HOW TO: 2019+ Live Valve Recalibration - FORScan

[silverRap22]

Just recalibrated my 2022 37pp truck with 1600 miles, made a huge difference in ride for me, for some reason the rear was sitting at like -22 or over twenty on both sides. I removed all dead weight from the truck (myself and some stuff I had in the box), before doing the recalibration. After comming from multiple raptors I knew something was up with this new truck, it should have had a much better ride quality from factory.

I saw in the Gen3 forum someone mentioned you have to put the shocks in maintenance mode, but Forscan walks you thru it. If someone wants to post that portion of it, I can update the first post

I just did the recalibration on my Gen3 the same as I did it on my Gen2 and didn’t see anything about putting the shocks in maintenance mode, my calibration was way off just like the others stated, and now it rides much better.

Just recalibrated, my fronts were both -27mm and backs +3mm (Deavers+3). 2020, 68,000 miles, haven't Forscaned in almost 3 years when I first bought her. Used the same ODBII ELM327 compatible usb cable that I first used with my '18. Got the warning that it isn't recommended but proceeded anyway, it worked for the other stuff I changed. Can't wait to see if there's a difference.
Driven for the day and it feels like a better ride over RR tracks, speed bumps, etc. Not a huge difference, but it seems to have made a difference.

Sooo truck was sitting level when I bought it new. Started sagging pretty early on but replaced with +2 HD Deavers months ago. Finally got around to resetting height today. Still 1.00 in rear after reset. May try again after lunch. here is before

Did you by chance set 1/4 full tank? I think that has a bearing on the calibrated setting. I had a full tank, told forscan calibration that and ended up at -1 for the rears after calibration.

I had right at an indicated 3/4 so set it as such.

Thanks for this, had an intermittent stiff ride that turned into all the time and this fixed it. Rides as good as when i picked it up

I saw the pop up for it, wondering if I should have done it. Said to put it in N and depress the accelerator a few times within 10 seconds. I recalibrated and now I’m 9mm and 2mm front vs rear.

I would just go drive it and see what you think and you can always do it again.

Getting it working on a trial of windows 11, on a trial of parallels, on a trial of forscan was one hell of a feat for me. Def will need to go with a cheap windows laptop in the future lol.
