Bought one of these literally decades ago.
Any good on a turbo?
If it's going to be difficult to tune the SU needle I might just go injection...

Why do you think injection will be easy to tune?I have two non mini injected classics and tuning is quite involved.No criticism just experience(I may just be a useless tuner)Steve..
I guess it depends on the injection system.
My assumption is that there's plenty of expertise out there among dyno operators in tuning aftermarket electronic fuel injection (running wet manifold not siamese injection). Something more mechanical like Bosck K-jetronic would be a different story.

For a classic mini with a bit of boost, I'd say the HIF44 would be the most widely used. There should be plenty of experienced tuners that can help you out

Lots over on TurboMinis have gone over to injection, but also with 7 port heads. Familiarity with the software won't be the only issue, not many will have experience of injected siamese ports.

ECU is essentially dumb,until you tell it what it has and what you expect it to do it does nothing.If you tell it to do something stupid it will just go ahead and do it.It seems that setting timing with a dissy is difficult,missing tooth,timing offset etc is challenging in a different direction.When fitting ECU the first thing to do is verify the timing is what you think it is.Too many think it is not needed and "I skipped that part".Wrongly set injectors squirt litres of fuel in minutes and incorrect timing can cause fires(I set one of my cars on fire)
Tuning;the best dyno can only tune cranking pulse and warmup from cold,so maybe once per day.I tuned my car in the summer,when winter arrived it looked up the cranking pulse and had no value as it had never been cold enough so it used the last summer setting resulting in not starting.
Seeing the picture?I suggest it is very interesting and rewarding but you need to have access to the tuning software and be able to use it.
If you are interested I think it is the way to go.Sorry to drone on,Steve..

Yes, I get the picture - I'm an ex automotive engineer.

I have a Siamese port 1800 MGB running Megasquirt for the last 20 years or so(used this because it was ridiculously cheap at the time and it was sold as "experimental" It certainly was with next to no instructions or support.Steve..
Hi Steve, that's really interesting - does it run ok?
I think the user interface software has come on a lot in the last 20 years.
