xf computer wont run a zk fairlane (i had the same idea) coz of the different fuel types that they needed to be tuned for when they had to make cars for unleaded.
i have also been told that the xf computer will use more sensors too - might explain why the zf efi seems to run better than xe / zk efi systems

hi

worth having a look into that set up converting from a airflow meter to a map semsor set up

a bit of work involved but im sure the eec-4 EA would control the engine better than the older eec-4 havent heard of anyone doing it but would be nice to see how it works

speciallly with all the idle problems associated with the airflow meter eec4's models ( ie just lift the dipstick out of the tube while the motor is running it idles s**t and same as the oil filler cap just undo it slughtley it idles like crap and im sure all the seals on the engine are getting a liyyel hard :wink: )

and if you need any wiring diagrams there are some in this forum and ifyou cant find them i can send you some im sure you could get all the required parts from a wrecker ie all the sensors and ECU and some of the wiring loom that u need for the connectors.

the fuel system can basically stay the same ( ea multipiont injected version and the zk efi have the same fuel pressures so fuel system can stay the same )

have fun

cya

If you are going to try this, then don't use the XF bits unless you want keep running on 'leaded'

The XF system is almost as bad the XE, it is open loop so does not adjust the fuel very well because it has no O2 sensor. You would be much better off trying to adapt an EA/EB system, but unless you are good on the tools and the electrics it you will need to pay someone else a lot of money to do it.

I was going down the EA road, but have now opted for Megasquirt. (work in progress)

hi

yes megasquirt is a good option but once again he needs to pay someone to tune it for him

where the eec-4 out of the ea or eb falcon would work straight of if wired up properly and cost next to nothing oif he purchased the whole lot from a wrecker ie all sensors wiring loom and ecu

keep us posted how you go with your megasquir
which megasquirt did u buy 1 or 2

Lets play spanners!.

The XF had the same crap air system as the XE, but it had a knock sensor. if your using it, then thats all good. if not, its a waste.

The EA one would work ok, but Id go the later EB pre 6/92 one so you get later code. TPS should bolt up. you'll need to change the IAC setup over (most likely easiest way is to use the EF item with TPS on the top of the throttle body). If you go with the EA/B Setup, just grab the entire engine bay harness from an EA, B, or D and the Engine harness as well.


In fact, now I think about it, your making so many changes youd probably have a lot of fun with Kalmaker. Use a Holden ECU, IAC, etc etc. And program it yourself. You can get so much from them.

Cheers

hi

kalmaker is great holden tuning software

kalmaker software is expensive whether u buy street pro or the fullon workshop version

and you still have to buy all the commadore sensors and ECU

I think the guy just wants a a reliable Engine managment system that will just run a stand early EFI 4.1lt ford engine which a later model EEV-4 will do fine

Question do u have kalmaker and what version ??
have you ever fitted it to a ford ??
what success have you had if YES ??
who did you buy kalmaker from ??

cya

Why go to all the expense of a Kalmaker?

http://www-personal.monash.edu.au/~ish/fleet/mods/mods.htm

I still think the EA/EB option would be easier though.....

to answer your question for the time and mucking about i dont reckon there would enough improvement to worry about it. i reckon either stick with that engine or if you are gonna keep the car and can afford some time and money then drop a newer six or eight in it or run a carby v8...

carby v8 in that thing would be easy and nice to drive.
