Megasquirt upgrade to MS-II and 3-bar Map HELP
 

Hi all,

I've just started building my engine and figured i should look ahead to megasquirt fitting etc.

I want to upgrade my current MS1 to MS2, is this as simple as buying an MS2 daughter board and plugging it in? And where is the best place to get the MS2 board?

Secondly, im pretty sure my current ecu has the 2-bar or at best 2.5 bar map sensor from digi-key, what 3bar map sensor can i use? can i use a cosworth 3bar sensor?

Thirdly, my ecu was originally from M-tech automotive, it has the coil pack drivers etcetc, but i read the megasquirt ecus from M-tech were not legit? is this likely to cause me issues when loading new code etc....

Any advice would be great.

Thanks very much!

Rob,

The ECU's have the MAP sensor built i, so will have to get one that will fit in place of your current one, Cossie ones are external?

If it's an early M-Tech ECU then from what I have heard they are fit for nothing but the bin Rob :(

In fact I have a dead one sitting right here!

Which was sent out to replace an earlier one that died! :cry: lol

The new stuff is said to be much much better though!

Oh cock lol

Apparently you can fit a GM 3-bar map, not on board just wondered if any one had.....

Guess i should buy a megastim too then :( what failed on your ecu Karlos? I think the one i have is a later one as the case is different, i'll get some pics up.

And also, can a tach output (from the ecu) be bodged up?

Rob,

It's not actually mine it's a mates, cant remember what happened to the first one but this one doesnt power up.

If you dont mind buying a new one I can get MS2 ECU's with 400kpa (38psi) map sensors and tacho output as standard for a good price?
I get a nice discount as I've bought quite a few now! :D lol

PM me a price if you will mate, budget is getting tight :( so any discount is well worth it lol, are these with coil drivers on board?

Cheers mate,

Rob,

Yeah mate everything ready to roll, drivers, Tacho, 400kpa MAP, loom, Data cable, Docs, software, etc...

PM on it's way...

Karl your a legend lol,

Rob,

how much would it be for the full conversion karlos as ive got gotech mfi and dont run a idle control or cold start and thinking about changing soon....

or might just get it for the missus duratec for her mk3

PM'd Mark...

Also if I were to order a few at once we will get a better price again!
I need one for the GF's Ka, so with your maybe 1 or 2 Mark and Robs 1, should get a nice price, if we can order all at once of course.

You can take a tach signal from one or both of the coil inputs mate :king: also if you wish to run an external map sensor its possible by extending the three wires from the board out of the case, same as your throttle pot is, hope this is of help.

Cheers mate :)

Would the coil feed not make the tacho half read? and do you use an external MAP?

Rob,

I will be using an external map with my new ecu :top: it would half read if you used one coil, or work correctly if you used two, with a couple of diodes to stop the signal travelling backwards and setting off the opposite coil, or if your using edis then there is a tach output on it.

Lovely! spot on and makes sense lol

Cheers mate :top:

was going to fit OFAB setup but how much would it cost for a ms2 setup?


Thanks

Luke

Drop Karlos a PM mate, he will probably see it sooner. But generally speaking if you are going from mfi to efi bank on 450-650 depending on how and who does it.

Rob,

will do.

i've taken the mfi out, i've got everything from a fiesta running OFAB. Plan to all the work myself.


Luke

Have you sorted a cps out? you using a fiesta block and flywheel etc.?

Bank on another £500 to get it running i should think, but i guess you can sell the OAFB shizzle you don't sell.

Rob,

if you have the efi parts then all you need is to fit them and use the ms ecu with that and then get it mapped .....

thats what ive been told?

Thats right Mark, if you have all the EFI parts fitted, just a case of fitting the plug to the end of the MS loom (inlet manifold, coil pack, CPS, etc..) and get it mapped!

See my thread here for everything in detail.. https://passionford.com/forum/ford-e...quirt-efi.html

should do a group buy on megasquirts my mate is after 1 so put us down ;)

thats what we are all thinking mate ....

then we can pick karlos's brain on how to mapp it lol
