Removing Unichip from AU - Ford Forums - Mustang Forum, Ford Trucks, Ford Focus and Ford Cars

Can anyone tell me which pinns on the Unichip cable connector need to be shorted when I remove the Unichip from my AU?
Car is being sold and I want to put it back to standard before it goes out the door.

is the cable connector plugged into the port opposite the main wiring loom plug? if so remove it from there and she should be as good as gold

evilcheif: What ??!???

bobr: you need to find out which one is your "MAF" wire, and your Crank sensor - and + wires... esentially the unichip will "Tap off" your power, ground, Tps. however, it will Splice (as in, cut) your crank sensor wires (there's 2), and your MAF sensor wire..

not real simple to explain unless i saw the installation

Interested in selling the chip? I've got a Fairmont Ghia with the VCT engine.

Thanks for that.
I remember seeing a schematic a couple of years ago which showed a couple of connections which needed to be linked up again if the Unichip is removed.
Don't have a MAF sensor (XR6 not an XR8) but I'll have a good look tomorrow and see what I can make of it re the crank sensor wires.

Possibly - I do have a mate locally who is vaguely interested but before I do anything I need to find out if this version of Unichip is useable in my XR6T which arrives here this week.
Will check up with my local APS specialist here and see what he says about that.
I'll also be selling the Pacemakers, high flow CAT and the rest of the exhaust (H.M. Headers stuff) - all still in good condition but a bit difficult to sell outside of Tas due to freight costs etc.
Have to put the car back to "standard" as I'm selling it....

hi bobr, i think you will find that your Unichip will work in your BA XR6T..
you will also need a 2nd stage Unichip that goes with your Unichip it's a partner and is needed for the XR6T..

Great!

Looks like I'd better hang on to it then...
