depending on price and features I may want a few cars worth.

88' Porsche 924s 4<-4cyl
92' Alfa romeo <-V6cyl 60degree
90' Nissan 240<-4cyl
XX' Gm series II L67 <-V6cyl 90degree
99' Miata <-4cyl

maybe few lawnmower engines worth too, but we'll see a little latter.

1. On board IGBT ignition drivers - Preferred but can handle them being in the same case (I dont want multiple boxes)
2. On board low Z injector drivers - Must for me, I dont want to replace my brand new Racetronix 120lb injectors and resistors are a turn off and generally suck overall IMHO
3. Thermistor self heating prevention :-p
4. NO thermistor self heating prevention
5. Current feedback circuitry on injectors - Probably yes
6. NO current feedback circuitry on injectors
7. ONLY SMD components - Slightly opposed since some SMD look like a bitch to solder but ive never tried so I dont know first hand
8. ONLY TH components - Neutral
9. SMD components supported - Neutral to positive, I can handle some SMD
10. TH components supported - Neutral, I like TH but they do make for a bigger board
11. X primary fuel channels required/preferred - Require 4 Low Z
12. X ignition channels required/preferred - Require 2 (wasted spark), 4 would be great for future "just in case"
13. X auxiliary low current low side drives preferred and required OnOff / PWM - Boost control!!! Water injection solenoid control would be nice, probably two so that there can be an IC sprayer. Water inj/IC sprayer can be general outputs though
14. X auxiliary high current low side drives preferred and required OnOff / PWM - Nothing jumps to mind beyond a way to control a pump for water injection, so probably 10-15 amps for a Shurflo... A low current relay output would be ok here as well
15. How many boards? - Ill probably buy 2

Id also really like a knock input, I am about to buy a Link Knockblock so onboard filtering isnt a must now, just a 5 volt input. Also, 2x hall inputs (60-2 wheel with hall sensor, and a hall cam trigger).
