[Diy_efi] Spark timing above 1 bar

[pr asdf]

I am currently looking at finding a way to delay the timing, basicly I need 
a circut that waits for a change in input state and changes its output to 
match, almost instantaniously while under normal conditions, (less than 1 
bar), but delay the state change by as much as .0016 sec (10 degress at 1000 
rpm) or as little as .000025 sec (1 degree at 6500 rpm). I plan on 
programing and adjusting the tune with a laptop, so calculating the time it 
takes to retard X number of degrees at Y rpm can be done beforehand and then 
to keep it simple, just load the delay time into a look up table for the 
microcontler to apply. The main part is how to create the delay, without a 
delay under normal circumstances.
The lt1 engine is also still a single coil, direcly controled through the 
computer, and is split to each plug by a normal distributer (if you can call 
an optispark a normal distibuter).
