Re: which Falcon XR6 4.0
oooook, this is were it gets complex.
EB2, ED and EL are 60 pin ECUs. EF and AU are 100 pin. The difference being EB ED and EL have a dizzy, EF and AU are coil pack. Forgot using a 60 pin ECU with a coil pack engine and vice versa.
EB2 and ED wiring looms are the same. EL is similar to EB2 and ED. EF and AU are similar to each other.
The pin outs for EB2, ED and EL are the same, just the EL has a few extra pins for thermofans, knock sensor and the BBM manifold.
You can put an EL engine running EEC V into an EB2 or ED using the EB2 or ED loom. You just have to use the EB2/ED lower thermostat housing and lengthen a few wires on the engine loom.
I have an EB2 4.0 with an EL BBM manifold and EL ECU. It runs fine, with the exception of my trip computer, only average speed works on that anymore (well not really, but that's not the ECU's fault).
The only real difference between the E-Series 4.0 engines is the head anyway.
Any more questions, fire away.
