Hello all,

A quick question, basically to run a Mitsubishi Magna in a class of speedway it is required to be using the following rules:

"Engine to be used is a 6G74, 3.5lt, multivalve – single cam
per head. Must use an approved Falcon computer and the airflow meter maybe replaced with the
Falcon map sensor to suit the computer."

Now, can anyone tell me if they believe this possible? And how much would possibly be involved in getting it to work? (keep in mind this is purely for speedway racing, so no need for any electronics etc).

Is it merely a matter of hooking the gear up and making the change or would there be a lot of stuffing around? The ECU has to REMAIN STANDARD (from the Falcon, so basically it could be given to another falcon and still operate correctly).

The reason for this is the computers are sealed and at title events, can be replaced by a steward with another sealed computer to make sure the computer is standard and within the rules.

Edit: To clarify the falcon computer to be used must come from an EA/EB falcon

Cheers

I dont know how on earth that would ever work. If the ECU is to be untouched, even the most basic functions such as fuel and throttle maps would be (i imagine) completely different between the two cars, let alone the fact that magna is a V6 and falcon is a straight 6. How would a falcon ECU know what to do when trying to control a dual bank engine when its been designed and coded for a single SOHC I6.

If there is someway that this works, i am completely intrigued

As long as the ECU fuel and ignition map can be reprogrammed, it can be made to work. The sensors from the 6G74 which need to be compatible are Crank sensor, and dizzy hall effect (cam position) sensor. The MAP sensor from a ford could be plumbed in behind the throttle plate to measure manifold pressure.

The EA/EB ECU is the Ford EEC-IV system which was actually quite powerful and flexible - it was specifically designed to work in a wide range of engines.

Stolen from the "Old Fuel Injection Website", it says:

EEC-IV has been Ford’s computer of choice with enthusiasts for years. Its advanced programming can run almost any engine, while not being over complex. All the necessary engine controls are just as advanced as the newest vehicles coming out.

Here's a flash tuning kit for the EB ECU from CAPA: http://www.capa.com.au/ford_flash_tuner_eliminator.htm

Hello Kaldek cheers for your response, Looking at the rules (as posted by Savage in the post below) I don't believe it allows for reprogramming of the ECU as this would not allow the computers to be interchangeable at a title event, the computers are also required to be sent away and sealed, so once sealed would I be able to adjust the the fuel and ignition mapping?

As stated in the Street Stock clarification rules:
"Computers – S.S.A. reserve the right to exchange sealed and tested computer supplied by Automotive
Service Solutions at any time during a race meeting."

The problem is I don't believe there are currently any street stock magnas post 1996 in the country at the moment, the only late model magna I have heard about is running in Vic as a modified and that would be a completely different setup with different rules allowing for different computers etc. I believe with the Magnas power to weight, FWD etc it could be made to be very competitive, just getting it started and built and running will be the main hassle (handling will be the other drama once racing!).

To be honest knowing how the eeciv runs and the magna, can not be done.

Putting aside the fuel, firing order is wrong and inputs required will be missing or not compatable

Well if the ECU can't be reprogrammed and the sensors aren't compatible that really puts the kibosh on the idea.

Looks like someone has asked the Magna question and this is their throwaway response. The next couple of pages let commodores use Holden ECUs, so why can't the Magna use a Mitsubishi ECU? Smacks of "we can't be bothered investigating this".

Check table 6 it says you can use a magna ECU a TF one Magna 0580453477 :)

It would be a lot more to do with the fact they wouldn't care spare standard Magna ECU's with them to titles, so I could easily run a Magna ECU that has been changed (even though they are sealed??) and they couldn't prove it wasnt standard.

Could easily be gotten around by requiring me to provide a standard one to the stewards to allow them to seal it prior to the event, then hand to me on the day (if it was a state or national title) but at a local event it could go uncontrolled etc...

Will have to get in contact with someone from the ASCF and find out if anyone has even attempted it, or if that is a sly way of stopping them running.

I think thats the part Number of a TF magna's fuel injector? the ECU part number is "AW 342757"

The other thing is, all through that document it talks about the TF magna, which didn't come out with a 3.5l V6, only the 3L V6? So effectively they are saying you can run a TF with a later model engine. So I am guessing that someone messed up along the way/application process and got the wrong model.

Looks like they have no idea on Mitsubishi cars at all lol So point out there faults or just use a TJ computer and a 3.5L motor :D

Oh no speedyway and efi, they are so scared because they have completely no idea. Get some factory Part # for the 3.5, plead your chase thats your best chance.

Remember they don't understand ecu's and when you say 4 valves per cylinder they think Offenhauser/Ford BD series, which are very good but very expensive.

In life there is Right way, Wrong way and there is Speedway. Don't bash me, I love to watch it but the politics arrrh.

Good luck. Cheers Dave

Well I have emailed the state secretary who has passed it onto the technical committee so I am awaiting a response on the reasons behind using the Falcon computer, could explain why noone else has completed and running a Magna at the moment. I mean half the trouble is just finding a TH onwards Manual Magna to be used to race in the first place!! But I won't bother going through all that if I am not going to be certain it can work without its own computer.

Well for anyone playing at home and interested I have received a response.

Basically someone has made a submission from Victoria to run a 1999 Model magna with the 3.5l engine (so a TH).

The reasons for not allowing the Magna computer are that it is a programmable computer which is outside the current specs, but the falcon computer is approved so the person with the submission requested this. He apparently is currently racing and I am to be forwarded his contact details as he is happy to help anyone wanting to try, with the wiring harness and setup etc. So in a nutshell it seems it is possible and I will hopefully find out shortly how, and if it will be worthwhile or if I just stick with the norm and run a falcon or commodore.

Cheers for everyones help thus far.

Keep us updated as i am intrigued on how an unfettled falcon ECU can be used in a magna

maybe he is running a magna ecu and has the falcon computer plugged into a dodgy, unconnected piece of loom >_>

Your kidding!! what bullshit. So they are saying you can't reprogamme a Fal/co, door ecu. sounds like it's all to hard so it's a closed shop just like V8 stupidcars.

Good luck, it's a way better engine the other 2 shit boxes.

Cheers Dave

Wireless ECU LOL

buy a sealed falcon unit run the loom from the ECU into the the existing hidden magna ECU bam!!! cheating but who cares 99% of them run a XR6 EF ecu hidden anyway so who cares

Also,

Just a quick question, since finding a 98 onwards MANUAL magna is nigh on impossible (for around the $500-$1000 mark which is all I want to max pay for it, (ie: since no need interior, can be panel damage etc), is it easy enough to fit a manual box to say a TH or TJ 3.5l auto?

Can the manual box out of a TE or TF be used and what are the advantages/disadvantages of this?

As there seems to be a few around for the $500 price range, just rare to see/find one with that price and being the 6G74 motor :(
