Those homepages are little messy and my lousy english doesnt help me. Can i get full kit including all necessary parts or do i have to get some parts from SP-Elektronikka after wards (if yes, what parts?). Of course i have to get temp sensors, injectors etc. elsewhere.

you have to buy the bits seperately now. the 'grounp buys' are over and gone.

Quote:

I assume that you assembled it. Was it hard?

not really, just take your time.. ever used a soldering iron?

Quote:

What parts where hard to find?

Do I have to be fakir to complete the assembly?

And i have signed in but members only area havent opened.

there's a list for digikey to buy all the parts, i know they have both a us and cdn dist, not sure about aus. if i were you, i'd just get someone from here to assble the parts, and ship it in a single package to you

think its better if u get the bits urself, the 2nd group order finished ages ago and i havnt heard anything bout another, the hard part to get i think is the MAP vacum sensor, if u are running with either a turbo or supercharger, the part stated needs to been changed to a higher rating one, the standard 1 cant handle the higher pressure. im currently thinkin of building one myself with a few mods for my 2t-geu once i get it runnin , sounds alright since its simple and easy to modify

the sensor that comes w/ it, is the 2 bar map. you can run an s/c or turbo under 2bar w/ it. youll have to get the bits gathered yourself, the g/b is over. just selling the board/chip/map setup now

You can quite easily use a MAP sensor off another car... all MAP sensors are quite similar, just they have different pressure response curves.
It would be quite easy to mount a diff type of MAP sensor in the engine bay (ive got a Bosch engine bay mounted MAP sensor here), wire it to the megasquirt using shielded cables and use the utils to generate new MAP sensor tables.
The MAP sensor im tlaking about here is a common part in Aus, i pulled it from the engine bay of a car (cant remeber what it was) at the local u-pull-it.

ya, map sensors are the same, and mounting is easy.. but if you can't get it running because the curves, pinouts or signals are different, don't blame the ms..

Getting the MOSFET they use for the injectors will be difficult, but dicksmith sell the 60N06 which will do the job fine, if not better (ignore thier data for it in the back of the catalog, the RDS-ON rating they have given is wrong).

The MOSFET driving IC will also be hard to get, but TI make a similar part (same pinout, function, and faster) that will do the job that can be got using thier free samples web page (itll arrive in about 2 weeks).

The uC (microcontroller) should be easy to get, but youll have to make your own programmer for it... MS kits come with it pre-programmed.

just get someone from north america to gather the parts, and ship them off to you..

BTW... i havnt made one, if it sounds that way.
But i have researched it a lot. Im using some of its ideas in a Injection/Ignition ECU im developing.

cool, g'luck
