Most street bikes (not all) do not currently use an O2 sensor, so minor adjustments to the fuel delivery are possible and needed in different parts of the RPM range when aftermarket upgrades are installed and will help smooth out the power delivery. You'd be surprised how much a little improvement feels "at the seat of the pants" to the rider. Maybe you already know.
Now the +/-20% range is adjustable and will probably never see 20% and may be reduced to some narrower range in the end, but until then, I'm starting at +/-20%.

Now since I'm taking your advice to sample the leading pulse to configure the next pulse out, I downloaded Mr. DT's Instant Interupt-14 super duper program template and aww man, all I could do was look straight up! You guys are in the zone to understand this stuff. But if I'm gonna eat that elephant, it'll be one byte at a time.
Quick question,... will I need to have a PIC device with 4 timers to be able to trigger off 4 inputs to "sample one, build the next"?

Thanks
