Hi, I changed the Fiesta MK6 engine from 1.4 to 1.6 (petrol). I haven't got ABS and the 1.6 ECU requires it. For this reason, my speedometer is not working. VSS is in the gearbox, but the 1.6 ECU does not communicate with the VSS signal . Is it possible to solve this problem without installing ABS? Or will operate 1.4 ECU to 1.6 engine?
