two lambda inputs

i have some questions
1. two lambda inputs for bank selective fuel contoll are possible?
2. is a new standalone ecu in development?(dbw included)
3. Bmw M3 S14 has two sensors on the crank, must a cam sensor installed or can the "crank-tdc-sensor" used for syncronisation ?
4. where to buy a pnp solution for usb logging.

If you have TDC mark on crank, you know the 1st piston TDC, but you will not know if this is the working cycle or the exhaust cycle. The cam rotation is 2 time slower than crank. So if you have TDC mark on CAM, you can tell when should you cpark and inject.
............... but , you can still run waste spark + pair injection and use just crank sensor for timing.

1) it's not possible
2) Yes it is
3) BMW's s13 engine has distributor so it doesn't need CAM sensor for sequential ignition. Fuel is probably connected in pairs .
4) We are working on it.

cool
so new ecu will have two bank o2 control and dbw
for building an pnp adapter for bmw S14 engine , is it possible to buy emu-ecu-connector for soldering on a circuitboard?
