well i have just finished putting my megasquirt ecu together and would just like to feed back to the members here how hard/easy it is to do
you need to work out what you actualy need as there are all sorts of varaitions on engine hardware like dizzy or no dizzy, edis etc this also effects what type of megasquirt you are using or need and version of pcb
and the input and ouputs you want (some can be added later if needed)
and you WILL need a thing called a stim (emulates engine in/outputs) jimstim is best to go for as it has vr signel output of almost every pattern you will ever need.
im going for a zetec so its a 36-1 vr trigger pickup and a wasted spark (two coil) direct out put so an extra coil driver is needed and v2.2 pcb has no circuit for vr it has to be made so v3.0 is what i needed this should be standerd fo almost all four pots that we are fitting to the roadster
(go for ms2 + extra coil driver on a v3.0 pcb for best results)
as you put it together you will need to add or remove parts from the build as you go use the msextra.com build guide and parts list called "BOM" and is the best place to look for any info or support read the guide twice first befor you start your build
most of the soldering is fairly easy for me but i have built loads of hobby eletronic kits in the past and if you have no idea i would say its best to have some experince and idea what all the diffrent components do.
there are a few small transistors that are tricky to do as the gaps are tiny
and dobble check every part as you fit it (i did make 1 stupid mistake)
then you will need to send the firmware into the chip this requires you to use programs and rs232 leads i had no trouble but this can also be tricky if you have no idea what you are doing
what i need to do now is do the engine settings bit have to see how that go's
