Are there any knowledgeable people out there that know the SC Delta 400 kit?

I have one on my Mini, which was originally a carby model.

 

Has anyone had any luck setting up closed loop fuel control using a wideband sensor?

 

Or controlling an Idle Air Bypass Valve?

I have tried SC in the past regarding idle control but without much luck.  Their view being that idle control by changing ignition timing should be sufficient.

 

Any info or ideas would be greatly appreciated.

The ecu is not well regarded by anyone. Where do you live. Find the nearest Rolling road to yourself using the scs website which has a map of the trained operators for that ecu. Then take it there

Tbf i’ve managed fine without an iacv and used the ign timing for idle whilst its on cold start enrichment, used throughout winter and in the snow. When cold just needs a blip when coming to idle, no drama.

I am in Australia, very hard to find a rolling road over here that know the Delta 400 and SX Tune software.  I have had it on the rolling road a couple of times over the years with results being pretty average.   More popular ECU's are the Emerald and then the Haltech if you have more cash.  Thus I am keen to understand if the closed loop fuel control is functional on the Delta 400.

We are happy with the idle control as it is, just curious if IACV is an option.

The only 1 in the whole of Oz that SCS recommend....
Hope you're near Port Macquarie

I understand Haltec is more expensive but like Fueltech infinitely more tuneable.

 

Once i finally get my 7 Port 1293 in my car and running i will be upgrading to a Fueltech ecu. And like IronmanG has said the Delta ecu is not the best. We both had 7 port engines built for us by Ian Oz Osbourne, mine is the Billet Aluminium SC 7 Port with their Billet throttle bodies whereas IronmanG had the cast SC 7 port head with ITB's. Both very similar builds. And although i was happy with the final results i feel the ECU is holding things back, however time will tell.

Youve not mentioned if you have a wideband lambda installed into the system or not. If its a narrow band, you can kinda get it to work, but it wont be a great way to tune it, or use closed loop to its true benefit.

Yes, it is a wideband with the lambda data available in the ECU.  Data looks good in the scope and gauges.

I will try and set up the target lambda table and give the closed loop control a go.  Would be good to know if someone has had this working successfully with the Delta 400.

It might be worth reaching out to Graham Nuske, President of the SA Moke Club. He's not a tuner, but he has this set up on one of his Mokes, someone local to you set it up for him.
