I used a stock F150 PCM, BCM, BJB then built my own harness to make it all work while maintaining PATS, TPMS, Cruise, AC along with full onboard diagnostics. Since the engine was a new Raptor Crate engine I also had to program a 10R80 to work in sync. It was also wired to have adaptive cruise but once on road just drove it.I'm sure you posted this somewhere, but what are you using to control the drivetrain?
Base tune on E50 it made the 603 hp 658 tq at tire on a 100+ deg day. I did upgrade the intercooler to the Garrett and built proper duct work. It made a massive difference in power. Stock frame, original to truck I beams and diff. I switched to a quick ratio PS box and brother designed the sway bar setup. The Baer Brakes were fantastic stopping in under 3.0 seconds 60-0.
Traction control was limited by right foot or 80 mph
Last eco swap I did I maintained trailer sway control, anti skid, anti roll, full abs, satellite radio. Still hoping to do another with a twist. 2023 F250 6.7 H.O. 500/1200 with full electronics inc Co-Pilot 360, 12,000 lb winch dropping a 1965 N7000 cab on the new F250 Chassis. I ordered the truck (4x4) but few more things have to come together to make it all happen.
I need to make more progress on my 1966 N700 getting the 2023 7.3 Zilla swap and possible Whipple . .
