Pretty interesting read wonder if it can help any.
I came across that site a while ago, pretty interesting stuff. I'm hoping I can learn something reading through the code.

Just realized I haven't updated in a while, got the sensor circuit working for real this time. Turns out the data sheet has some pretty helpful information . In all seriousness I was looking at things the wrong way, once I took the time to understand what the MAX9925 was actually doing I was able to set everything up properly.

Also hooked up a test circuit for the LM1949, seems to be firing the fuel solenoid properly. Gonna have to borrow a current probe from work one of these nights and have a good look but the voltage profile across the shunt resistor looks promising.
