 Posted: Tue Jun 17, 2008 7:16 pm Post subject: Which ECU to get? |
 |
|
| Today i rang a wrecker i know and asked for price and availabilities for various parts. One of these was an EL 6cyl auto ECU, but i was told there are about 20 different types of these, which do i want? Indeed, which do i want, or doesn't it matter? I am putting an AU motor into an EBII GLi auto non-smartlock. |

ummm I am assuming you'll be running the distributor rather then coil pack. I'll imagine an EL XR ECU would go down well if you got the XR accessories strapped to the motor. If you don't I'd say any would do fine.

AUs run a coilpack though dont they?
probably use and EF/AU ecu. |

Yeah they do, but I think you swap it over for a distributor...unless I am thinking off EF motors.

yea you can just drop a dizzy in a au engine and use a el ecu..
thats the easiest way to run a au engine in a eb .ect.
it doesnt really matter about the ecu.. as long as its a 60 pin el ecu.
there are a few differences in them but they will still do the job.
if you can source a tickford ecu it would be slightly better but a std one will do.. |

Yes, i'll be using a dizzy.
By tickford you mean XR6? Why would one of these be better than a std one? Because both the XR6 and the AU have higher compression than the std motor? |

| hi champ ill have my hands on an el ecu out of a fairmont ghia auto which runs the el xr6 engine and a fuel reg to suit which is the 300kp if your intrested come monday..... |

Is that 60 pin, as Troyman mentioned?
I was figuring on using the AU fuel pressure reg that i expect will come on my AU motor . . . is that comparable to the EL fairmont reg? |

yhe thats right i actually have to el ecu's on from the fairmont ghia which runs the xr6 motor and a standard one that was out of a fairmont both 69 pin |

| Will you be running the AU manifold and accessories or are going to replace them with your log manifold from your EB engine. If you use the EL ecu you will have to obtain a smart lock bypass, run extra wires for the manifold runners and control the thermo fans somehow. You will also have to tweak your EB engine loom to suit the AU motor. |

I will be doing the latter, bbm etc. For details refer below (scroll to the updated list):
http://www.fordmods.com/forums/rd-s-ebii-engine-upgrade-t65892.html
One question on my mind is where to run the wires from the ECU into the engine bay. I looked around the other day and it seems i might have to dismantle parts of the dashboard . . . ugh? (at 6'5" with broad shoulders dashboard work is an extra b**ch, but i could remove a front seat). Any suggestions? |

i think its a miss type..
el ecu is 60 pin like ea/eb/ed.
and ef is 100 pin like au... |

Thanks.
Jumping back to a question i asked, do you mind giving your thoughts on the following;
"By tickford you mean XR6? Why would one of these be better than a std one? Because both the EL XR6 and the std AU have higher compression than the std EL motor?"

| its the timing and fuel maps in the ecu that make the tickford xr6 ecu different to suit the xr6 cam.. also the auto gear shift is slightly different.. |

So the EL XR6 cam is more similar to the std AU cam than the std EL cam?
| Quote: | | . . also the auto gear shift is slightly different.. |
I like later upshifts and earlier downshifts, but prefer stock shift speed. Not fussed though unless the difference is big, then i would want to investigate. |

actually the au xr6 cam is similar to the e series xr6 cam.
but the std au cam is a bit different to the others.
here are some of the specs..
the std au cam
intake opens @6 deg btdc
intake closes @64 deg abdc
exhaust opens @66 deg bbdc
exhaust closes @18 deg atdc..
the std 4.o cam
intake opens @16 deg btdc
intake closes @63 deg abdc
exhaust opens @62 deg bbdc
exhaust closes @14 deg atdc
the au xr6.
intake opens @14 deg btdc
intake closes @68 deg abdc
exhaust opens @56 deg bbdc
exhaust closes @24 deg atdc..
the e series xr6 cam.
intake opens @14 deg btdc
intake closes @66 deg abdc
exhaust opens @62 deg bbdc
exhaust closes @18 deg atdc |

From that the std AU cam is more similar to the e-series XR6 cam than the std e-series cam. So in that respect i might be better to go for an EL fairmont ECU or EL XR6 ECU, as you say.
But what about the other factors? My main priority is maximum fuel efficiency. No pinging problems is nice and part of that (but i'm mainly running LPG, so its not quite as important as it would be otherwise). Other than that normal smooth auto gearshifting is my preference. Earlier downshifts and later upshifts would be nice due to the big wheels effect on the final drive ratio. |

I have received the following information. It seems good info to me.
| Quote: | Only the EF series II Fairmont Ghia and the EL Fairmont Ghia had the XR6 engine and ECU equivalent.
You need the EL Fairmont Ghia ECU . . . If you can get one do it. I have one in the EB running the EL engine. Otherwise, any EL Auto ECU will do the job. |
It also seems pertinent to consider the final drive ratio and character of the donor vehicle, as the shift points will(?) be chosen by ford in some relation to that. I am told the EL fairmont uses 3.23 and the EL GLi uses 3.08.

And the EL Fairmont Ghia uses the 3.45 diff.
When I had the 3.27 gears and the EL Ghia Tickford ECU, the auto maps worked ok. They were a little out of synch at times, only really noticeable to the really picky when slowing down to a stop.
The Tickford ECU will kickdown more readily and will rev out further, as well as providing more midrange punch. Mind you I have a modded intake, Paccies, highflow cat and 2.5" mandrel bent exhaust.
