Crankfire vs. Distributor????, anyone have hard numbers???? Options

[Mueller]

Does anyone have dyno numbers or know where to point me to for a comparison between the two different types of ignition??

Knowing that I can turn my regular distributor into a fully electronic programmable electronic ignition (okay, it'll still have the rotor which must distribute the spark) I was wondering what the crankfire has over the distributor ignition besides 0 moving parts that can wear out.

for the distributor the path for the spark still needs to go from the coil>rotor>cap>sparkplug wire>sparkplug....

the crankfire is coil>sparkplug wire>sparkplug

what effect does the rotor and cap have on ignition if everything is the same (advance curve and coil rating)????

It's in the box. It's indexed via the dowel on the fan hub. I know it has to be part of the balance and once it's in it has to stay.

Yes, I'm gonna include it in the build as the spacing washer on the fan hub. I'll have the VR sensor on the cooling shroud but I'm gonna start the engine with a Mallory, get a fuel map that isn't dangerous, then tune the fuel map with the O2 sensor. When I'm happy with what I've created, I'll get some chassis dyno time to even out the the fuel map and tidy up the ignition. Programmable ignition is the last thing I would like to add. I think I'll have enough challenges building it and getting the fuel right. It's best to change as few things as possible at any one time.

I love gadgets and I like to fiddle but, right now I don't believe programmable ignition adds a lot until knock sensing or ion sensing can be incorporated. The Megasquirt people will include the ability to use the Ford wheel and VR sensor in future versions. If, in the future they incorporate sensors, which they will, to run the ignition closed loop I'll be all over it. As it stands now I'm gonna watch and wait.

At times I'm a little crazy but I'm not nuts, so I'll take it one thing at a time.
