Ef computers??

Does anybody know how to fool an EF/EL/AU auto computer into thinking the box is permanently in neutral?
I'll get the wiring diagrams off Ford tomorrow, but I doubt they'll help - has anyone heard of this before???

It is possible, however you will need to use resistors, with the correct value so the ECU thinks the shifter is in P or N.
Alternatively you can bypass the inhibitor switch also.

You will need to trick the ecu into thinking the solenoids are still connected though - this should be possible with some high wattage wire wound resistors.

If this can be done, I might consider the manual conversion, as the ef xr6 manual computer is the most expensive part of the conversion..

If there is any general interest in this, let me know and i'll take the time to look into it, find out exactly what needs to be tricked - then someone will need to try it to see if there is any drivability issues....

Just finished putting a V8 manual into my Fairmont was a pretty extensice job, with the computers we used the XR8 ECU with the Fairmont BCM and everything went together with minimal dramas.

If you are going to a manual box you will be best off running a manual ECU as you may encounter issues with the idle and also you may find the computer drops into limp home mode and you have bugger all power etc etc not too mention everything else that could go wrong.

Can't stress the importance of having the right computer with the right drivetrain, the EEC are bloody tempremental things and unless you want ongoing issues with your electrics which will prolly cost you the same if not more to chase in the long run go with a manual EEC.

If someone is doing the job for you and you have warranty recourse then that's a whole different story, but remember there is different computers for a reason.

Regards

Daniel

With a V8, you just have to disconnect the trans computer. In the 6cyl, you just have to short two of the trans wires together, just cannot remember which ones sorry. It has been done before without any drivability problems, because basically, except for the trans components, the auto and manual EEC's are basically the same.
