Siamese Code Trial - Take Three
Turbo Mini Forums

Great stuff Paul!!

looks like youve really cracked it.

i really need to re read all this stuff to geat my head around it, but top effort :)

Well done Paul.

That's a great deal of effort gone into proving an aftermarket solution for fuel injecting the five port A series.

Your huge investment in time and equipment has finally paid off.

Time to get it fitted to the Miglia to just show what's possible.

Thanks also to Jean for the code development that made all this possible.

All Clever stuff, you lost me on page1, but I roughly understand the problems and the results look good! Well done!! I'll buy you a pint when I see you.

You guys obviosuly tried harder in school than I did.

Paul, what's your day job?

gosh thats a bit of an improvement ,will you try single pulse and two inj per inlet in parallel or is that whrere you are now ?

Medusa + injection = too much torque for the dyno ..https://youtu.be/qg5o0_tJxYM

no your right , i think fitting the turbo will be easy . hopeb youv got those 888's on order .

Sounds like you cracked it! Nice work, whats it like to drive compared to an SU?

And does it sound different? I imagine that with the manifold and TB it must be quite different from the SU's sound.

More refined if anything.

when will you start taking orders? I'm interested!

Taking orders? This is Turbominis not a take-away...

You can buy and build a kit and do this same stuff...

Well done Paul ! Ive been reading this thread with great interest in the last few weeks and the progress has been phenomenal ! Top work and congrats to all the people involved in the R&D !

I'd agree with that, revs easily right through to the rev limiter, it just keeps on pulling

I've had a bit of a play with the settings this afternoon as work is a bit quieter.

We had been having a bit of a stumble just off idle. It had a tendency to miss if you stamped the throttle.

I thought that it was injection timing or VE related but could not cure it by adjusting the settings. I also thought it could be the 55mm throttle body which is a big on the large side.

It turns out that the Acceleration Enrichment was bringing in the second pulse and dumping extra fuel into the inner cylinders when it was not needed.

I've taken out the AE all together and it is much better, although it feels as if it does need some enrichment.

Ultimately, the real solution is going to be fully sequential with Jean's add-on board driving four injectors separately.

have you checked the megasquirt logs for erroneous engine bits due to electrical noise?

I'll have to have a look at this and see if it can be corrected. But the best solution would be to have a single pulse mode and potentially a switch over point where it goes from 2 pulse mode to one pulse mode with some hysteresis.

also paul it may be wort trying a damper in the map line, made quite a differance to the drivability of mine. in fact i'd wager andywaller could actually pull away without stalling it now! lol

wow! im away for a week and alot has changed!!!!

congrats on the progress! look forwards to seeing the turbo-injected miglia at avon....pull you finger out!

I actually do some real work occasionally, but only to pay for my addictions.
