home build ecu. any good.

[myseatcupra]

i wana do some engine mods. and have read that the sandard ecu isnt up to much. so i need the brains of scn to help me.
first off megasquirt/megajolt are they the same thing?

what ecu would i need.. i'd like to use a waisted spark system ,,ford edis?
is it ms v3 that has the driver to the ignition set up? do i need a wide band o2 sensor. or is the one fitted to my car the right one?
can any one give me the list of parts i need
i.e model of ecu board, wiring loom and anything else. and a good shop site to get it all from.
and one last thing are the ms ecu's any good. have they any problems
i've looked at so many sites im lost as to what i need.

i'd watch out as type approval is alleged to be coming in soon and it will render the megasquirt illegal for road use and mot

which i agree is utter crap but hey - we all want a greener planet

dont know if exactly relevant as most of its V8 stuff but these may help

megasquirt is what you need. megajolt can only do spark.

MS, with MS&E code does spark & fuel. It can run your distributor, and all your sensors.

The 16v only has a narrowband, but you don't "need" one to run

easy to build & test. Buy a relay board though - it makes the wiring much easier. and a relay board cable.

I bought my bits from the USA.

It's not plug & play though....

 

[Fl@pper]

how much you get yours for m0rk ?>

guy at work had a v2 a while back built and loomed up delivered for £250

 

[m0rk]

Considerably less... but I built mine

$139 - http://www.diyautotune.com/catalog/megasquirti-programmable-system-pcb22-unassembled-p-28.html

You'll want a Stim as well

 

[myseatcupra]

just being a bit dim here. thats the ecu part. then i got to buy the loom? and you recon i need the relay bourd to.. i read that it all need setting up once built.

 

[Fl@pper]

correction it was $250 sorry and from the same place - lol

wanna sell your stim board ? mind you they are cheap enough anyway

 

[myseatcupra]

so is this what i need then mork

http://www.diyautotune.com/catalog/megasquirti-relay-cable-p-47.html

and an edis coil pack. is the stim for testing? if i've listed everything i need thats $344 or £175 not bad really

 

[Fl@pper]

you'll need an ecu as well or a kit

thats just:
relay board
wiring loom
relay connector cable

if i remember rightly (been a while) msI only does injection you need MSII for both injection + ignition

 

[m0rk]

You don't need the 12' harness if you have a relay board.

A stim is for testing & setting up (I borrowed mine from a guy at work)

It needs a lot of programming, so isn't for the faint hearted.... it's straightforward enough though

 

[m0rk]

if i remember rightly (been a while) msI only does injection you need MSII for both injection + ignition

MS1 with MSE&E will do fuelling & spark

 

[myseatcupra]

how do you connect the relay is it just a few wires then no need for that loom. cheer for the help mork

 

[m0rk]

it tidies the wiring loom to make it easier to do this:

 

[myseatcupra]

i think i got you so its only got about 6 wires running to the relay?
one thing i was thinking will the ignition key work or is that locked to the oem ecu

 

[m0rk]

erm no.

out of the relay board is about 20 wires. but about 14 go straight into it from the DB37 connector.

 

[myseatcupra]

ok i'll have to look in to this. i can see how that diagram works.

 

[Fl@pper]

i reckon it'll be easier on the 16v than converting a twin carbed / points dizzy Rover V8 - lol

 

[myseatcupra]

do you mean like this

lol you can do mine then big mouth

 

[myseatcupra]

i got it now i think the Relay Board has its own loom. ecu to Relay Board then wire up all the inputs
