    Need a little help here.. 2018 Raptor, 802A, made a few FORscan mods and each seem to be functioning as it should. I made sure to document the original value for each Address line I modified. A day or 2 later, I decided to go back in & create a backup of each modded module. Before doing so, I went back & checked each module/address modded line, to be sure my value entries were accurate. I noticed that several values were different than what I had entered. I'm a bit freaked out now & know that I did not make an entry error. I re-checked 10x before hitting the "Write All" button. IS this normal??? If not, can anyone share advice? Thank you...
    Here's a look of the modules/values:

    By the way.. I'm using the this OBDlink:

    I’ll close my own loop here... Since I received to replies here, I posed the question in another forum dedicated to FORScan... The question was answered there & it was noted that “checksum bits changes automatically”. I guess it’s normal for your entered values to change on its own after you save and exit. So long an your tweak works as intended, there’s nothing to worry about. I’m sure they’ll be at least 1 other closet newbie out there that will find this 2 post thread helpful. Maybe.... :biggrin:

    Hey RN201, thanks for doubling back on this post. Just found it and your FORScan changes are EXACTLY what I'd like to change on my 2018 802A! Just a bit apprehensive about changing the code, but going to try it one of these days.

    Question: does the global open/close also operate the sunroof?

    thx!
