Flat Shift on a Ford BTR? Hacking the Haltech!

In this episode of MotoringBox we’re getting all technical, as I explain the way I managed to get Flat Shift working on a Ford 4-sp BTR transmission! Ordinarily this is impossible unless the Haltech is controlling the transmission, which in this case it isn’t. But with a few workaround hacks, you can gain full ignition retard AND fuel/spark cut on shifts!
