help, taking the efi way
Turbo Mini Forums

Well that's a while this is in my head,
ditched the turbo yersterday....
so I'm putting an lcb on, with twin inlet entry a la hs4,
then it will run like this untill I have all the parts to put efi together,
I already have two wbo2, and the nut to weld on the lcb for inner and outer mixture reading, trigger wheel, and mpi camshaft with sensor.
then which megasuirt to use, and where's best place to buy it,

You should know that I'm not that easy with all this stuff, and if somes are giving me a good english, I've a lot of nightmare to fully handle what's generally been writen. So HELP!

I understand that Jean is the goodguy, and that some already trying his code,

I would like to pass on the hassle of soldering etc , ideally I would like a complete assembled/tested megasquirt with the code inside,it'll save me a lot of time that I could take to concentrate on injector positionning,runner lenght, welding, timing..
knowing that along with this I'm trying to weld the raised port head..
though please,
fabrice

Fab,

I suggest you talk to this guy:

You should be able to use a realtively simple MS2 without the need for staged injection if you are not using the turbo.

You will proably need a VR conditioning circuit for the MPi cam sensor.

hI Paul, I've just ditched the turbo to set up efi.
but then the turbo will go again with a new manifold and turbo

In that case you will need the MS built to incorporate either Jean's P&H board for low Z injectors, or the Quad driver board for high Z injectors.

If you speak to EFIExtra they should be able to put one together for you.

You will also need to decide on spark. Wasted spark coils is easy, but you will need some extra circuits if you wish to use COP.

Welcolme on board Fabrice,

It will be helpful for someone else to be going down this route.


From your first post, I assume you will be building your own injection manifold ??? It will be interesting to see how you design it, ie, any different ideas.

Shopping list as Paul says, but you will hve to learn how to re-load the code eventually as Jean has revised it a couple of times already......

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

manifold wil be a simple tube taking motorbike itb, that's why I woul like to build the raised port head, then if I I've trouble with the efi , it will only be a sawp for the set of cvk40

Would I need to run the same setup as you turbo guys if I was looking to run a suck through supercharger using two MPI injectors mounted in the opening to the charger similar to the vmax setup?

no, suckthrough is easier EFI wise. That would be like an electronic carburettor so to speak

No, not if you mean the Megasquirt with siamese code.

This system is for port injection to be able to allow different amounts of fuel to go to inner and outer cylinders.

Once you put the injectors before the charger (or a throttle body or anything else that far away from the valves) the mixture gets all mixed up long before it reaches the ports so you are effectively running a SPI or wet manifold (or electronic carb) - the siamese code would offer no advantage over a normal Megasquirt or any other EMS.

Fabrice,

Si tu as besoin d'aide en français pour certains aspects, je devrais être en mesure de te donner un coup de main (mais peut-être avec un accent québécois :) ).

Mais comme le mentionnait Rod, tu devras éventuellement te familiariser avec le Megasquirt ne serait-ce que pour charger une nouvelle version du code. Sinon, ça deviendra vite frustrant.

That reminds me that as well as get the Turbo on the 998 within the next three weeks, I also need to listen to my Teach Yourself French CDs before I head off to the Med

I like the bit about the Quebec accent..... in written french ?????

Mind you, I suppose we do different "dialects" in written english too.

That's why I put the smiley. But we do have quite different expressions and even use different words for certain things. And the funny thing is that we both use English words (anglicismes) but often not the same.

And I'm so used to writing and reading on everything related to engines and EFI in English that I either don't remember the French term or don't even know it. And that's assuming that the French terms used here are the same as in France (kind of like the different words used in the US and UK).

oh Jean!
a french speaker that's marvellous...
do you know which of your words sens is the best here?

Franglais will do !!
