Excellente post!!!!!!

Do you have an idae how much boost can the map sensor measure??

[Asad]

Okay lads! Here it is!


Sitting in case everything done!:-




This side will connect to engine loom, and you can see the MAP sensor inlet:-




This side has the laptop/pc connector. The LEDs are Injector firing, Fast Idle and Acceleration Adjustment :-




Case cover is on and all sealed up! :-



Running, you can make out the fast idle LED. LEDs on right hand side are from the stim :-



With Flash :-




This is the tuning interface on the program. You can see the 3D map :-




And the realtime out of each sensor (from stim at the moment):-




Phew! Easy part is over, now begins learning how to tune!

First though, i need to decide which direction to take with the loom. Use my existing 8v? Get 16V external EDIS?

Oh, and the MAP sensor can take up to 2.5 Bar

thats some gooood s**t man! let us know how the tuning goes v.interesting

[FezzR]

cool progess is dam quick, new toy and justed wanted it all to be working and play with it by any chance?

as for what im doin, hopefully ill be able to map a EEC-IV ecu before the end of the summer initially it will be a quite a lot of hard work hours and head scratching, but at the end of it all im hoping it will be as easy to map as megasquirt but with all the quality and intelagance of the EEC-IV

as for your loom not sure what setup your running, but the standard loom and just connect were the stadard ecu would, and yes i think you can safely say ull need an external EDIS

oh and if you know anyone with a similar spec engine with megasquirt your prob best asking to copy there map at least then you'll have a running engine to work around

[Andy.B]

Mark XR40 has a 2.0 running on mega squirt, ask him for his base map, at least it will get you running.

Thanks for all the comments.


Good luck on programming the FORD ECU.


With regards to my loom, i just want the best course of attack. Im currently running 8V loom. I could use this, but would have to add sensors such as CPS and HEGO sensor.

Or I could get a 16V external EDIS loom, mate it to my car loom and use that. I think this is the best option and allows me to use all sensors that I need.

I have a 16V si loom and 2.0L DEEP ecu here in my room, but I dont need it anymore as the loom is not compatible with Megasquirt!


I've already asked someone for their map, but I will contact XR40


I will hopefully source the loom and install it next week. Planning on getting it running on 16V loom and 1.8 ECU first to make sure loom is okay. Then I will fit the megasquirt!

In the meantime, I will be reading all there is to know about tuning the damn thing!

[FezzR]

good plan, very good to get it running on standard parts first, as if there is a problem it'll be easier to trace

[SimonT]

wicked :D:D:D

Can you not mount the map sensor remotely? IE not on the board?

[FezzR]

no reason why not but you'd need a housing and run wires,
saying that i see absolutely no reason why you'd want to do that, when you can just run the vacuum hose to the ecu

[Asad]

Hi

Yeah you could mount it externally, but no real reason to.

I was actually thinking of using the ford map sensor, but would probably require reprogramming of the chip etc.

Maybe later!

Asad

just need to know the respective voltage / resistance for a given pressure, whic could be adjusted with a resistor in most cases

[Zetecfiesta]

jesus your a quick worker!

[PaulC]

Asad - Any chance you can measure the PCB? Cheers

[Asad]

Its a lot smaller than you think!

15.2cm by 10.2cm.
With a ruler!

What you got planned eh?


Asad

[mike_wall15]

Asad - So what you're saying above is that the Megasquirt won't work on an Si 16V loom?



You're a fast mover by the way, well done!

[Asad]

Yeah looks that way.

The 16v SI has EDIS built into the ECU I believe.

You can modify Megasquirt to work with EDIS but it has to be external. Im trying to get a XR2i 16v Loom to run with this.

You *might* be able to piggyback the Megasquirt off the standard ECU, but i can imagine there would be a load of work associated with that.

[PaulC]

Nothing yet, just getting some ideas

[Asad]

sounds interesting......


Bit of an update:-

After going through the wiring diagrams, it seems the only extra bit I need is 1 wire from the HEGO to a relay. This means I dont need to hunt down a 16v loom, and I can save myself some hassle trying to mate it to my 8V car loom!

Plans-

Modify my Megasquirt to control EDIS. Just a bit of re-soldering required.
Run a wire from HEGO (Lambda sensor) to relay.


Will try and modify the Megasquirt this week and fit the wire over the weekend. I still need to get a dud 8v ecu so I can use the socket etc.



Asad

[andyhardy]

Great progress mate!

Surely you can find an 8v with ECU at the scrappy - take the connector out while you're there and say thanks very much on the way out!

Good progress mate - what changes are you having to make to allow it to run your EDIS setup?

I never really understood the whole internal/external EDIS thing - care to elaborate on what the differences are?

Cheers,

Andy

Andy, its quite simple... the External EDIS is the module mounted on the bulkhead which is connected to the ECU and other bits via the loom. Internal is where the module is inside the ECU and therefore the loom is different as the CPS goes back to the ECU, etc.

[FezzR]

that controls the ignition timing, and rev counter signals

[Asad]

Megasquirt in its standard form only controls fuel injection. I will be modding it to control ignition too, namely the EDIS.

Hence the need for an external EDIS. This mod also allows other functions such as water injection control, Boost control, NOS control, shift lights etc.

The new Megasquirt V3 (I have ver 2.2) will have a built in ignition controller, so even EDIS could be done away with.

I can upgrade to the newer chip with a daughter board, but will see if I need to. Thats the beauty of this ECU, you can chop and change and upgrade with little hassle!


Asad

[PaulC]

According to americanv8engines.co.uk there MS kit comes with v3.0 as standard... or do you mean the v3 PCB?

[MotorcyclesFish]

Thats the beauty of this ECU, you can chop and change and upgrade with little hassle!

I think you mean "with a little hacksaw"...

yeah sorry, typo on my part! lol


v3 is the software loaded on the chip. My PCB is ver 2.2 Ver 3 is in development but not out yet.

Megasquirt II has been made :- http://www.megasquirt.info/ms2/

has some more features like programmable ignition retard etc, but I dont think there is much there that I need.

Too be honest with you, there is a whole load out there, and Im just trying to keep it simple! dont want my brain to explode!


Asad

[andyhardy]

Ahh - so the EDIS module on Dizzyless cars (i.e. coil per cylinder) use the EDIS module as the equivalent of an ignition amplifier module!

Gotcha!

I thought it was going to be something like that - just all the internal/external things had me wondering what the difference is.

So are all EEC-IV EDIS equipped cars external or internal EDIS? I'm pretty sure my FRST had an external EDIS module, as did my Mondeo Duratec V6 - I could be wrong though!

Cheers,

Andy

[FezzR]

(i.e. coil per cylinder)

not necesarly (sp)

[andyhardy]

(i.e. coil per cylinder)

OK - so some of them run less than one coil per cylinder then? I though the whole point of EDIS was that you got a fantastic spark under all conditions?

[FezzR]

the main benifit is that it does away with the mechanical distributor, with its many downfalls

as for the number of coils im not 100% certiain, when i posted the above reply i was thinking coil on plug or 4 individual coils, but the above still stands,

i have a feeling most single coil pack arrangements either use one or two sets of coils, ( never really checked)

coil pack being generic term for module containing the coils, remembering there is actually more than one coil of wire within a coil,

can i say coil a few more times to coil a few more coils.... errr .... i mean people.

i dont know weather it is practical or achivable to to have more than one set of coils within the same casing, or weather this is infact what they all use,

[andyhardy]

I only said one coil per cylinder going by what my FRST was running previous to the Cossie management.

When you take the actual coil pack block off the engine you can see that it's divided into 4 segments.

Upon speaking with some really experienced mechanics/tuners on the subject of why EEC-IV is better than the older coil based systems the answer was that the biggest factor is the power of the spark. Older coil systems have disadvantages with the mechanical distributor as you say, but the other problem is that a single coil can only produce so much power for the spark, so when say something like a Cossie is running much higher boost than standard you see the owner changing to a Group A coil, purely because the spark produced will be much stronger than on teh standard coil. The implications of a weak spark as I can see it are that at higher boost levels the spark will (in laymen's terms) 'be blown out' meaning misfire at high rpm, and we all know that's not good! The EEC-IV setup (particularly OFAB due to it's ability to use higher psi reading MAP sensors - that's another argument for another thread though) produces a much much more powerful spark in all situations, meaning that the spark should never get blown out even when running the car's theoretical maximum boost - no need for a replacement coil pack!

I'd be interested to see if Ford changed direction with their ignition systems on cars post EEC-IV - it's something I've not actually thought about at all!

I know that car's like the Focus ST170 and the like use much more integrated ECU systems - it sounds like a CANBUS system really where a much simpler loom is used in terms of amount of wires but the ECU itself is far more complex in terms of programming and CPU power due to the number of components on the car it deals with - including switching the alternator charge off when the car is under acceleration etc. (to make sure bhp is used for the car going forward rather than charging the electrical system).

Cheers,

Andy

andy i understand (and know) everything in your post

i know you said one coil per cylinder - doesnt mean thats how i read it

so are you saying that you know for a fact the FRST uses a coil per cylinder (you havent said so in as many words) and as you proved yourself just because the spark is good and strong doesnt mean its got coil per cylinder,


also as you said think we need another thread for this lol

Nope - as with all my posts Ian they're based mostly on assumption.

That assumption being that I'm right!

Sorry for thread hijack - keep us updated Asad (I'm sure you will!)
