My initial thought would be to place the sensor so early in the exhaust 
stream that you are able to calculate it based on rpm/map and travel 
distance. You would have to have them so close that there would be no room 
for a second pulse from the same cylinder. Of course it would be the 
simplest if the pulse reached the sensor before the next one fired at any rpm.
I am not sure if this is practically possible, but If you are able to see 
separate pulses on the sensor it sounds that it should be possible at least 
up to a certain rpm point.
