So as I posted in another thread I was bored today & tried a few things....
Another 1 I did was update a 2003 Falcon V8 Manual from A3KA, to a 2004 Falcon V8 Manual A3KD!
Normal if they start with the first 3 prefixes they are completely interchangeable, but when I did this I lost the speedo which then if it's not getting that can't make certain calculations & eventually goes into LHM!
Just wondering if anyone else has struck this with other models?
I'm guessing it may be when Ford went from speedo signal on the g/box to taking it from the wheel speed sensor & there needs to be an edit in the calibration to choose which signal to use?
