There really is some stupidity and ignorance in a lot of these responses. I like the ones that try to call it a primary and secondary “coils” look there is primary and secondary voltage in a coil. Your primary voltage is the the battery (normally 12vdc) secondary voltage is the one that pops that ass. They need to hook the secondary voltage to the children responding to this thread. Look guys this mod works. If everyone wants to disprove that nothing is being changed then. Change the wires around on the other coil persay and see what happens. For real change your intake coil to the same orientation as the exhaust and all of you ignorant have a lot to learn children will be silent from now on. For clairity im saying do this to the intake to only prove that changes are being made. BECAUSE IT WONT RUN. The mod is to do the exhaust. I’m tired of all these people telling everyone that this doesn’t make a difference because it does. If your reading this it will give the 2.3 a little more power. All these people saying it don’t work don’t know shit about shit they are just spewing retardation. I mean 1 guy put a wiring diagram up as his proof. The guy who started the thread is right just try it if your stranger has a little miss or is not running right you have nothing to lose. Everyone trying to disprove is all stupid
Welcome to TRS
There was a Primary and Secondary coil on the 1989-1994 2.3l, the secondary was prevented from sparking while starter motor was active, well actually anytime RPMs were under 400,
In above diagram look at "DIS" module's 2nd wire from the left, pin 6/DPI, thats Dual Plug Inhibit (DPI) circuit, the Computer/ EEC, stops spark on Secondary coil for start up
1995 and up 2.3l/2.5l didn't use the DIS or the DPI function
Primary was on exhaust manifold side, so only those 4 spark plugs would be "on" when starter motor was active, at 400RPMs Computer would allow Secondary coil to start for dual spark
There is no "alternating" with dual spark plugs, or there would be no point in having dual spark plugs
Dual spark plugs give better performance, thats why they have been used throughout the years.
4 Valves are better, so dual plugs are old fashion now-a-days
Although the Dodge HEMI used dual plugs
Spark plug mod
Can't help performance, simply not possible in our reality, laws of physics apply, if you can change the laws then perhaps it would be better to change the laws of probability and buy a few lottery tickets instead
Any way the 2.3l has 2 coil packs with 2 coils each, so 4 coils total
Each coil fires 2 spark plugs at the same time, one coil pack coil does 1 and 4, the other coil in that pack does 2 and 3
Other coil pack does 4 and 1 and then 3 and 2
1 4
2 3
4 1
3 2
so changing it to
4 1
2 3
4 1
2 3
Does what?
yes nothing
Ford uses Waste Spark, very first spark system ever invented, 1890's I think, super reliable, spark is based on the CRANK SHAFT position, not cam position like a distributor did
So each spark plug fires at each TDC(top dead center) of its cylinder, no it doesn't spark on exhaust stoke for better emissions, it sparks on exhaust stroke because its a Waste Spark system timed by the crank shaft
As long as both spark plugs fire in each cylinder then that's the best performance you can get from this spark system
