Re: WQ Fiesta XR4 Diagnostics/OBD2 Reverse Engineering

Having a bit of a read through this thread, I noticed I had never pasted the results of my success in getting the EHPAS to power up on the bench.
There's a similar message to turn on the EATC as well.
All of these messages, by the way, are sent already by the current XR4 modules, so once installed they will all power up. For the EHPAS, however, the question still remains as to whether the Fiesta messages for speed will be useable by the Focus pump controller or not. I have already seen quite a difference in the message scaling for the Fiesta and Focus road speeds in msg 080.
