So I’ve been running a few Duratecs “stand alone” with just the XR4
ECU,
Paired Cluster and obviously a key reader and Accel pedal.
It feels like 2007 all over again when I did this with a Focus set up.
The XR4 setup does have more potential “down the line” and now I’m working on the various bits of messaging needed to make the
ECU “more happy” about not having modules connected. It doesn’t actually generate a MIL and the engines run correctly but without a valid speed input the torque mapping is a little less good.
As it turns out it misses its friend the
BCM and well as the
ABS module (that’s quite obvious because that’s where road speed comes from).
For these standalone builds I’ve started working on a microcontroller that lives on the CANBUS and injects the messages needed to give some peace of mind to the
ECU. Using GPS for the speed data and so on.
On these the standalones we use either discreet instruments OR a Haltec IC7 or similar.
I still haven’t bothered much more with the PATS side of things.
