Probably will work I think Chrissie???? (Ragtop from here) worked out the signal once form a ford type speed sensor, my old EEC-IV OFAC one for the Fiesta Turbo worked but didnt give the correct speed, this didn't matter for boost control issues but meant the speed display was never correct i.e I would be doing 30 mph on speedo and AVC-R would say 60mph for example as signal generated from sensor was wrong frequency to waswas settable on avc-r
