I pulled the trigger on making some FORScan edits this morning, it ended up being a very easy process thanks to all the tutorials out there. I did run into one issue along the way that ended up being a slight defect with my OHP OBD2/USB adapter. Every time I connected the truck to FORScan and had to flip the switch from HS-CAN to MS-CAN during the connection process, it stopped reading and adding modules. After trying different settings and re-trying connections about 10 times, I thought that maybe there was something physically wrong with the switch on the OHP device. I pushed the switch a little harder when prompted, and it read all the modules as needed. Ended up working fine, the device just wasn't 100% perfect.
So if anyone is having trouble during the HS/MS switch, try using a little extra force on the switch itself.
I ended up doing the following edits: Lincoln mirrors, disable auto stop/start, window roll-down/up from keyfob, added heated/cooled seats and heated steering wheel to home screen, added temp readouts to gauges, DRLs. The amount of customization possible is very impressive.
