I'm against MAP in general...also I have an ST162 air-flow meter
what other methods are available to control NO(x) emissions (ie high combustion temperatures)?
Cold start injection - how do most cars deal without it?
As for logging, I'm not overly fussed...aside from an RPM signal and preferably some kind of diagnostic port any other logging functions are a bonus.
As for the whole ignition debacle. I went to the MSEFI website earlier today, there were about three options THe third option being EDIS, which I'm still convincing myself of, does anyone have any links to further information - it's cool if you don't have one on hand I'll just go for a search 
I'm guessing I will need some kind of CAS for the ignition (forgot to write that up).
Lastly - knock sensors. I'm interested in these because I'm planning on running a fair bit of compression (in the range of 10.5 : 1)

ok.. MAP is pretty good in general, but you can make the MS work with AFM also.. it's just a matter of calibrating the signal to be 0-5V i guess.. the MAP is good as it is easy to work with in terms of understanding whats going on.. whereas % of AFM is a little more vague.
control NO(x)?? lower compression ratio 
cold start injector? you don't need it if the ECU can change pulse width based on temperature correction and afterstart enrichment (like MS does) cold start injectors are pretty archaic in EFI terms.
logging. MS can log all it's parameters (when hooked up to laptop/PC) and is only limited by your hard drive size. sample time can be around 50ms i think? depends on your serial port i suppose.
ignition..
Megasquirt n spark
Megasquirt n EDIS
Megaspark

the first two are software change and use standard MS to run both fuel and spark. MSnS will run a dizzy based ignition, MSnEDIS will run wasted spark.
Mspark will run EDIS or dizzy based, and MJLJ runs EDIS (i think)
for the EDIS, you will need a 36-1 tooth wheel (like lots fo fords have) and a VR sensor. for the others, you can use points as the trigger, or halleffect, or VR dizzy
hmm high comp and low NO(x) hmmmm... performance AND emissions is always difficult. you do have a cat right?
