We are needing to log data from digital automotive ignition systems to determine the rev limit and ignition curve. The method is straight forward but not sure about the electronics on this one. Basically, we need to supply a power to the ignition box via function generator or whatnot, and a .1V triggering voltage at 1-2 pulses per crank revolution. The ignition box will compute the frequency of the trigger pulses per sec to determine how much advance to add or remove.
We basically will just need to vary our trigger pulse from 1-15,000hz and read the relation (delta) of triggered event and ignition box output event. It would also be useful to look at the amplitude of the input and output. I am figuring we would need to read at about 100K reads per sec which is roughly 1 read per degree of crankshaft rotation at 17K rpm. The faster the better probably.
We also need a travel friendly setup for this. A local shop runs labview that we can use but we do not have this on our own computers so not sure what we might do to set this up and log with a PC.
Ideas?
