after market common rail diesel ecu

[Northside 4x4]

Factory ECU better than a good Motec.... hmmmm.......i'm sure the touring car guys will all be lining up to pull theirs out and put factory back in.....
However a good tune on a factory ECU is better than a badly tuned aftermarket unit... but as for sheer processing power aftermarket ECU's like the Bosch or Motec have the grunt.

Factory ecu would dominate just about any aftermarket for processing power.

The downside is, lackluster logging ability. And thats what all the race classes need.
I think you would be surprised to know just how many of the circuit and rally cars now run standard ecu's with ecutek tunes rather than full aftermarket though.

IMO regardless of the ecu, on a diesel or petrol or methanol burning motor.it has this much air, You fire in this much fuel at this point, ignite it at this point (on petty motors) and you will make the same power regardless of the chosen method of control.

Well on the ECU front - we'll just have to agree to disagree.

As per brute power - your also spot on the money, the old continuous flow mechanical systems proove that brute power can be quite "simply" achived.
However, if you've ever tried to make one idle nicely and drive around town, you'll appreciate that much of the sophistication in ECU technology brings tractibility not absolute power.

This has significant benifits for the overall performance of the vehicle.... a medium power tractable vehicle will in most situations be far quicker then a cantannkerous "grunter"

That's were the ability to include modifiers into the strategy really shines... the Bosch racing ECU's are a good example of the sophistication and tractability possible when the engines
performance is correctly modeled ( not mapped btw....).

Well on the ECU front - we'll just have to agree to disagree.

The motec option is a "future development" anyway isn't it? So, the point is moot. Of the available options it sounds to me like a tweaked factory unit is the only realistic way to go.

I had a pair of garret turbos custom made for me for my 454 BBC, t4 83ar rear housing 60ar front with a 60trim with custom 3 inch cast iron dumb suit v band with clamps, flanges etc, by a mob in canada last yr delievered to my door for around $1300 I would use them again in a flash.

If they are in Canada, the only VNT they'll know about is the VW TDi's. I think Europe is the only place to find that expertise, with the bonus that they have used cores to build turbos from. The prices in europe are a bargain if you're earning Euro or Sterling.

I thought na they rock what are you talking about so I jumped on there website and yep only one rebuilt VW VNT oh well I tried.

My vote is run the mazda ECU. As long as you have all the required bits then there is no reason why it can't run. At most i would think you would need is engine ECU, BCM, maybe cluster. The CAN bus may pass through the other modules, but that doesn't mean we can't bypass them.
Security immobiliser system would need to be wired in aswell.

As long as we can get good wiring diagrams for it (should not be a prob), I would be willing to give it a crack. I would need the vehicle here (1/2hr south of Gympie), And would not want to be put on a deadline, saying that it won't sit here for months and months. I specialise in custom work, Not scared of a challenge. Can't be to much harder than the Duramax.
Give me a call during the week if you want to go this way

The disadvantage to running aftermarket is you will not get the maps as good as factory without spending huge hours on dyno.

You are not going to get a better offer than this.

On another front to all watching not this weekend but probably the next I am going to put all the wiring harness back together as best I can and plug every thing onto engine.

The engine is still in the chassis rails to keep it rolling, so I will use a bit of white malimine and throw harness over it then try an spread it all out marking what I know disconecting what I know doesnt need be there and rejoining what does I will go as far as I can.

I have spoken to steve and he is happy to help, but needs it all there naturaly of course, so hence above to help keep hours down, and help with transporting etc. so I will keep this updated as it progresses.

To any one following this I have deemed it overkill for what I wanted to acheive so I am selling it on ebay grab a bargin.

thats a shame i just read the whole thread to find out its not gonna happen, woulda been a very interesting journey...

cheers, andy

[offroader-rama]

yes its a shame I was very excited but it come down to two factor

1. over kill in hi tech and expence for a 4x4 that maybe drowned first run ??.

2. neighborhood dispute making working on cars at home, very difficult meaning trailering it to mates house every time i wanted to do more work.

so i am selling heaps of sh!t off and thinking of moving as a bigger importance.
