i have been looking at doing the el computer into my xf ute with a 250 efi xflow.
but from what i have read its nothing but trouble or at the very least a bit of a headache .
so i have been looking around for an alternative ,
i have injected a few cars before and have used a microsquirt on my old 57 kombi , with twin
44mm throttle bodies (motorbike) on my 2276cc motor ,running a 36 to 1 wheel with hall sensor
and also running ls1 cop (no dissy).
i have also run a megasquirt 2 on my ls1 turbo hilux .
so was looking into the megasquirt pnp for a 5ltr 86 - 94 mustang or the
microsquirt with the pnp wirring adapter to the mustang eec-iv plug from efi source in the usa.
after having a good look at the pinouts from the mustang and the xf ,all the main sensors are identical.
i will have to make sure no wires are on pins 12 – 15 – 42 and 31 – 43 – 52 as these are ones the xf doesn't use .
12 15 42 are all additional injector channels on the Mustangs pin 31 is a PWM output intended for a boost controller output.
pin 52 is meant for another injector output, pin 43 is meant for one of the factory narrow band O2 sensor inputs.
and i will need to connect pin 1 to the positive terminal of the battery. This is used to dissipate extra flyback voltage created by the ECU ,so has to be added.
here is the pinout for the xf http://www.fordmods.com/documents.php?d=43
here is the mustang pinout.
