So i have both a 2018 and 2020 PP1 cars. the 2018 was a flood car (aptly named the U-Boat - i will be posting a build section soon) and the 2020 a wrecked one. I basically pulling all the electronics i need out of the 2020 and go into the 2018 (wiring, all modules, etc). The 2018 car will become a race car so all the havc, radio, interior (we have to keep the dash), etc. will all be removed. Its a showroom stock type class (T2 in scca) so most of the car must remain stock. Im trying to find out all the subtle differences between the 2 cars. I already see that the 18 has a couple levers below the radio and the 20 has 3 buttons, what are the ecu differences internal (rev match i know is one but any others), etc. Car is located at my shop in Marietta GA so if anyone on here is an actual ford mustang tech and up to date on the electronics side, would love to speak in person and even pay for your time/help on this. My 1st one (they are always the hardest) but prob won't be my last one. Thanks!
