I downloaded the newest version of FORSCAN, I am using the OBDLINK EX, updated all my drivers and firmware, and I am not seeing all the modules?
I need to calibrate my speedometer for larger tire diameter and need access to the Body Control Module but I am only seeing a handful of modules. Is there something wrong here?
You may not be able to change the speedometer. The GEM is the BCM on older vehicles. Looks like the 2011 F150 spreadsheet is the oldest and it shows a BCM.
Tire size is in the VID block in the PCM in revs/mile. You need the Forscan beta version and a dongle like the VLinker FS with FEPS capability to change anything there.
You then still probably won’t be able to do much changing because the min and max allowable tire size is set in the background and the VID block allows you to change anywhere between the min and the max. Only issue is the min and max is set very tight allowing little to no change. To change the min and the max would require a tuning device.
