Money spent better elsewhere.
Someone else can confirm, but wasn't the exhaust system what added the power over the fairmonts?

I would love to know more about this. Just discovered that the ECU I bought off eBay a while back is actually from a EF series one Fairmont Ghia auto Tickford 4.0i - catch code on the ECU is 4TBD.
I had been under the impression it was an XR6 ECU. So now I want to know what the difference is between a Tickford Fairmont Ghia and an XR6 (mechanically speaking). Also, is there any difference as far as the ECU is concerned, if the car is manufactured with a particular diff ratio? For example, would a different ECU have been fitted to a car with 3.45 gears, compared to one with 3.08's (assuming all else is equal)?

Series 1 EF Ghias were not Tickford optioned, you will need a ECU from a series 2 EF Ghia.

Catch code still indicates that it is Tickford optioned, so it must be a series II then...

If you add the Tickford 300kpa fuel pressure reg, as well as improving the air intake, and a sports exhaust system, including extractors, you will notice seat of the pants improvements. In addition to improved fuel and spark maps, you also get better auto mapping and control. The auto feels much more lively, will kick down more readily, and also has a firmer change when you are giving it a bit. The auto mapping is set up for a 3.45 diff, but works fine with the 3.23 which will be in the Fairmont. If you can get one for a good price, there is no reason NOT to do it, but spending a few bucks on the ECU alone without the other mods, is a waste. Cheers BenJ

I agree completely with that BenJ has said above as that is exactly what i have found with mine. I have a Series 1 EF Fairmont. I picked up a Tickford-spec ECU out of a Series 2 EF Fairmont Ghia (5DCA) from Pick a Part for cheap and fitted it along with the 300kpa fuel reg which i also pulled out of it. The car also had upgraded intake, extractors, sports exhaust and a mild cam at the time of fitting and i can honestly say it does make a bit of difference.
Straight away i could tell it pulled better through-out the midrange, not a huge difference but it was noticeable. As BenJ also said, it has better auto mapping. On mine it changed the shift points a bit, but it suited my driving style better, and the shifts were a bit more firmer than standard. I think the main difference i noticed with the shift points was it would hold 2nd gear just that little bit longer than the standard ecu, especially noticeable at quarter throttle which was good as i usually like to pick up speed in 2nd. Well worth the $60 odd i paid for both the ECU and fuel reg IMO |

Thanx guys i'll have to have a look at the code on the ecu and check out the fuel reg and the plans were full exhaust system and a custom 3inch stainless intake (with ss inductions snorkle?) to start with and go from there.. Cheers for all your help guys will keep you posted

Thanks again guys all help much appreciated Cheers Darcy |

Just stick with the 5DCA one you have

After a bit of hunting around I've come to the conclusion that my 4TBD is XR6, not Ghia - maybe I'm wrong but I'm yet to see a Fairmont with "B" in the third digit of the code. Additionally, since I've now learned that the series II Ghia (not series I) had the Tickford optioned motor, I'd expect most series II ECU's would start with a "5"...

What diff ration does an EF Series One Fairmont Ghia have? 3.23 or 3.45? Also if you fitted an XR6 ecu to a Farimont would you not loose some of the Fairmont Controls, speed sensor steering, climate control fan speed reduces with WOT, thats the only 2 I can think of atm.
