maximum ON before damage

[Bruce Plecan]

| They are a bit slow to open and thus have a higher minimum ms before
| stability is reached. approx. 2.5 ms.

That number isn't even close to what diacom displays for a AUJP BCC, in a 90
1227730 ecm'd v-8.  At idle..

| Lower resistance injectors are high current devices that must be
| handled with respect. They will draw 3-5 amps and will self destruct
| in seconds with out current limiting. The usual ratio being 4:1.

Not from what I've seen.

| They are fast to open 0.4 - 0.9 ms and thus need to be limiting very
| soon after saturation.
| The limiting factor with any injector is the max. time in ms available
| at max. rpm. If that rpm is say 6,000 rpm we have 10 ms total.
| If it takes 1.2 ms to open (saturated type) and 1.1 ms to close you
| only have 7.7 ms left. Just to make things difficult the first period
| of 1.2 ms has NO flow. So really that 2.5 ms lower limit (for
| stability's sake)
| means you have 2.5 -8.9 ms to play with.

If it takes 1.2 to open, how's it run with an injector pulse width of 1.1 at
idle, or even 1.3ms.

Just curious how the numbers work here
