Build Guide - Contents for Comment
Turbo Mini Forums

Rod and I are working on a build guide for the MS/Siamese code setup.

This is not intended to be a definitive write up on fuel injection, but more about the specifics of implementing the Siamese code on a an A Series engine.

If you want to know about EFi then Dave Walkers book is recommended and there is a lot of stuff on the Megasquirt website/forums.

Anyway, the contents page is attached for comment.

Liking the look of that very much! Looking forward to seeing the Configuration Options section as there's a few things in MegaTune i'm not sure about changing for the moment.

Oh? Advantages of Tuner Studio?

Schrödinger's cat - so which one am I ???

Great stuff guys, I'm sure this will help pave the way for more people to experiment with this.

this is good stuff guys -

got to be honest - its all been lost on me up till now so hopefully it will start getting a bit more understandable!

I have to say that I am a little embarrased helping Paul with this as my own Megasquirted, Fuel injected, Turbocharged, Siamese code, A series 5 port engine.... whilst it runs fine, the furthest it has moved so far is from one end of the garage to the other and that was on a sack barrow.

But seriously, what kind of detail would you would like to see documented in one place (ie, the "manual"), as this would help us both to know what to cover.

There's masses of information in the EFI section of the forum but this is an attempt to put the key bits of the siamese code in one place.

Looks like it's going to be top notch for us that don't get everything that injection on a 5 port includes. Might I suggest something to the Main Hardware section though? Plenum sizings, the why's and whatfors of it, as that's something I just don't get. I see all these people with completely different sizes of plenum(not just mini mind you) and I'm not sure as to why, and what's been found to be most efficient on a mini/5 port.

I could be completely daft though.

I should add that this table of content looks like a good list of what is needed to get started.

As mentioned there is then the issue of tuning. And while there is a lot of information elsewhere, there is enough things specific to the siamese code to make a guide a very desirable thing. However, this is a sizable job and it still remains to be seen (at least in my view) if all engine configurations will behave the same even though the basic principles should remain the same.

Just came to me, but it might be worthwile to add a list of people that are deep in on the injection, such as Jean, his website is a phenomonal(sp?) resource.

Forgive my ignorance - I really need this guide - if it's a monkey see, monkey do type (info) guide I'm the man to proof read it!

An explanation of 'siamese code' would be a good start (I take it to mean the code written to control the injection, when fitted to a head with siamese type ports - am I right?)

No mention of MAP (manifold absolute pressure sensor isn't it - is it mentioned under another name?). Likewise Lambda sensors (oxygen sensors - the same thing?), and wideband ones at that - what is the advantages of using wideband.

ETA And I agree with the plenum comments - I understand the plenum to be 'just' a reservoir of air when used with injection.
And whats this Megatune - open source software or something for setting the hardware? (I did say I'm ignorant to all this technology stuff )

Well, there are some useful comments above and we will try an answer them in the guide.

However, I will reiterate what I said at the start of the thread. We are not going to spoon feed and wipe the arse of everyone who wants to know about fuel injecting the A Series. If that is what you want to do, then go and learn about Efi then use the guide to apply the specifics.

Paul,

Is it worth mentioning at the start the effect Siamese ports have and why a conventional EFI setup won't work? I think one of the biggest issues out there is that the majority of people don't understand the problem & if they don't understand the problem there's little change that they'll understand the solution regardless of how well you explain it.

Also is it worth mentioning plenum chambers?

Edited by Rob H on 4th Dec, 2009.

Rob, there is already a page and a half explaining the problem. Hopefully that will get the mesage across.

I'll get something about plenumbibliums in the manifold section.

+1 for the contents,
looking forward to seeing it an maybe help me understand what your usually talking about

Yes i moved to the darkside

Fantastic what you chaps have/are doing !!
Absolute admiration

It looks very good Paul,

personally I reckon you don't really need to put anything for stuff like fuel pump/ regulator/filter and wiring, as anyone taking this on should be past this level already.

I know you'll produce a top write up though!

Hi Paul,

I suppose you mean Idle air control instead of inlet air control.
A chapter on tune settings for different A-type engine builds would be nice. It would certainly make firing up the first time a bit easier

Regards Will

this almost makes me want to go back to a 5-port a-series just to contribute... genuinely appreciate the work involved gentlemen, onwards and upwards!

Guys, very interested in this guide, as I fancy having a go on this, (or more helping a mate out). Any ideas on when there will be a draft copy out? any idea what the cost will be?

Cheers
