I know this is a hella old thread but maybe someone on here can help.
.
I have just finished a very successful transmission swap between 3 cars. most importantly I have just put a 5spd box into my nf fairlane ghia. car has started and drives great, only 1 issue.....
.
when I roll up to the traffic lights and push in the clutch, the car seems to rev up to the 2000-rpm area, then it drops back down to idle after 5-10 sec's. I cant seem to find any vacuum leaks and am wondering if I should reset the base idle since it is a new ECU.
.
also, was wondering if anyone could tell me how to "trick" the auto ECU's to think they are in N.
.
anyway, until I hear a reply, im going to look around for vacuum leaks again :roll:
.
thanks

When you say it's a new ecu, is it an auto or manual ecu?

This is for a manual ecu, in a car which was previously auto.

As far as wiring, you can bypass the neutral safety by a link in the rectangular plug behind the inlet manifold, between the two wires that went to the inhibitor switch on the auto (the square 4 pin plug, the other two wires are for reverse). This allows you to start it without having to select neutral.

To tell the ecu if it's in neutral or in gear, you need to use the auto wiring plug (the round one behind the inlet manifold) to connect to the neutral switch.

I can't remember the color of the wires on the trans end of the plug, but on the engine loom side they are black/white and pink/light green (on my EF Fairmont).
Easy Way to check you have the correct ones, on the rubber seal in the back of the plug they have a ▶ pointing between them (not the arrow pointing out).

You should end up with two wires from the rectangular plug linked, and two going down to the reverse switch.
And two wires from the round plug to the neutral switch.

For auto ecu.
You still do the same with the rectangular plug, but the round auto plug will need the resistor trick for neutral and temperature.
Also the auto ecu may cause rev hang as the idle speed control settings are different between auto and manual ecu's.

thanks heaps mate, its a good read... and as for my ECU, im running a manual ecu from a factory fitted 5spd gli.
.
could you also tell me how to get the cruise control to work in the fairlane as since I have changed the ecu, it wont enable on the dash :cry: was a real pity as I was looking fwd to using the cruise.
.
thanks again

Sorry mate, not sure about that one.

It may be that the gli ecu doesn't support cruise control?

I had a gli EF Wagon (auto) which was optioned with cruise, and it had a NF ecu fitted, possibly to support cruise.

I'm still using the factory Fairmont ecu in mine, but with a J3 chip installed and running a modified Tickford Manual tune. I have also used the NF ecu in it, with chip installed, same-same.

Someone on here will know for sure if it's the ecu change that has caused loss of cruise control.

cruise control has nothing to do with the engine ecu. it has a module of its own.
I would be checking the brake light switch as you would have been down there fitting pedal or pedal box.
no brake light=no cruise control..
another thing is your car wont have the wires for the cruise control clutch switch.
your cruise control can still work but if you push the clutch in while using cruise control you car will rev its nuts off lol

:lol: yea I have done the usual checks and the cruise was working fine before the conversion but now, when I press "on" the "cruise" light dosnt even come on. :roll: I already miss using it :cry:

You're a life saver, mate. Thank you, so much. This is an incredibly detailed document. The coloured pictures make it so much easier to follow than any workshop manual, too! I really appreciate your work and have saved and printed a copy for future reference! :D

Turns out my timing chain or some other timing element failed as my cam no longer rotates when cranking the engine. So my first major mechanical job is removing my engine to diagnose/replace the failed timing components.

Wish me luck, fellas and If I need any help I will be sure to post a new thread in the appropriate forum.

I have downloaded this document but it wont open! I just want to know hoe to trick an el auto ecu into working with a manual box in an ed falcon. Ive now wasted over 2 hrs on this so just gimme a straight answer to how its done. Thanks.

I only have a mobile to view & download documents. I even used my friends high end samsung & no luck. I just want to know how to trick the ecu into working with a manual. Can someone just copy & paste the relevant info here?

VIC, Australia

--Going to try 'roughredXR6' method on this page (21) and will update as to whether or not it is the solution to my problem--

Basically I converted my EF XR6 to manual with the auto ECU and didn't do any resistor trick or anything. Just disconnected an old loom and plugged in this one (pictured) and it has worked completely fine apart from some idling issues such as it ranging from 900-1200rpm then sometimes it will sit at approx 2000RPM and wont drop back down. It started up first go etc though completely fine.

Currently installed: Image


So I recently purchased an EF XR6 manual ECU and connected that and power windows etc work but the car won't start. It attempts to for about a second and then dies. I assume this is a wiring issue of some sort and I've missed a step in the conversion guide.

This is the loom which I removed when I converted the car and has run fine (apart from slight idle issues): Image
It is currently in the shed (just took the pic a few minutes ago).

Could somebody please suggest what I am supposed to do to get the car working completely normal (like if it were a manual from factory) with my manual EF XR6 ECU and those wiring looms that I have?? Or do I need something else? Cheers!

EDIT: Auto ECU back in for now, car turned on first go like always.

you have done everything right, I would say your manual ecu is stuffed..

the only things required to make auto ecu work in manual correctly is the resistor required on the loom for trans temp, this allows the fans to operate correctly and a resistor for gear position, this tells the ecu its in neutral and this should fix up the high idle....

pretty sure all the details to this are in this thread...

If it runs fine with the auto ecu, I'd say your manual one is cactus. You couldn't have messed up the wiring just by plugging in the manual box loom.

So it either has something todo with your wiring on your windows, or its your ecu.

But you just proved that it's not your window wiring by switching back to the auto ecu.
