I'm just gonna run some large resistors instead of the actual
injectors, like 20 ohm, 10 watt.  Should be able to do dwell
meter or scope off of that.  While the P+H drivers would be
"confused" by not seeing a big load, I don't think this will 
interfer with the actual signal processing....

Yes, but the "Electronic Ignition" coils have a lower 
resistance, hence less spark energy.

 What would I be losing to do that?  I hate to see that bright
