latest update...
so how does it compare with other systems? very favourably.
mmm 100MHz, 32bit.......

stewart? do you think the PWC part will be standard part of EMS? or just option for thos with testing gear (for calibration).
i know the 12x12 table(s) will get a lot of doubter's re-considering megasquirt (ed?)

okay..
josh, get in line  we will be doign a GB as soon as the parts lists and boards are released.
Charles (did you get those wiring diagrams yet?) i believe the PWC will also be available as standalone unit.
i know that there are a number of people (me included) we are looking to set up calibration stations for the sensors. in the end there may be a set of parameters that wil allow an off the shelf sensor to be run.. for this i'd want about 0.2AFR accuracy.. the calibration is for the 10tenths thing i think, but we'll see.
PWC will be part of UMS (but will not necessarily need to..) the idea is 12x12 AFR table.... none of this VE or ms crap.. true real time AFR targetting 
EDIT: it will definitely have narrow band O2 sensor support as well, so will not require purchase of the Bosch LSU4... the features on UMS will be of the range where people will want to go with the WB tho..
Ed, sorry, this is just a tease end of this year looks realistic...
Chris. how does it compare? the plain MS is as good as microtech or better (depends on model) it has 8x8 table but you select the positions (ie 1kpa and 100rpm steps) it does low and high impedance injectors.. it does closed loop. has warmup enrichments, barometric correction etc etc etc etc..
the first release of the software will probably be for single coil. the hardware will all be there, and will just need software update to run more coils.. the bueaty of it is configurability (is that a word?) you set the 12 channels to be whatever you want...
the UMS will blow many ECU's out of the water... it will have an excellent software interface... RTOS means that some ppl will put linux ON THE UMS, so just needs to plug into dumb terminal...
ethernet connection to PC, REAL TIME AFR targetting means that all you have to do is set AFR's and away you go!
i believe it will initially use an internal Motorola MAP sensor as MS does now.. currently it is the MPX4250AD? basically uou have 1.5BAR boost capability so far. swapping in better MAP sensors is not much of a drama... how much boost you want to run? there are people runnign plain MS with 2-3BAR already.
12x12 rpm increments???
ok. MS is 8bit. it has 100rpm increments.
UMS will be 32bit. it will most likely have either 10 or 50rpm increments..
thus you could set your table up to be 1000-1120rpm if you want.. the positions of the points are fully configurable... ie 600,1000,1500,1950, 2220, etc etc.. whatever you want.. none of this "set table" crap 
same goes for MAP... i know of a guy runnign his MAP table as (on MS)
60, 80, 83, 86, 89, 92, 95, 98 kpa... which is the top two load bands on Wolf... it runs beautifully, and uses +-20% O2 correction to keep cruise AFR at stoich.. (idle and cruise MAP is 75kpa, ie 25kpa vacuum)
basically, it is a 'next generation' type of deal// all the features you want, completely open source (ie write your own code if you want) etc etc...

should i also mention that there is an MS2 upgrade in the works that utilises a 16 bit motorola 68HC912 chipset?
this is even more hush hush than the UMS, but rumours are 12x12 table AND single coil ignition support too... basically Megasquirt and Megaspark rolled into one.
in the end, the original MS is enough to control 90% of engines.
sure it only has 2 banks of injectors, only does single coil spark (with MSnEDIS, or MSnSPark, or seperate box Megaspark), but how many engines NEED this? the MS already does staged injection with seperate tables too!

Karl: you might want to also talk with Bowling & Grippo about licensing out production of kits ... there was a thread on the new MS forum about some US electronics-assembly company making complete/assembled kits.
but it would benice if we could source a lot of this locally! would make life easier for stewart & eddie who have nor organised four group buys (i think).
Stewart: i got the wiring diagrams - thanks muchly! ... it will be very handy now as i've had to conclude that my old Haynes manual must have gone chucked out accidently with the paper recycling - was last seen on dining table next to a stack of newspaper... ;(

Karl,
thats a nice kit, but is basically a input signal modifier... it is much better than some others around as you can modify the inputs based on a table, but it is still just modifying a stock ECU..
the UMS is toootally different...
as for kits...
the general rule is.. if you buy the partial kits (PCB and MAP sensor etc) from Bowlign and Grippo, then you have the full support of the forums etc..
if you create your own PCB's, you MUST provide support for all those people with those PCB's...
personally i'd like to see component kits available, or reselling a total kit with the partials from them.... not sure how that would sit with electus?
anyhoo, we'll work it out... currently there are a few bits that electus just cannot supply, and a few that not even RS or Farnell do... or they are just hideously expensive...
if we could wiggle it so these parts. and furutre UMS parts can be supplied at a competitive cost by electus.. all the better for all of us

i agree. when you have races and money on the line.. and have a spare 3-5grand for a MoTec, i would to
but for about $200, i very much doubt you will find anything better..
btw, can you reprogram MoTecs? is their software open source? i guess the answer is that you can pay to have certain features unlocked or upgraded..
but thats not exactly DIY now is it heh heh
MoTec for serious ppl
UMS for DIY ppl.

Karl, thinking abotu the upcoming Jaycar kit, i think that would be good when you are fitting larger injectors and you can reduce the AFM/MAP signal to reduce the fuel delivered... not sure how good it would be for increasing flow from stock injectors, but for adding larger ones.. seems easy solution..
you could do other funky things like higher pressure MAP sensor, and compensate for it's different output...
could be quite a nifty little box
