resistance of the wire is the same at any given point
but the longer it travels the slower it will become
So as the lengths vary a bit
I suppose what they did was to add a compensation factor to the end of the shorter ones so that the energy would travel at the same speed even though some had a longer distance to travel

Now that does make sense to me...
as you want to fire the plugs at the appropriate times wo the travel time lag which I don't thinkin a few inches is alot
but its good to have it compensated for

I measured the bosch wires
they were not exactly the same as the MB

Yeah would like to see what Bosch is doing
but it seems like they are not adding that compensation factor to bring the end voltage at the same time in all the wire lengths



I think what really matters is that the end resistance in all the lengths be the same.
You didn't measure each one did you?

That would interest me

I'm thinking the most important thing here is the timing as you want to ge that spark thru to each plug at exact same time wo additional delay from extra resistance caused by longer travel length.

The way I understand it the plug should be able to handle the resulting voltage & only as much that iis necessary willbe used to jump the gap

The equation is
E=IR

I is current
R is resistance
E is voltage

I don't see a factor for distance etc length of wire
but it has to comeinto play
I think?????

current is in sense s time distance factor
as its what moves thru the wire
& its speed is affected by the resisitance of the wire
Maybe resistance is not cumulative?

Its been a lone time since I took physics & electrical courses

LOL

HELP

Where r the electrical gerus'
