt is vin specific. You can't share the data between cars.
